fix(schema-pack): restore v2 capability parity + derive bundled-pack list + calibration holder config

- #2109: extract-timeline-from-meetings matches frontmatter.legacy_type='meeting'
  in both SQL sites so unify-types-migrated (gbrain-base-v2) brains keep the
  feature alive; pre-unify type='meeting' behavior unchanged.
- #2117: gbrain-base-v2 declares phases: [extract_atoms] and ports v1's
  founded/works_at/invested_in inference regexes so extract_atoms is no longer
  pack-gated off and extract-ner no longer returns pack_unavailable on the
  bundled default pack. (attended's page_type:meeting inference deliberately
  not ported — v2 declares no meeting type; lint would reject it.)
- #1726 (A): list_schema_packs derives from the exported BUNDLED_PACKS registry
  in load-active.ts instead of a frozen 2-of-7 literal.
- #1726 (B): new calibration.user_holder config key (symmetric with
  emotional_weight.user_holder) resolved by the calibration_profile phase, the
  gbrain calibration CLI, and the get_calibration_profile op; explicit
  holder param still wins; 'garry' stays the fallback.
