docs(tiles): no + in the tile header, owner decision 9

The spec records decision 9 and an as-built entry replacing the "+ / New
session in this case" one, and marks the target picture, the header line
and the + bullet as built without it. CLAUDE.md's header list, the
invariants' z-index line (the + menu's layer) and the wiki's Tile Grid
page (the header string, its table and the cap sentence) drop the +.

 **Split-pane sessions** (`showSplitButton`, header button, default OFF, desktop-only, per-device): a second live session ("Pane B") beside the active one, in a `TerminalTile` (terminal-tile.js; the picker, divider and auto-collapse stay in terminal-split.js) with its own xterm + WebSocket, resizable via a draggable divider. Pane B reconnects after a drop, sends input through the exactly-once queue over its own socket (`_registerInputSocket`), has clickable paths and image paste, and owns its geometry (no 40x10 floor, `zc` columns adopted, font changes call `tile.fit()`). ⚠️ Only typed input enters that persisted queue: xterm's query replies are dropped and focus/mouse reports go out ephemeral. ⚠️ App-level terminal actions find their pane through `_focusedPane()` (the terminal focused last), never `this.terminal`. Still plainer than the primary pane (no local-echo overlay, CJK IME or touch handlers) and NOT persisted across reloads. The tile grid (below) reuses `TerminalTile`, and the two are never open together. → [architecture-invariants#split-pane-sessions](docs/architecture-invariants.md#split-pane-sessions)
 
-**Tile grid** (`showTileGridButton`, header Tiles button + `Ctrl+Shift+G`, default OFF, desktop-only at 1180px, per-device; tile-grid.js, design `docs/tile-grid-plan.md`): 1 to 6 live sessions side by side (the cap is ONE constant, `TILE_GRID_MAX` in constants.js, owner decision; the layout table still covers 7 to 9, unreachable), each a `TerminalTile` with a header (state dot, name, menu, zoom, +, ×), laid out by count (`CodemanTileGrid`, constants.js) with draggable column/row dividers, zoom (tmux-style), an Attach overlay, and per-device persistence (`codeman:tile-grid`, ids only, restored INSIDE `handleInit` in place of the single-view select, so the main terminal never loads on that page load). While the grid is open the main terminal is PARKED: `activeSessionId` is the focused tile's session, and every main-terminal path that would write, fetch, resize or reconnect stands aside through `_tilesOwnTerminal()` (the WebGL long-task observer included). ⚠️ Every capture a tile fetches (initial, reconnect refresh, `{t:'r'}`, history pull) goes through ONE `TileLoadQueue` (concurrency 1, a deadline covering the body), because each is a synchronous tmux call on the server. ⚠️ Only a USER-initiated pick of a non-tiled session (or `leaveTiles`, a followed link) leaves the grid; an `auto` selection never collapses it, and every app-driven fallback (close, delete, restore) picks a tile. A caller of `closeTileGrid({ reselect: false })` must null `activeSessionId` before any `_cleanupPreviousSession`, or the parked terminal's stale content is saved as a snapshot. ⚠️ The grid and the split are never open together. ⚠️ Tile chords go through `tileShortcutFor` and are swallowed in every xterm key handler BEFORE the Shift+Enter gate; the toggle follows `showTileGridButton` (owner decision: OFF makes the chord inert, it passes through like any unbound key). ⚠️ The Tiles button's click and Ctrl+Shift+G are ONE function, `toggleTileGrid` (owner decision): they open the grid AT ONCE on `tileGridOpenSet` (constants.js: the stored grid, else an open split's two, else the tabs in order up to `_tileGridLimit()`, the active one focused), never a picker; the picker is on right-click (`oncontextmenu`). ⚠️ A divider drag reflows locally per frame and sends ONE resize per affected tile at pointer-up. ⚠️ Sessions Run from this tab join the open grid (`_joinTileGridFromRun`, called from `_ensureCreatedSessionVisible`); sessions created elsewhere never do. Such a tile connects before its pane exists, the server drops that resize and spawns at 120x40, and Run's own resize measures the parked terminal (nothing), so the chrome refresh calls `tile.paneStarted()` when the session's pid appears or changes. ⚠️ An agent that exited in a live pane (`paneExit`) cannot be re-attached in place (both attach routes refuse while the pane's tmux client runs, and say so in a 200 envelope): its tile shows the exit and points at Close session. ⚠️ zh-CN: every string the grid shows has its own `ZH_CN` entry or `translateDynamic` pattern in i18n.js (`test/tile-grid-i18n.test.ts` harvests them from the real code; add the entry with any new string), and a refresh compares with the last ENGLISH value it set, never the DOM, which holds the translation. → [architecture-invariants#tile-grid](docs/architecture-invariants.md#tile-grid)

 **Terminal touch gestures: link taps and text selection**: on touch devices xterm's linkifier and SelectionService never see the gesture, so both are driven explicitly (terminal-ui.js). ⚠️ A tap activates the link under it through the SAME provider as the hover linkifier (`_terminalLinkAtPoint`), synchronously inside `touchend` (keeps the user gesture `window.open` needs) and BEFORE any mouse report; the caret's logical line (`_tapIsOnCaretLine`) and TUI-owned rows (`_isActionableMobileTerminalTap`) keep their meaning. ⚠️ Gate on the caret line, never on tap intent (a shell calls every tap `'input'`). ⚠️ Long-press selects via xterm's public `select()`; keep the three guards: suppress the compat mouse pair after `touchend`, the bounded focus guard + `contextmenu` suppression for the platform long-press, and no closing `terminal.focus()` on phones.
