midge v0.2.1 — first-run reliability fixes

Maintenance release. If you hit an install or load problem on v0.2.0, update to this release — it fixes several first-run issues.

Fixes

• Model load no longer hangs silently. The engine now prints load progress (# loading, # mapped experts (N GB)) and the client waits for readiness with a bounded, correct timeout — a stalled or misconfigured load fails with a clear message instead of hanging forever.
• midge search no longer crashes. It previously raised a TypeError against newer huggingface_hub; it now adapts to the installed version and degrades gracefully offline.
• Friendly errors on a fresh machine. midge --help and every command now print a clear "missing package — run pip install -r requirements.txt" message on a dependency-free Python instead of a traceback.
• Optional-dependency test suites skip cleanly (make test-mlx, make test-server) when mlx/openai aren't installed, instead of erroring.
• Added SUPPORT.md and an issue template with load-hang triage and the exact startup lines to expect.

Verified

AddressSanitizer + UBSan clean; clang + strict gcc builds pass; fresh-clone install.sh in a bare venv; C, MLX, and UI suites green in CI; the convert→load→chat flow shows progress with no hang. Regression tests added for the search crash and the bare-Python guard.

See SUPPORT.md if you hit trouble.
