refactor: Phase 2b — consolidate 28 modules into 14 packages

Complete the module consolidation planned in REFACTORING_PLAN.md:

Modules merged:
- work_orders/ + task_queue/ → swarm/ (subpackages)
- self_modify/ + self_tdd/ + upgrades/ → self_coding/ (subpackages)
- tools/ → creative/tools/
- chat_bridge/ + telegram_bot/ + shortcuts/ + voice/ → integrations/ (new)
- ws_manager/ + notifications/ + events/ + router/ → infrastructure/ (new)
- agents/ + agent_core/ + memory/ → timmy/ (subpackages)

Updated across codebase:
- 66 source files: import statements rewritten
- 13 test files: import + patch() target strings rewritten
- pyproject.toml: wheel includes (28→14), entry points updated
- CLAUDE.md: singleton paths, module map, entry points table
- AGENTS.md: file convention updates
- REFACTORING_PLAN.md: execution status, success metrics

Extras:
- Module-level CLAUDE.md added to 6 key packages (Phase 6.2)
- Zero test regressions: 1462 tests passing
