fix: clean up hash-based test directories in afterEach (#86)

Fixes bugbot issue: "Tests leak directories under home directory without cleanup"

The problem:
- Tests call the real getSessionsDir() which creates ~/.agent-orchestrator/{hash}/
  directories based on hashing the tmpDir path
- Each test run uses a new random tmpDir, creating a unique hash
- afterEach only cleaned up tmpDir, leaving orphaned directories in ~/.agent-orchestrator/
- These directories accumulated indefinitely

The fix:
- Added cleanup for hash-based directories in afterEach for all affected tests
- Uses getProjectBaseDir() to calculate the directory path
- Removes the hash-based directory before cleaning tmpDir
- All 61 tests pass (13 CLI + 48 core)

Files fixed:
- packages/cli/__tests__/commands/session.test.ts
- packages/core/src/__tests__/session-manager.test.ts
- packages/core/src/__tests__/lifecycle-manager.test.ts
