test: cover hostname title (#82) and tmux size-query (#80)

Browse Source 
Backfill the two regression gaps flagged on master after the recent
hostname-title and tmux-flicker fixes shipped without server-side
assertions.

* test/server-index-title.test.ts (8 tests) — exercises WebServer's
  index.html templating path: default os.hostname(), --title-hostname
  override, HTML-escape against `<script>`-style breakout, ampersand
  non-double-encoding, exact-once substitution, and byte-identical
  template-tail invariance.

* test/tmux-window-size-query.test.ts (15 tests) — mocks
  child_process.execFileSync and walks the helper through the
  browser-resize-between-attaches happy path, query-then-die race,
  zero/negative/empty/non-numeric output, plus argv-form/timeout
  assertions to lock down the no-shell-interpolation guarantee.

* src/session.ts — extracts the inline 14-line tmux size query into
  a named `queryTmuxWindowSize()` export so the test surface is a
  pure function. Behavior unchanged.

* src/web/public/notification-manager.js — Browser Notification API
  (layer 3) now uses `${this.originalTitle}: ${title}` so OS-level
  desktop pop-ups carry the same `codeman:<host>` prefix that the
  tab title and Web Push payloads already do, finishing the
  hostname plumb-through started in #82.

* CLAUDE.md, README.md — document the dual-CLI env-prefix discipline
  (CLAUDE_CODE_* vs OPENCODE_*), expand the xterm-zerolag-input
  duplication gotcha to mention the published-package side-effect,
  and note that the hostname prefix now applies uniformly to tab
  title, tab-flash, and OS notifications.

- **Package ≠ product name** — npm: `aicodeman`, product: **Codeman**. Release renames tags accordingly
- **Global regex `lastIndex`** — Shared `g`-flag patterns in loops must reset `lastIndex = 0` first, or use the `execPattern()` helper in `utils/regex-patterns.ts` (resets automatically)
- **`envOverrides` flow `CLAUDE_CODE_*` / `OPENCODE_*` env vars** — Set via `POST /api/sessions { envOverrides }`, stored on `Session._envOverrides`, exported by `tmux-manager.buildEnvExports()` at spawn time, persisted in `SessionState.envOverrides`. **Do NOT** write these to `<case>/.claude/settings.local.json` — that's the old path and creates UI/disk drift
- **Dual-CLI prefix discipline** — Codeman supports both Claude Code and OpenCode (`claude-cli-resolver.ts` / `opencode-cli-resolver.ts`); env-var prefix is CLI-specific (`CLAUDE_CODE_*` vs `OPENCODE_*`) and the allowlist in `schemas.ts` enforces this. When adding settings, decide which CLI(s) it applies to and gate the env export accordingly — don't blindly forward both prefixes
- **Zod `.optional()` rejects `null`** — accepts `undefined` only. When the frontend builds a request body with `JSON.stringify`, an explicit `null` field is preserved on the wire and fails validation with `INVALID_INPUT`. Convert `null` → `undefined` before stringifying (e.g. `field: value ?? undefined`), or declare the schema `.nullish()`. Real bugs caused: 0.6.4 (`durationMinutes` for ∞ respawn), and the same shape pattern hit `opusContext1mEnabled` in 0.6.3
- **`xterm-zerolag-input` is duplicated** — the local-echo overlay lives in BOTH `packages/xterm-zerolag-input/src/` (published package) AND inline inside `src/web/public/app.js` (runtime copy used by the web UI). Any change to overlay behavior MUST be applied to both, or dev and prod diverge. Always test on mobile after touching it.
- **`xterm-zerolag-input` is duplicated** — the local-echo overlay lives in BOTH `packages/xterm-zerolag-input/src/` (published to npm as a standalone library for external consumers — see README "Published Packages") AND inline inside `src/web/public/app.js` (runtime copy the web UI actually loads, since the page ships as plain JS without a bundler). Any change to overlay behavior MUST be applied to both, or dev and prod diverge — and a public API break in the package warrants a separate version bump for `xterm-zerolag-input` in the changeset. Always test on mobile after touching it.
**Import conventions**: Utils from `./utils`, types from `./types` (barrel), config from specific `./config/*` files.
