v2.4.0 — Shell Toggle, Slow Log, Self-Update

Features

• lean-ctx-on / lean-ctx-off / lean-ctx-status — Shell toggle functions installed by lean-ctx init --global. Switch between compressed AI mode and human-readable output without restarting the shell. Set LEAN_CTX_ENABLED=0 to disable by default (#13)

• Slow query log — Commands exceeding slow_command_threshold_ms (default: 5000ms) are automatically logged to ~/.lean-ctx/slow-commands.log. New lean-ctx slow-log [list|clear] command to inspect or clear the log (#14)

• lean-ctx update — Built-in self-update command. Fetches the latest release from the GitHub API, downloads the appropriate binary archive for the current platform (macOS arm64/x86_64, Linux x86_64/aarch64, Windows x86_64), and safely replaces the running binary. lean-ctx update --check checks for updates without installing (#15)

Fixes

• excluded_commands now enforced — Commands listed in ~/.lean-ctx/config.toml under excluded_commands now actually bypass compression (#10)

• Windows Git Bash shell flag — Correctly assigns -c for POSIX-style shells on Windows instead of /C (cmd.exe only). Fixes the /C: Is a directory error (#7, #11)
