LaunchInput.temperature and LaunchInput.permission were accepted and
passed through the council orchestrator but never forwarded to the
actual promptAsync API call (SDK doesn't support per-request temperature
or permission). Remove the dead fields, the unused AthenaConfig
interface, and update tests/docs/schema accordingly.
- Forward temperature and permission through council-launcher to background manager
- Add LaunchInput.temperature and LaunchInput.permission to background-agent types
- Extract session guard with 5-minute timeout to prevent stale council locks
- Make council optional in AthenaOverrideConfigSchema for partial user overrides
- Support member lookup by both name and model ID in filterCouncilMembers
- Add provider/model-id format validation to CouncilMemberSchema
- Fix findings-presenter group header to show finding count instead of first finding's reporter count
- Add BDD coverage for valid and invalid Athena council configs
- Include inference and optional-field behavior assertions for CouncilMemberSchema
- Keep RED phase failing until schema implementation is added
