feat: meridia wiring integrations

* feat: scaffold evaluation harness foundation

* docs: add evaluation harness extension workstream note

* UX: add ChannelBroadcastCenter — unified messaging broadcast and channel management (openclaw#324)

* feat(evals): catalog schema + tool-reliability & agent-spawning scenarios (11 new cases)

- catalog.ts: ScenarioCatalog schema with category/difficulty grouping,
  CataloguedEvaluationCase type, filterCatalog, validateScenarioMetadata
- fixtures.ts: createDefaultCatalog, loadScenarios*, getCatalogStats CI loaders
- cases/hitl-escalation.ts: escalation-smoke + timeout-handling (ported from jerry/eval-scenario-schema)
- cases/memory-recall.ts: recall-context + path-traversal (ported from jerry/eval-scenario-schema)
- cases/tool-reliability.ts: 6 new deterministic scenarios
  - dispatch-success: happy-path tool invocation
  - dispatch-unknown-tool: graceful structured error on unknown name
  - retry-on-transient-failure: retry succeeds on nth attempt
  - max-retries-exhausted: retry gives up cleanly at limit
  - timeout-abort: AbortSignal propagation cuts execution early
  - result-schema-validation: validates ok/error result shape contracts
- cases/agent-spawning.ts: 5 new deterministic scenarios
  - basic-spawn-and-complete: child agent lifecycle + result accessible to parent
  - depth-limit-enforcement: spawn rejected beyond MAX_SPAWN_DEPTH=3
  - result-routing-to-requester: result delivered to correct session only
  - orphan-cleanup-on-parent-kill: recursive kill propagates to all descendants
  - parallel-completion-ordering: N concurrent agents collect without loss
- catalog.test.ts: 37 tests covering catalog build, filter, validation,
  per-category smoke runs (all 42 suite tests green)
- index.ts: updated exports for all new symbols

All scenarios: deterministic, no LLM calls, no external services.
Catalog now: 16 cases across 5 categories.

* UX: add ProviderRoutingPanel — AI provider routing and failover dashboard (openclaw#325)

* feat(evals): add JSONL export adapter for CI integration

- export-jsonl.ts: writeEvaluationJsonl writes each case as separate JSON line
- writeEvaluationJsonlSummary writes aggregate metrics in single line
- computeMetrics calculates per-suite, per-category, per-difficulty pass rates
- Supports append mode for incremental CI reporting
- 7 new tests covering path resolution, append, summary, and metrics

* feat(evaluation-harness): add WORKSTREAM.md and basic benchmark test

* feat(evals): add scenario catalog schema + 2 benchmark scenarios (HITL + memory) (openclaw#96)

- Add scenario catalog schema/metadata contracts in catalog.ts
- Add HITL benchmark scenarios (escalation + timeout handling)
- Add Memory path benchmark scenarios (context recall + path traversal)
- Add CI-friendly fixture loading in fixtures.ts
- Add comprehensive validation tests for catalog functionality
- Export all new types and cases from index.ts

Implements eh-002 with seed for eh-003 (5-scenario target)

* feat(evals): add tool-reliability benchmark scenario (4 cases) (openclaw#97)

* feat(evals): add scenario catalog schema + 2 benchmark scenarios (HITL + memory)

- Add scenario catalog schema/metadata contracts in catalog.ts
- Add HITL benchmark scenarios (escalation + timeout handling)
- Add Memory path benchmark scenarios (context recall + path traversal)
- Add CI-friendly fixture loading in fixtures.ts
- Add comprehensive validation tests for catalog functionality
- Export all new types and cases from index.ts

Implements eh-002 with seed for eh-003 (5-scenario target)

* feat(evals): add tool-reliability benchmark scenario (4 cases)

Adds the tool-reliability benchmark scenario to reach the 5-scenario target:
- tool-reliability.dispatch-smoke: basic tool dispatch structure validation
- tool-reliability.timeout-handling: tool timeout detection and handling
- tool-reliability.failure-recovery: fallback behavior on tool failure
- tool-reliability.result-validation: tool result structure validation

Wired through existing catalog + fixture loading utilities.
Updated tests to cover new scenarios.

eh-003 complete: 5-scenario target now met (was 4, added 4)
