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)
