feat: add list/status/resume/close subcommands to /gsd-quick and /gsd-thread (#2159)
* feat(2155): add list/status/resume subcommands and security hardening to /gsd-quick - Add SUBCMD routing (list/status/resume/run) before quick workflow delegation - LIST subcommand scans .planning/quick/ dirs, reads SUMMARY.md frontmatter status - STATUS subcommand shows plan description and current status for a slug - RESUME subcommand finds task by slug, prints context, then resumes quick workflow - Slug sanitization: only [a-z0-9-], max 60 chars, reject ".." and "/" - Directory name sanitization for display (strip non-printable + ANSI sequences) - Add security_notes section documenting all input handling guarantees * feat(2156): formalize thread status frontmatter, add list/close/status subcommands, remove heredoc injection risk - Replace heredoc (cat << 'EOF') with Write tool instruction — eliminates shell injection risk - Thread template now uses YAML frontmatter (slug, title, status, created, updated fields) - Add subcommand routing: list / list --open / list --resolved / close <slug> / status <slug> - LIST mode reads status from frontmatter, falls back to ## Status heading - CLOSE mode updates frontmatter status to resolved via frontmatter set, then commits - STATUS mode displays thread summary (title, status, goal, next steps) without spawning - RESUME mode updates status from open → in_progress via frontmatter set - Slug sanitization for close/status: only [a-z0-9-], max 60 chars, reject ".." and "/" - Add security_notes section documenting all input handling guarantees * test(2155,2156): add quick and thread session management tests - quick-session-management.test.cjs: verifies list/status/resume routing, slug sanitization, directory sanitization, frontmatter get usage, security_notes - thread-session-management.test.cjs: verifies list filters (--open/--resolved), close/status subcommands, no heredoc, frontmatter fields, Write tool usage, slug sanitization, security_notes

For each thread file found:

Apply filter for LIST-OPEN (show only status=open or status=in_progress) or LIST-RESOLVED (show only status=resolved).
