Agentflow v8.4.9

Agentflow v8.4.9 uses installed skill paths for Codex, Claude, and Git guard hooks, migrates recognized older commands while preserving unrelated settings, and keeps worktree cleanup compatible with separately installed copies. Automatic notebook archiving now triggers at 500 lines or 768 KiB, while preserving the current round and pending inline answers.

This release also includes the earlier branch updates in 8.4.7 and 8.4.8: startup settings audits, verification of completed rounds in the Stop hook, and preservation of existing directory-specific ignore rules and project skill exceptions.

Installed skill symlinks still need their targets updated if the development checkout moves. Personal project hook repairs are not part of the public package. Native Windows looper support remains unavailable.

This publishes the missing GitHub Release and tag for the existing 8.4.9 public package, fixing issue #24. The tag identifies public commit 2007860; no package files were changed for this repair. See CHANGELOG.md for the version-by-version details.
