Scarf's `MACOSX_DEPLOYMENT_TARGET` is `14.6` (Sonoma) on the main
`scarf` target, set in 86762ea. Sonoma support is intentional —
several users dogfood on macOS 14.x and we want to keep them on the
release channel. Yesterday's BUILDING.md and the long-stale
CONTRIBUTING.md statement both claimed macOS/Xcode 26.x as minimums,
which would have steered Sonoma contributors and users away from a
build that actually runs on their box.
Correct values:
- Runtime min: **macOS 14.6 (Sonoma)** — matches the deployment target.
- Build min: **Xcode 16.0** — needed for Swift 6 strict-concurrency
features the codebase uses.
Add a load-bearing-callout to BUILDING.md so future doc edits don't
silently raise the floor again.

Adds `scripts/local-build.sh` for unsigned command-line Debug builds
so contributors without an Apple Developer account can clone, build,
and run without provisioning gymnastics. The script:
- Detects arm64 / x86_64
- Verifies xcode-select, xcrun, xcodebuild are present
- Probes the Metal toolchain and offers an interactive install (gated
on `[[ -t 0 && -z "${CI:-}" ]]` — CI never gets prompted)
- Resolves Swift packages, builds Debug with signing disabled
- Optionally `ditto`s the result to /Applications/scarf.app on
explicit y/N
`BUILDING.md` documents prerequisites alongside the script. Existing
canonical Release universal CLI in README stays — `local-build.sh`
is an alternative for contributors, not a replacement for the
shipping build.
Cherry-picked from #76 with thanks to @unixwzrd. BUILDING.md's
prerequisites are corrected to match the actual deployment target
(macOS 26.2, Xcode 26.2+).
