Worktree feat configurable output guard (#305)

* feat: configurable judge rules with dedicated admin tab

Externalize heuristic intent validation rules and output guard patterns
from hard-coded module constants into the storage abstraction with full
admin UI CRUD. Introduces a dedicated Judge tab in the admin panel that
consolidates all judge configuration (scalar settings, heuristic rules,
output guard patterns) under a single admin.judge permission scope.

- Add heuristic_rules and output_guard_patterns tables (migration 033)
- Add RuleRegistry with thread-safe merge of built-in + DB rules
- Refactor output_guard.py patterns into structured OutputGuardPatternDef
- evaluate_heuristic() and evaluate_output() accept optional rules/patterns
- IntentJudge resolves model aliases via ModelRegistry
- 15 admin API endpoints under /api/admin/judge/ with regex validation
- Judge tab with Settings, Heuristic Rules, and Output Guard sub-panels
- Filter judge.* settings from generic Settings tab
- ConfigStore.storage public property for backend access

* fix: align Judge tab with admin panel design system

- Replace raw <table> with grid-based admin-row/admin-colheaders pattern
- Replace dynamic innerHTML modals with static overlays using focus traps
- Replace confirm() with styled showConfirmModal()
- Replace inline badge styles with scope-badge classes
- Add mobile responsive breakpoints for Judge tab grids

* fix: Judge tab accessibility and polish

- Extract sub-section switcher inline styles to CSS classes
- Add focus-visible outline and reduced-motion support
- Add tab button IDs and fix aria-labelledby on tabpanels
- Add tabindex roving and arrow key navigation for sub-tabs
- Add role=list and aria-live to table containers
- Replace status text with scope-badge classes for scannability

* fix: address CodeQL and Copilot review feedback

- Remove unused validation constants from rule_registry.py (CodeQL)
- Return MappingProxyType from output_patterns for immutability
- Fix ThreadPoolExecutor shutdown(wait=False) to prevent hangs
- Use separate _VALID_OG_RISK_LEVELS (no "critical") for output guard
- Pass pattern_flags to regex validation in update endpoint
- Chain redactions in configurable mode (compose pattern + complex)
- Initialize RuleRegistry on console app.state
- Fix test fixtures to use valid enum values (approve/review/deny)

* fix: use Mapping type for evaluate_output patterns param (mypy)

+stored in the ``heuristic_rules`` and ``output_guard_patterns`` tables.

+  - DB row with builtin=0 → new custom rule
+  - No DB row → built-in used as-is
