c85d2f9bc added 'server_error' and 'an error occurred while processing'
to the retryable message patterns to fix#3799 - the OpenAI streaming
server_error case where runtime fallback never fired. The package
layering refactor (2748009ff) moved model-error-classifier into
packages/model-core but dropped these two patterns during the move.
Restore both patterns at the matching position. packages/model-core
tests now pass on the server_error retryable assertion, and runtime
fallback once again retries the OpenAI streaming server_error envelope.
Move three pure helpers from src/shared/ into @oh-my-opencode/model-core so the package can stand alone without depending on plugin internals:
- buildModelCapabilitiesSnapshotFromModelsDev + fetchModelCapabilitiesSnapshot (models.dev normalization)
- parseModelSuggestion (cross-provider ProviderModelNotFoundError suggestion extraction)
- resolveActualContextLimit (Anthropic GA 1M context override)
Split provider-model-id-transform into two variants exposed by model-core:
- transformModelForProvider keeps the runtime dash to dot Anthropic rewrite used by the SDK
- transformModelForProviderDisplay preserves hyphenated Anthropic IDs so the installer writes registry-compatible model strings, fixing the ProviderModelNotFoundError fresh installs hit when the dotted form leaks into the config
src/shared/* and src/cli/provider-model-id-transform.ts collapse to re-export shims that point at the new core modules. Stale src/shared/{known-variants,model-capability-aliases,model-capability-guardrails,model-capability-heuristics}.ts re-export files plus the duplicated context-limit-resolver test are removed in favor of the canonical model-core copies.
Tests: bun test packages/model-core src/shared/model-capabilities-cache.test.ts src/cli/provider-model-id-transform.test.ts
- remove bundled snapshot dependency on src/generated in model-core
- make shared harness provide runtime bundled snapshot
- update guardrail and capability tests to pass explicit snapshot
