fed-sx-m2: Step 11a — Announce + Endorse genesis activity-types + 4 tests

Two new DefineActivity SX files in next/genesis/activity-types/
per design §13.5 / Step 11:

  announce.sx — Re-broadcast a peer's activity to followers.
    :object is the CID of the activity being announced.
    :schema requires :object to be a string.
    Followers see the Announce in their inbox; their projection
    decides whether to fetch the wrapped activity body.

  endorse.sx — Cross-actor signal on a target activity.
    :object is the target activity's CID; :kind is the
    endorsement variant (e.g. 'like', 'share').
    :schema requires both :object and :kind to be strings.
    Projections aggregate endorsements into counters / heat /
    ranking signals.

M1's Note object-type is unchanged — Create{Note{...}} is still
the publish path for short authored messages. The runtime-publish
demo (verb extensibility via Create{DefineActivity{...}} at
runtime) from M1 §9a continues to work; these files are the
genesis pre-shipped variants for v2 baseline so peers don't have
to negotiate verb definitions on first contact.

Manifest extended:
  :activity-types  3 -> 5 entries
  total genesis    34 -> 36 entries

Hardcoded count assertions bumped in:
  bootstrap_read.sh  (activity_types 3->5, first-section-count 3->5)
  bootstrap_load.sh  (activity_types 3->5)
  bootstrap_populate.sh (total 34->36, activity_types 3->5)
  bootstrap_start.sh (activity_types 3->5, total 34->36)

genesis_parse.sh +4 cases (head form + name for both files).
bootstrap_populate.sh internal sx_server timeout bumped
300s -> 600s to fit the larger genesis bundle.

61/61 in genesis_parse.sh, 15/15 in bootstrap_read.sh,
15/15 in bootstrap_load.sh, 14/14 in bootstrap_populate.sh,
12/12 in bootstrap_build.sh.
