Replace oracle as the agent for council background tasks with a purpose-built
council-member agent. This avoids coupling to oracle's config/prompt and provides
proper read-only tool restrictions (deny write, edit, task, athena_council).
- New council-member-agent.ts with analysis-oriented system prompt
- Registered in agentSources (hidden from Sisyphus delegation table)
- Added to type system, Zod schemas, display names, tool restrictions
- Minimal model fallback (always overridden per council member at launch)
- Council orchestrator now launches members as council-member agent

Remove 9 files (913 lines) from the code-driven synthesis pipeline that
was superseded by the agent-driven approach in phases 6-8.
Phases 3/5 built: collectCouncilResults → formatForSynthesis →
buildSynthesisPrompt → formatFindingsForUser → buildDelegationPrompt.
Phases 6-8 replaced with: launch → background_output → Athena
synthesizes in conversation → switch_agent. The old pipeline was
never wired into runtime and all consumers were other dead code.
Also simplifies executeCouncil to return CouncilLaunchResult (task IDs
+ failures) instead of reading stale task status via collectCouncilResults.
Deleted: council-result-collector, synthesis-types, synthesis-prompt,
synthesis-formatter, findings-presenter, delegation-prompts (+ 4 tests).
Cleaned: CouncilMemberStatus, AgreementLevel, CouncilMemberResponse,
CouncilExecutionResult types from types.ts.
- Build pure prompt constructors with confirmed finding context and agreement levels
- Add BDD tests for fix/planning intent, question context, and single-finding edge cases
- implement createAthenaAgent with primary-mode model behavior and prompt metadata
- export Athena factory and metadata through athena and root agent barrels
- Add synthesis result contracts with agreement, provenance, and Athena assessment fields\n- Add synthesis prompt builder and council-response formatter with failure-aware provenance output
- Implement executeCouncil with parallel member launch and partial-failure tolerance
- Add result collection mapping and wire Athena exports with read-only athena tool restrictions
- Add council execution result and member response types for orchestration
- Implement provider/model parser for BackgroundManager-compatible model input
- Add shared council prompt builder and export new athena modules
- add AthenaOverrideConfigSchema so athena supports council plus standard override fields
- export athena schema/contracts and add root config tests for valid and invalid athena overrides
- switch schema generation to zod v4 toJSONSchema and regenerate JSON schema with athena council structure
