Replace isExtendedThinkingModel() model-name check with hasSignedThinkingBlocksInHistory()
which scans message history for real Anthropic-signed thinking blocks.
Content-based gating is more robust than model-name checks — works correctly
with custom model IDs, proxied models, and new model releases without code changes.
- Add isSignedThinkingPart() that matches type thinking/redacted_thinking with valid signature
- Skip synthetic parts (injected by previous hook runs)
- GPT reasoning blocks (type=reasoning, no signature) correctly excluded
- Add comprehensive tests: signed injection, redacted_thinking, reasoning negative case, synthetic skip
Inspired by PR #2653 content-based approach, combined with redacted_thinking support from 0732cb85.

- Registry-based model family detection (provider-agnostic)
- Variant and reasoningEffort ladder downgrade logic
- Three-tier resolution: metadata override → family heuristic → unknown drop
- Comprehensive test suite covering all model families
Add support for object-style entries in fallback_models arrays, enabling
per-model configuration of variant, reasoningEffort, temperature, top_p,
maxTokens, and thinking settings.
- Zod schema for FallbackModelObject with full validation
- normalizeFallbackModels() and flattenToFallbackModelStrings() utilities
- Provider-agnostic model resolution pipeline with fallback chain
- Session prompt params state management
- Fallback chain construction with prefix-match lookup
- Integration across delegate-task, background-agent, and plugin layers
Scoped packages like @scope/pkg were truncated to just 'pkg' because
basename() strips the scope prefix. Fix:
- Detect scoped packages (starting with @) and find version separator
after the scope slash, not at the leading @
- Return full scoped name (@scope/pkg) instead of calling basename
- Add regression test for scoped package name preservation
The test name claimed it exercised RETRYABLE_ERROR_PATTERNS directly,
but classifyErrorType actually matches 'payment required' via the
quota_exceeded path first. Rename to 'detects payment required errors
as retryable' to accurately describe end-to-end behavior.
- Gate semantic detection on promise === 'DONE' in both transcript and
session message paths to prevent false positives on VERIFIED promises
- Restrict transcript semantic fallback to assistant/text entries only,
skipping tool_use/tool_result to avoid matching file content
- Add regression test for VERIFIED promise not triggering semantic detection
Use port 0 fallback when findAvailablePort fails, read the actual bound
port from server.port. Tests refactored to use mock server when real
socket binding is unavailable in CI.

Previously, when an explicit model was configured, the agent name was
omitted to prevent opencode's built-in agent fallback chain from
overriding the user-specified model. This removes that conditional logic
and always passes the agent name alongside the model. Tests are updated
to reflect this behavior change.
