v0.3.47 — Clearer test selection and safer discovery

Why this matters

An empty test selection used to look like a clean run, and a cold Unity project could be searched before its requested test assembly was ready. That made “nothing ran” easy to confuse with “everything passed”.

What this gives you

• A test filter that selects nothing now reports test_filter_no_match instead of looking like a successful empty run.
• Explicit test assemblies are refreshed and loaded before their tests are searched, making cold-project discovery more dependable.
• Long non-Unity command lines no longer risk a slow regular-expression scan.
• Package self-tests leave an active bridge run alone and clean up temporary test scenes.

Validation

• Unity package checks: EditMode 16/16, PlayMode 5/5, and a cold-discovery test 1/1.
• Host regression: 466 tests passed.
• Public site checks: 42/42.
