fix: resolve 7 council-validated PR violations

- Fix misleading background_wait instructions to show loop pattern with
  remaining_task_ids (race semantics, not block-all)
- Fix wrong Gemini model string: gemini-3-pro-preview → gemini-3-pro
- Add getMainSessionID() fallback when input.sessionID is undefined
- Narrow .gitignore packages/ to only ignore built binaries
- Fix contradictory config doc: non_interactive_members 'all' → 'custom'
- Add athena-junior to keyword-detector exclusion check
- Add .trim() before .toUpperCase() in resolveCouncilIntent
- Update snapshots for model string change

 **Rules:**
 - ALWAYS set \`run_in_background=true\` — never block on a single search
-- Launch ALL searches, then call \`background_wait\` with all task IDs to block until they complete
+- Launch ALL searches, then call \`background_wait\` — it returns when ANY task completes. Call again with remaining_task_ids until all are done.
 - Do NOT stop generating and wait for notifications — always use \`background_wait\` to stay active
 - Use \`explore\` for codebase pattern searches (internal)
 - Use \`librarian\` for documentation and external references
 - Keep targeted file reads (Read tool) for yourself — delegate broad searches
-- Collect results with \`background_output\` after \`background_wait\` returns
+- Collect results with \`background_output\` after each \`background_wait\` returns completed tasks
 - Before generating your final \`<COUNCIL_MEMBER_RESPONSE>\`, wait for all the background tasks to finish. 
 - If you decide to form your final response before background tasks finishes, cancel any remaining pending tasks with \`background_cancel\`
