v0.7.0

Added

• Windows compatibility — cross-platform fixes so the package installs and runs on Windows:
  • Machine profile auto-detection: detect_machine_profile() reads the AI_HOST env var
    (falls back to socket.gethostname()) and maps sys.platform to a human-readable
    os_type ("windows", "macos", "linux"). ensure_machine_profile_registered()
    writes host_id and os_type to config.toml on first load_config() call — no
    manual config edit needed on first run.
  • Cross-platform root check: replaced os.getuid() == 0 with _is_root() helper
    (ctypes.windll.shell32.IsUserAnAdmin() on Windows, os.getuid() on POSIX).
  • Replaced POSIX find/rm pycache cleanup with Path.rglob("__pycache__") +
    shutil.rmtree.
  • is_cc_active_locally() uses psutil.process_iter() on Windows instead of pgrep.
  • Remote SSH transport (os.execvp("zsh", ...)) exits with a clear error message on
    Windows rather than crashing.
  • DEFAULT_CONFIG written with encoding="utf-8" (fixes UnicodeEncodeError on
    Windows CP1252 locales when the config contains non-ASCII characters).

Fixed

• iTerm2 pane-header drift on session re-attach (AI-CLI-59, final). The pane is
  now renamed by resolving the tmux session's live client tty at set-name time
  (tmux list-clients → tty → iTerm2 session with that tty), instead of a stored
  ITERM_SESSION_ID GUID. tty is 1:1 with a physical pane, so cross-session
  clobbering (two tmux sessions sharing one pane GUID) is now impossible. Removed
  the racy dual-GUID tracking: deleted _evict_iterm2_guid and
  _get_current_iterm_session_id, and the ITERM_SESSION_ID env-propagation from
  the launch/re-attach path. Panes display the engine-prefixed session id
  (c-sw-3 for Claude, g-… for Gemini/agy) so sessions stay visually
  distinguishable by engine.

Removed

• ai gemini command and the underlying gemini.py / research.py modules deleted.
  Migration: use a Gemini CLI tool directly for research queries.
• Contract tests for GeminiResult, AttemptLog, and run_gemini() in test_public_api.py
  removed (symbols no longer exist).

Changed

• ai spend gemini help text updated to clarify it reads historical local JSONL logs only.
