delta-cloud-208e 3d4b371e17 feat(updater): SEA install support for Claude Code 2.1.114+ (TDD + dual-critic APPROVE) ...

Adds install_sea_release() to uclaude_updater.py — dispatches by release
type from releases/v<VER>/, supporting both legacy cli.js and new SEA layout.

Production-hardened (after 2 rounds of dual-critic FIX):
- Pre-verify source sha256 BEFORE touching install_root (fail-fast)
- Atomic copy via _atomic_copy_with_fsync: write to .new, fsync, rename,
  then fsync parent dir (POSIX durability)
- .new cleanup on any exception (no orphan files)
- fcntl.flock on <install_root>/.uclaude-update.lock (concurrent run safe)
- Backup existing → .bak.<TIMESTAMP> before overwrite
- Post-install sha256 verify; rollback from backup on mismatch
- Atomic symlink update (tmp_link + os.replace)

cmd_update dispatches:
- detect_release_type → "sea" / "cli_js" / None
- "sea" → install_sea_release with /usr/lib/node_modules root + /usr/bin/claude symlink
- "cli_js" → existing legacy install_cli_js (preserved)
- None → fail with clear error

Updated:
- claude/uclaude_updater.py — +138 lines (install_sea_release + helpers)
- claude/releases/index.json — latest=2.1.119, +v2.1.119 entry (sea_binary)

Tests: 11/11 GREEN (claude/tests/test_sea_install.py — new file)
Dual critic: gpt-5.4 + GLM 5.1 both APPROVE (round 3 final)
