feat(v0.6): Project Manager — repo discovery + Projects panel + tab wiring
Home screen gains a Sessions↔Projects segmented control. The Projects view
discovers the host's git repos and, on click, opens a tab named after the
repo, spawned in the repo dir, auto-running `claude` (1:N sessions per project).
Backend (P2/P4):
- src/http/projects.ts — parseGitHead + buildProjects(cfg, liveSessions):
depth-capped BFS for .git (skips node_modules/dotdirs/symlinks, stops
descending at a repo), .git/HEAD branch parse, rate-limited `git status`
dirty check (execFile, no shell, 2s timeout, concurrency 8), merge of
~/.claude/projects cwds (reuses history.listSessions), cwd-prefix session
merge (fresh each call), TTL discovery cache with in-flight dedup.
- src/server.ts — read-only GET /projects (no Origin guard, []-fallback).
Frontend (P5/P6):
- public/projects.ts — mountProjects: 1:N cards (branch chip, dirty dot,
session rows, "+ start claude here"), live search, localStorage favourites;
pure helpers extracted for unit tests.
- public/tabs.ts — openProject (#n suffix for dup names, sends 'claude\r'),
countOpenWithTitlePrefix, Sessions↔Projects home toggle (updateHomeView).
- public/style.css — Projects panel + .home-seg control styles.
Config (P3, hardened): PROJECT_ROOTS/SCAN_DEPTH/SCAN_TTL/DIRTY_CHECK already
added; this commit adds fail-fast rejection of relative PROJECT_ROOTS.
Review hardening (4 confirmed HIGH + boundary validation):
- carriage-return fix so claude auto-executes (A3); seg-control z-order;
parallelised history merge; concurrent-cache-miss dedup.
- normalizeProject guards the /projects response; getFavs filters non-strings.
Tests: +57 (398 total). Backend src/http/projects.ts 93.4%, config.ts 98%.
Verified: both typechecks clean, full suite green, build:web OK, coverage
≥80×4, real-browser smoke (83 repos, branch/dirty correct, click→claude tab).
