On Windows, os.homedir() uses USERPROFILE env var instead of HOME.
Tests that override HOME to a temp dir must also set USERPROFILE for
the session-manager, session-aliases, and session-start hook tests
to find files in the correct directory.
Bug fixes:
- utils.js: prevent duplicate 'g' flag in countInFile regex construction
- validate-agents.js: handle CRLF line endings in frontmatter parsing
- validate-hooks.js: handle \t and \\ escape sequences in inline JS validation
- session-aliases.js: prevent NaN in date sort when timestamps are missing
- session-aliases.js: persist rollback on rename failure instead of silent loss
- session-manager.js: require absolute paths in getSessionStats to prevent
content strings ending with .tmp from being treated as file paths
New tests (164 total, up from 97):
- session-manager.test.js: 27 tests covering parseSessionFilename,
parseSessionMetadata, getSessionStats, CRUD operations, getSessionSize,
getSessionTitle, edge cases (null input, non-existent files, directories)
- session-aliases.test.js: 40 tests covering loadAliases (corrupted JSON,
invalid structure), setAlias (validation, reserved names), resolveAlias,
listAliases (sort, search, limit), deleteAlias, renameAlias, updateAliasTitle,
resolveSessionAlias, getAliasesForSession, cleanupAliases, atomic write
Also includes hook-generated improvements:
- utils.d.ts: document that readStdinJson never rejects
- session-aliases.d.ts: fix updateAliasTitle type to accept null
- package-manager.js: add try-catch to setProjectPackageManager writeFile
