## Summary
Adds `tools/hangar` — a macOS desktop control panel for working on Fleet
locally: branch management, `fleet serve` orchestration, log tail, dev
MySQL backup/restore, `fleetctl`, GitOps, and `osquery-perf`, all in one
window.
Built with **Go + [Wails 3](https://v3alpha.wails.io)** — the backend is
plain Go (`os/exec`, `syscall`, goroutines) so Fleet engineers can
contribute to it; only the desktop shell is Wails. The `internal/`
packages are pure and unit-tested.
### History note
Hangar started as a Rust/Tauri app. It was ported to Go, and **the Go
port is now the canonical `tools/hangar`**. The original Rust/Tauri
implementation has been removed from the monorepo (preserved in a
standalone repo) — so although this branch's earlier commits add and
then replace the Rust app, the net diff is just the Go app at
`tools/hangar`. The bundle identifier is `com.fleetdm.fleet-hangar`,
matching the original app so existing settings carry over.
# Checklist for submitter
- [x] Input data is properly validated, `SELECT *` is avoided, SQL
injection is prevented (using placeholders for values in statements), JS
inline code is prevented especially for url redirects, and untrusted
data interpolated into shell scripts/commands is validated against shell
metacharacters.
- [x] Timeouts are implemented and retries are limited to avoid infinite
loops
> No `changes/` file: `tools/` is contributor tooling, not a
user-visible Fleet change. No DB migrations, no Fleet config settings,
no fleetd/orbit changes.
## Testing
- [x] Added/updated automated tests (Go unit tests across `internal/`,
including a path-traversal regression for backup deletion)
- [x] QA'd all new/changed functionality manually
## Test plan
- [x] `cd tools/hangar && task dev` launches the app (live-reload)
- [x] `task build` produces `bin/fleet-hangar`; `go test ./...` is green
- [x] First-run gate discovers a local Fleet clone and runs dep checks
- [x] Server tab can run the build chain and start `fleet serve`
- [x] Git tab branch search finds an older branch (e.g. a stale `qa-*`)
