What

Creates switchyard daemon and installer for macos

Enables users to run single command and get switchyard configured with codex ootb.

simple config swap get codex.app working with switchyard.

Note moved menubar to #902

Summary by CodeRabbit

New Features
- Added macOS install and uninstall commands, including dry-run options. Installation configures Switchyard as a per-user background service and sets up Codex integration; uninstallation removes these and restores a saved direct Codex configuration when available.
Documentation
- Added the macOS commands to Makefile help output.
Known Issues
- Linux installation and uninstallation may stop before completing.

Navigate logical layers of code changes, visualize relationships, and explore their blast radius.

Walkthrough

The change adds shared shell helpers and Makefile targets for macOS installation, dry-run, and removal. The macOS scripts manage the server, LaunchAgent, and Codex configuration. Linux install and uninstall scripts still call helper functions that are no longer defined in those scripts.

Changes

Installer lifecycle

Layer / File(s)	Summary
Shared shell helpers and Linux script integration `scripts/common.sh`, `scripts/linux/common.sh`, `scripts/linux/install.sh`, `scripts/linux/uninstall.sh`, `tests/test_linux_install.py`	Adds shared shell operations and changes the Linux common script to source them. Linux install and uninstall still call helper functions removed from their scripts.
Wire and install the macOS server and Codex configuration `Makefile`, `scripts/macos/common.sh`, `scripts/macos/install.sh`, `tests/test_macos_install.py`	Adds macOS Makefile commands and installer logic for the server, LaunchAgent, Codex profiles, and routed configuration. Tests cover generated paths, configuration handling, and snapshot preservation.
Remove macOS integration and restore configuration `scripts/macos/uninstall.sh`	Adds removal of the LaunchAgent, Codex profiles, legacy profile block, and shell alias blocks. When a direct-config snapshot exists, the script restores it and backs up the current configuration.

Priority: ➖ Normal

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: 🟡 Moderate · up to 23a8b

Uninstalling can truncate a shell startup file or Codex config when a marker block is malformed. Reinstalling can silently discard Codex settings that the user added after the first install. Both are small fixes and should be made before merging.

_{A rabbit checks the launch agent’s trail,
Then routes the config without a fail.
A snapshot waits for rollback’s cue,
Shared helpers tidy each task through.
Linux scripts still call names now gone,
The rabbit spots the break at dawn.
It hops away with notes drawn.}

Review comments at @scripts/macos/install.sh:
- Line 88: Update the provider-table detection in the config transformation so
equivalent TOML headers, including quoted names and whitespace around the dot,
are replaced rather than retained before appending the provider. Validate the
generated TOML before offering the swapped config for installation.
- Around line 135-136: Escape the replacement ampersands in the Bash parameter
substitutions that encode XML entities, including the substitutions for
ampersands, less-than signs, and greater-than signs. This prevents Bash 5.2’s
patsub_replacement behavior from expanding them to the matched text and
preserves valid LaunchAgent XML.
- Line 266: Update the startup-file handling around the `for rc` loop to add a
managed `.bashrc` sourcing block to the applicable Bash login startup file,
preserving any existing startup behavior. Update the uninstall logic to remove
that same managed block.
