Family server, slice 1 (row 204, protocol RE b039, review b043).

What it does

• New family_members table (db/src/family.rs). Each row holds the character's senior, the rep counters, and the leader's precepts.
• Family window (INFO + privilege list): sent on entering the game and on OPEN_FAMILY. The client sends no family request other than OPEN_FAMILY/OPEN_FAMILY_PEDIGREE until INFO has arrived. The privilege list is empty for now.
• Taking a junior (ADD_FAMILY / ACCEPT_FAMILY):
  • The server gives b039's refusals: not found/offline, another map, below level 10, not lower, more than 20 levels apart, already has a senior, same family, busy (another senior is asking), and the 1000-generation limit.
  • A second ask from the same senior while the card is up is ignored, because the client would decline the second card.
  • A yes is checked again (map and levels) and then made in a locked transaction.
  • On success the senior gets JOIN_REQUEST_RESULT, the junior gets JOIN_ACCEPTED, and the senior plus the junior's whole branch get INFO again.
• Family Tree (OPEN_FAMILY_PEDIGREE): sends FAMILY_CHART_RESULT filling the window's 11 slots:
  • the leader, two seniors, self, sibling, juniors, and juniors' juniors;
  • head counts for the family, the seniors, and each junior's branch;
  • live online state, level, job and map from the world directory.
• Login notices: the senior and juniors hear when a relative logs in or out. A channel change is held for the grace period, like guilds.
• Two stale net unit tests on master fixed: the world route count (stale since the RPS server) and the default keymap (stale since party search's O key).

Not yet

• Separating from a senior or junior.
• Entitlements and summons.
• The precepts editor.
• Earning rep.
• The client windows (next slice).

Verification

• cargo test -p game -p net -p runtime: all pass.
• Harness: families (new) 1/1, guilds 7/7, buddy_list 1/1.
• A Sonnet review (b043) found nine items; F1–F6 are fixed in the second commit.
