* fix(security): properly test Windows ACL audit for config includes
The test expected fs.config_include.perms_writable on Windows but
chmod 0o644 has no effect on Windows ACLs. Use icacls to grant
Everyone write access, which properly triggers the security check.
Also stubs execIcacls to return proper ACL output so the audit
can parse permissions without running actual icacls on the system.
Adds cleanup via try/finally to remove temp directory containing
world-writable test file.
Fixes checks-windows CI failure.
* test: isolate heartbeat runner tests from user workspace

* feat: skip heartbeat API calls when HEARTBEAT.md is effectively empty
- Added isHeartbeatContentEffectivelyEmpty() to detect files with only headers/comments
- Modified runHeartbeatOnce() to check HEARTBEAT.md content before polling the LLM
- Returns early with 'empty-heartbeat-file' reason when no actionable tasks exist
- Preserves existing behavior when file is missing (lets LLM decide)
- Added comprehensive test coverage for empty file detection
- Saves API calls/costs when heartbeat file has no meaningful content
* chore: update HEARTBEAT.md template to be effectively empty by default
Changed instruction text to comment format so new workspaces benefit from
heartbeat optimization immediately. Users still get clear guidance on usage.
* fix: only treat markdown headers (# followed by space) as comments, not #TODO etc
* refactor: simplify regex per code review suggestion
* docs: clarify heartbeat empty file behavior (#1535) (thanks @JustYannicc)
