ai-hist@0.3.4

Release Notes

Changed

• Make the public ai-hist command Rust-default for the user-facing CLI
  surface, including sync, show/context/session, stats, pack, resume,
  export/import, and tagging commands.
• Add a one-command installer that builds and installs deterministic ai-hist,
  ai-hist-rust, and ai-hist-python launchers without requiring users to run
  Cargo commands manually.
• Keep the legacy Python CLI as an explicit compatibility escape hatch via
  AI_HIST_CLI=python or ai-hist-python.

Fixed

• Align Rust default database path with XDG_DATA_HOME.
• Create legacy session metadata schema from Rust DB initialization.
• Set WAL mode from Rust DB initialization.
• Keep the legacy Python fallback importable on Python 3.9.6 by avoiding PEP
  604-only annotations.
