feat: expand agents (10), skills (20), and hooks (11) with profile system

Agents:
- Add YAML frontmatter (model, tools) to all 7 existing agents
- New agents: planner (opus), build-error-resolver (sonnet), loop-operator (sonnet)

Skills:
- search-first: research before building (Adopt/Extend/Compose/Build)
- verification-loop: full quality gate pipeline (Build→TypeCheck→Lint→Test→Security→Diff)
- strategic-compact: when and how to run /compact effectively
- autonomous-loops: 6 patterns for autonomous agent workflows
- continuous-learning: extract session learnings into instincts

Hooks:
- Profile system (minimal/standard/strict) via run-with-profile.sh
- config-protection: block linter/formatter config edits (standard)
- suggest-compact: remind about /compact every ~50 tool calls (standard)
- auto-tmux-dev: suggest tmux for dev servers (standard)
- session-save/session-load: persist and restore session context (Stop/SessionStart)

 ## Claude Code Hooks (`/.claude/hooks`)
 
+### Profile System
+
+Hooks use a profile system (`minimal|standard|strict`) controlled by `CLAUDE_HOOK_PROFILE` env var (default: `standard`).
+Individual hooks can be disabled via `CLAUDE_DISABLED_HOOKS` env var (comma-separated filenames).
+
+- `.claude/hooks/run-with-profile.sh` — profile gate wrapper for hooks.
+
+### Safety Hooks (always active)
+
 - `.claude/hooks/protect-files.sh` — blocks edits to `.env`, lock files, `.git/`, keys.
 - `.claude/hooks/bash-firewall.sh` — blocks destructive commands (`rm -rf /`, `git reset --hard`, etc.).
-- `.claude/hooks/post-edit-format.sh` — auto-formats files with Prettier after edits.
 - `.claude/hooks/audit-log.sh` — logs all Bash commands with timestamp to `audit.log`.
 - `.claude/hooks/commit-docs-reminder.sh` — reminds to check `status-update-checklist.md` before `git commit`.
-- `.claude/settings.json` — hooks configuration (also: Notification, SessionStart compact context).
+
+### Quality Hooks (standard+ profile)
+
+- `.claude/hooks/config-protection.sh` — blocks modifications to linter/formatter config files.
+- `.claude/hooks/suggest-compact.sh` — suggests /compact every ~50 tool calls.
+- `.claude/hooks/auto-tmux-dev.sh` — suggests tmux for long-running dev server commands.
+
+### Strict-Only Hooks
+
+- `.claude/hooks/post-edit-format.sh` — auto-formats files with Prettier after edits.
+
+### Session Persistence
+
+- `.claude/hooks/session-load.sh` — restores previous session context on SessionStart.
+- `.claude/hooks/session-save.sh` — saves session context (branch, files, commits) on Stop.
+- `.claude/sessions/` — session state storage directory.
+
+### Configuration
+
+- `.claude/settings.json` — hooks configuration (PreToolUse, PostToolUse, SessionStart, Stop, Notification).
