FI-WP-0005 T01-T03: owner declaration, publication decision, egress hosts.

- Owner declaration for the profiled fi-daily-research-brief (proposed):
  inputs, single-commit briefs/** grant, fast-forward-only publication,
  quality rules, model requirements without env selection, completion
  evidence and rollback pins.
- Decision: origin publication is a typed grant on the run, not an
  executor default.
- docs/sources-egress.yaml: 17 exact host:443 entries for the sandbox,
  tested for sand-boxer format and drift against the prose allowlist.
