Yaojia Wang 9a6150c355 feat(v0.3): H3 — remote approve/reject (no typing)
- types/protocol: ClientMessage approve/reject; ServerMessage status.pending
- server: POST /hook/permission HELD until the client decides; approve/reject
  ws messages resolve it with {hookSpecificOutput.decision.behavior allow|deny};
  5-min timeout + release-on-disconnect fall back to Claude's own prompt
- manager.handleHookEvent threads pending flag
- setup-hooks: PermissionRequest uses the held curl (writes decision to stdout);
  status events stay fire-and-forget
- FE: terminal-session approve()/reject() + pending state; tabs approval banner
  (Approve/Reject) for the active tab's held request
- Tests: protocol approve/reject; integration ⑧ held→approve→allow. 207 green.
- Browser-verified: banner 'Claude wants to use Bash' → Approve → resolves allow.

/**
* scripts/setup-hooks.mjs — install/remove web-terminal's Claude Code hooks (H2).
*
* Adds `command` hooks to ~/.claude/settings.json that POST each hook event to
* the web-terminal server so it can show live Claude status per tab. The command
* is an inline curl that uses two env vars the server injects into each spawned
* shell: $WEBTERM_HOOK_URL (the server's /hook URL, with the right port) and
* $WEBTERM_SESSION (which tab). Outside web-terminal those vars are unset, so
* curl no-ops (|| true) — the hooks are harmless in normal terminals.
*
* Usage:
* node scripts/setup-hooks.mjs # install (idempotent)
* node scripts/setup-hooks.mjs --remove # uninstall
*
* Backs up settings.json to settings.json.webterm-bak before writing.
