Fixes from multi-model council audit (7 members, 19 findings, 9 selected):
- Use parseModelString() for cross-provider Anthropic thinking config (#3)
- Update stale AGENTS.md athena directory listing (#4)
- Replace prompt in appendMissingCouncilPrompt instead of appending (#5)
- Extract duplicated session cleanup logic in agent-switch hook (#6)
- Surface skipped council members when >=2 valid members exist (#9)
- Expand fallback handoff regex with negation guards (#11)
- Remove dead council-member agent from agentSources and tests (#12)
- Make runtime council member duplicate check case-insensitive (#14)
- Fix false-positive schema tests by adding required name field (#18)
Use parsed.providerID/modelID in council member description instead of
raw model string (eliminates dead variable). Track skipped members with
reasons and surface them in the missing-council guard prompt so users
see why their council failed to register.
- Add council config guard prompt: when Athena has no valid council members,
inject a STOP instruction telling the user how to configure council members
instead of failing messily with generic agents
- Make council member 'name' field mandatory (was optional with auto-naming)
- Remove humanizeModelId and UPPERCASE_TOKENS — no more fragile auto-naming
- Replace throw on duplicate names with log + skip (graceful degradation)
- Update schema, types, tests (87 pass), and documentation
Three registration improvements: gate council member registration on Athena enablement, throw on duplicate council member keys instead of silent overwrite, and disable council mode when valid members drop below 2 after model parsing.

Each council member from config is now registered as a named agent (e.g. 'Council: Claude Opus 4.6') via registerCouncilMemberAgents(). Adds humanizeModelId() to derive friendly display names from model IDs. Athena's prompt gets the member list appended so it can call task(subagent_type=...) for each.
