chore(ai): refresh default model catalog

[murongg]

Summary

• refresh the built-in model catalogs and fresh-install defaults for current providers
• keep the previous built-in model entries available instead of removing them
• append missing built-in models to recognized legacy settings while preserving stored order, custom models, edited entries, and selected defaults

Why

Provider model catalogs have moved forward, but existing settings remain user-owned and should not be replaced during normalization.

Validation

• pnpm --filter @markra/providers test passed (10 files, 36 tests)
• pnpm --filter @markra/providers build passed
• pnpm --filter @markra/providers typecheck:test passed
• pnpm --filter @markra/app test passed (132 files, 1501 tests)
• pnpm --filter @markra/app build passed
• pnpm --filter @markra/app typecheck:test passed
• git diff --check passed

Risk

• fresh settings use the refreshed provider defaults
• existing selected defaults are preserved when their models still exist
• custom providers and user-curated partial model lists remain unchanged; recognized legacy built-in lists receive additive-only model updates
