test: add unit tests for 8 untested modules (batch 3) (#191)
* test: add unit tests for 8 untested modules (batch 3)
New test files (143 tests total):
- tools/debug_helpers.py: DebugSession enable/disable, log, save, session info
- tools/skills_guard.py: scan_file, scan_skill, trust levels, install policy, structural checks
- tools/skills_sync.py: manifest read/write, skill discovery, sync logic
- gateway/sticker_cache.py: cache CRUD, sticker injection text builders
- gateway/channel_directory.py: channel resolution, display formatting, session building
- gateway/hooks.py: hook discovery, sync/async emit, wildcard matching
- gateway/mirror.py: session lookup, JSONL append, mirror_to_session
- honcho_integration/client.py: config from env/file, session name resolution, linked workspaces
Also documents a gap in skills_guard: multi-word prompt injection
variants like "ignore all prior instructions" bypass the regex scanner.
* test: strengthen sticker injection tests with exact format assertions
Replace loose "contains" checks with exact output matching for
build_sticker_injection and build_animated_sticker_injection.
Add edge cases: set_name without emoji, empty description, empty emoji.
* test: remove skills_guard gap-documenting test to avoid conflict with fix PR
