Prerelease: no

Release notes:

New features

• `cog doctor` command. Diagnose common Cog setup issues, check configuration, and verify that everything is working correctly. Run cog doctor to validate your environment. (#2923)

Improvements

• Static schema generation is now the default. Cog now generates prediction schemas statically from your predictor's type annotations rather than importing and inspecting the Python code at build time. This makes builds faster and more reliable. Use COG_LEGACY_SCHEMA=1 to opt out if you encounter issues. (#2950)
• Test harness improvements. The Cog integration test harness now runs tests in parallel and provides better error reporting. (#2944)

Bug fixes

• Separate-weights builds with r8.im image names work correctly. Schema validation no longer fails when building with separate weights and using r8.im/... image names. (#2954)
• Static schema generation handles more edge cases. Fixed issues with certain type annotation patterns in static schema generation. (#2948)
• `Secret = Input(default=None)` is treated as optional. Secret inputs with None defaults are now correctly identified as optional in the generated schema. (#2949)
