feat(tabs): Tab Layout setting with by case (A) and ledger (B), reversible state order, cleaner tiles (#426)

Tab Grouping becomes Tab Layout (tabArrangement: 'state' | 'case' |
'ledger' | 'classic', default 'state'), the first row of App Settings,
Appearance, Tabs, so the old and the new strip are one choice apart.

- By case (option A): each case's tabs sit in one .tab-cluster box in
  first-appearance order, labelled with the case and its count, coloured
  by a stable hash into the session palette. Membership is
  _mobileOverviewCaseFor(), the home screens' own match. Inside a box with
  company a generated w75-api-gateway reads w75; the -<case> stays in the
  DOM in a .tab-name-case span only .tabs-clusters hides. The incremental
  render path rebuilds only when the cluster structure key changes. The
  rail and the sidebar get a labelled section per case; phones dissolve
  the boxes into the chip row. Drag stays inside one box.
- Ledger (option B): CSS only on .tabs-ledger, desktop header strip: an
  auto-fill column grid of equal cells in mono type with a 3px status
  bar. Its markup is identical to classic's.
- State Order (tabStateOrder: 'urgent-first' | 'urgent-last'): flips the
  by-state groups so needs you can be the bottom row.
- By state: the label column is measured to the widest label on screen
  and the labels are right-aligned in it, instead of a fixed 92px gutter
  that left short labels far from their tabs.
- Tiles: a three-row grid (label, value, bar) with pixel line-heights in
  the bundled JetBrains Mono, 36px like the header. The bar used to lie
  over a fixed 28px tile, and a taller system mono (SF Mono) pushed the
  value into it. The WS tile's grid moved onto an inner .connection-tile
  span because JS writes the indicator's display inline. Compact uses the
  same font and a matched WS size.

Tests: test/tab-clusters.test.ts (new), plus the rename and the reversed
order in test/tab-triage.test.ts.

⚠️ Mobile no longer hoists the active session to the front of the strip: that reordering ran on full renders only, so tab order flipped depending on which render path fired, and it renumbered the Alt+N badges. Scroll-into-view replaces it; do not reintroduce it.
### Tab grouping by state
### Tab layouts (by state, by case, ledger)
**Tab grouping by state** (`tabGrouping`, per-device, default `state`; Discussion #426 option C): the tab list is split into four groups, most urgent first: **needs you** (a permission or question dialog; a failed session joins it), **waiting** (idle prompt pending), **working**, **idle** (also ended sessions, an agent that exited inside a live pane, and web tabs). The desktop header strip draws a row per group with its label and count in a left gutter; the flat vertical rail and the sidebar draw a section per group; the tablet strip (600-767px) keeps its scrolling row with the headings as inline dividers; phones keep their chip row in group order with the headings hidden (mobile.css). Classification is `_mobileOverviewState()` + `_mobileOverviewExit()`, the home screens' own, and the fold into four groups is pure in `CodemanTabTriage` (constants.js, `computeTabTriageLayout()`).
**Tab layouts** (`tabArrangement`, per-device, default `state`; Discussion #426): App Settings → Appearance → Tabs → **Tab Layout**. Four values: `state` (option C), `case` (option A), `ledger` (option B) and `classic`, the strip as before. `<html data-tab-arrangement>` is stamped pre-paint and by `applyTabOrientation()`; the render paths read it through `isTabTriage()`, `isTabClusters()` and `isTabLedger()`. Named groups in the vertical rail (owner tab layouts, `_projectTabGroups()` non-null) win over both groupings, and the grouped tree renders as before.
⚠️ **It is the flex `order` property, never a DOM reorder**, exactly like the sorted rail: `#sessionTabs` stays in `sessionOrder`, so the Alt+N badges, drag, the keyboard walk (which already sorts by COMPUTED order) and the sidebar filter keep reading the list they always read. Each group owns a band of `TAB_TRIAGE_STRIDE` order values: its heading, its rows, its web tabs, then the row break that ends the header line. The headings and breaks are `aria-hidden` direct children of `#sessionTabs`, reconciled in place by `_syncTabTriageChrome()` after BOTH render paths, because a state change is an incremental pass (no tab added or removed) and can still empty a group or fill a new one. An unchanged pass writes nothing.
**By state.** The list is split into four groups: **needs you** (a permission or question dialog; a failed session joins it), **waiting** (idle prompt pending), **working**, **idle** (also ended sessions, an agent that exited inside a live pane, and web tabs). `tabStateOrder` (`urgent-first` default, `urgent-last`) decides which end they start from; only the group order flips, never the rows inside a group. The desktop header strip draws a row per group with its label right-aligned in a left gutter that `_sizeTabTriageGutter()` measures to the widest label on screen (re-measured only when the label text changes, and once on `document.fonts.ready`), so no row carries a fixed gutter's worth of empty space; the flat rail and the sidebar draw a section per group; the tablet strip (600-767px) keeps its scrolling row with the headings as inline dividers; phones keep their chip row in group order with the headings hidden (mobile.css). Classification is `_mobileOverviewState()` + `_mobileOverviewExit()`, the home screens' own; the fold into four groups and the order bands are pure in `CodemanTabTriage` (constants.js, `computeTabTriageLayout()`).
⚠️ Inside a group a header row keeps TAB order, so the strip only moves a tab when its state changes; a sorted rail ranks each section the way it ranks the flat rail (`_tabRailSortOrder()` feeds `pos`). Drag stays on in the strip, but `_isTabDropAcrossTriageGroups()` refuses a drop on a tab in another band: the dragged tab would stay in its own group and land where the user did not put it.
⚠️ **By state is the flex `order` property, never a DOM reorder**, exactly like the sorted rail: `#sessionTabs` stays in `sessionOrder`, so the Alt+N badges, drag, the keyboard walk (which sorts by COMPUTED order) and the sidebar filter keep reading the list they always read.

The headings and breaks are `aria-hidden` direct children of `#sessionTabs`, reconciled in place by `_syncTabTriageChrome()` after BOTH render paths, because a state change is an incremental pass and can still empty a group or fill a new one. Inside a header row tabs keep TAB order; a sorted rail ranks each section the way it ranks the flat rail. The header strip only wraps into rows on desktop, where `updateTabOverflowMode()` forces `tabs-auto-wrap`; the breaks only display in a wrapping strip, since a `flex-basis: 100%` break in a nowrap scroller would steal width.
⚠️ **Named groups win**: in the vertical rail with owner tab layouts (`_projectTabGroups()` non-null) triage is off and the grouped tree renders as before. With `tabGrouping: 'none'` nothing is left behind: no headings, no breaks, no inline order, no `tabs-triage` class. A stale cached mobile-overview.js degrades to the flat strip. The header strip only wraps into rows on desktop, where `updateTabOverflowMode()` forces `tabs-auto-wrap` while `tabs-triage` is on; the breaks only display in a wrapping strip, since a `flex-basis: 100%` break in a nowrap scroller would steal width. Tests: `test/tab-triage.test.ts`.
**By case.** Each case's tabs sit in one `.tab-cluster` box (`_renderTabClusters()`), in the order the case first appears in the tab order; membership is `_mobileOverviewCaseFor()` (longest case path that prefixes the working directory), else the directory, else the session alone. A box with two or more tabs is labelled (swatch, name, count) and its generated `w<n>-<case>` names drop the `-<case>`, which stays in the DOM in a `.tab-name-case` span only `.tabs-clusters` hides; a one-tab case gets only the swatch in the header strip; a web tab gets a box of its own. The colour is `--session-<colour>` by a stable hash of the case key (`CodemanTabClusters.colorFor()`), so nothing is stored. The rail and the sidebar draw every case as a labelled section; phones dissolve the boxes (`display: contents`) into the one chip row.
⚠️ **The boxes ARE a DOM grouping**, unlike by state, which is safe only because a tab changes case far less often than it changes state: `_tabClusterLayout().key` is the whole structure, and the incremental path rebuilds whenever it differs from the last full render's. The keyboard walk keeps boxes together (box index first, then computed order, since a sorted rail orders rows inside each box). Drag only reorders inside one box, as it only reorders inside one state group (`_isTabDropAcrossGroups()`).
**Ledger.** CSS only, on `.tabs-ledger` inside `@media (min-width: 768px)` and the header host: the flat list on an auto-fill column grid with equal cells, mono type and a 3px status bar (`--ledger-bar`: yellow for a waiting alert, red for an action alert or an error, muted for stopped, exited and web tabs) instead of the dot. ⚠️ It must not change the markup (pinned: the ledger's innerHTML equals classic's); the rail, the sidebar and narrower strips show the plain list.
With `classic` nothing is left behind: no headings, no breaks, no inline order, no boxes, no name split, no arrangement class. A stale cached mobile-overview.js degrades every grouping to the flat strip. Tests: `test/tab-triage.test.ts`, `test/tab-clusters.test.ts`.

⚠️ The clustered styles need the three elements contiguous, and the template keeps the classic order, so `applyHeaderStatsStyle()` MOVES `#connectionIndicator` into `#headerSystemStats` (first child) and `#planUsageChip` right after it, and `classic` moves them back to comment anchors it left at the template positions. Ids are unchanged, so every writer still finds them. ⚠️ The indicator joins the pill only while System Stats is shown: the pill is hidden with `display: none`, and the WS readout must not disappear with it.
⚠️ The extra parts (`.stat-spark`, `.connection-tile-label`/`-value`, `.pu-ring`, `.pu-meter`) are always rendered and hidden by default in styles.css, which is what keeps `classic` looking exactly as before.
