feat: add uninstall.sh to reverse setup.sh

[tripathiprateek]

Summary

• Adds uninstall.sh that cleanly reverses everything setup.sh creates
• Removes MLX venv, server dir, desktop launcher, phone/iMessage scripts
• Optionally deletes downloaded models (--keep-models flag to preserve them)
• Leaves shared system tools untouched (Homebrew, Python, Claude CLI)
• Kills running MLX server on :4000 if active

Usage

bash uninstall.sh              # full cleanup including models
bash uninstall.sh --keep-models # keep downloaded model weights

Test plan

• Run bash setup.sh on a fresh Mac, verify artifacts created
• Run bash uninstall.sh --keep-models, verify everything removed except models
• Run bash uninstall.sh on a setup with models, verify models deleted
• Run bash uninstall.sh with no prior setup, verify graceful no-ops

Thanks for the PR — the structure and --keep-models flag are both good calls. A few things before this can merge:

Blocker: phone scripts aren't necessarily this project's to delete

setup.sh copies the iMessage scripts into ~/.claude/ from scripts/ in this repo. But plenty of users already have those scripts in ~/.claude/ from other sources (they're part of a broader personal iMessage/remote-control system, not strictly tied to this project). Right now uninstall.sh will nuke them regardless — that's a foot-gun.

Options:

• Cheapest: prompt before deleting (Delete iMessage scripts from ~/.claude/? [y/N]) with a default-no.
• Better: only delete if the file in ~/.claude/<name> is byte-identical to scripts/<name> in this repo (i.e. setup.sh put it there). cmp -s works fine for this.

set -e should come off

For an uninstaller you want best-effort cleanup. If any rm trips (permission, race, whatever), set -e aborts the script and leaves the rest of the state half-removed. Drop it, or trap errors and keep going.

Model deletion should confirm by default

Deleting 18-75 GB silently is a lot. Suggest flipping the default: require --delete-models (or prompt interactively) and treat --keep-models as the default. At minimum, prompt unless -y.

Hardcoded model list will drift

If setup.sh adds or renames a model tier, the uninstaller silently skips it. Could glob (models--mlx-community--Qwen*, models--divinetribe--gemma*) or list dirs matching a known prefix set. Minor — but it'll bite within a release or two.

Missed: scripts/config.sh

setup.sh copies config.example.sh → scripts/config.sh inside the repo on first run. Worth removing that too (or noting it's preserved since it may have user edits).

Test plan

The checkboxes are empty — have you actually run both directions on a fresh Mac? That'd be the quickest way to surface whatever else I missed.

Happy to merge once the phone-scripts behavior is safe and set -e is out. The rest is polish.
