Initial commit: matchmaking-v2 on-demand multi-board job-search agent

On-demand Scout service (replaces the nightly aggregator):
- FastAPI agent-mesh service; card name "matchmaking-service" (HTTP /a2a/tasks
  + Redis-stream worker matching the sibling-service pattern)
- run_search: parallel multi-board sweep (Naukri/blackfalcondata + Foundit +
  LinkedIn), city-filtered at the board, cheapest-per-result first
- per-board adapters + normalizers -> ScoutJob with rich read-only details and
  offsite apply links; recall mode + MVQ guard
- result cache for dev replay ($0); per-board cost knobs; retry-on-5xx
- research/: engine design, board cost economics, India-actor shortlist, POC
