The client side of families, on top of the server slice (#699).

Family window (UIWindow.img/Family, report b042)

• Opened with F (new default binding, HC action FAMILY 27 = v83's 26), from your own Char Info, and with BtFamily. Opening it sends OPEN_FAMILY.
• Shows the family name, the precepts marquee, juniors, Rep and today's Rep, and the entitlements one at a time with their tooltips.
• Its buttons are Add Junior, Pedigree, the precepts prompt (leader only, sends CHANGE_FAMILY_MESSAGE) and Use This (USE_FAMILY).

Family Tree (b044)

• Four generations around the character viewed, with who is online and the junior counts.
• On your own tree, the senior's and juniors' boxes light up, an empty junior box asks for a name, and each member has a tooltip (Rep, time online, location, entitlements used).
• Texts are centred the way v83 does it (0x808212 halves the leftover room as unsigned), so a text wider than its box is never drawn. In particular, "(You do not have family members.)" stays blank in empty boxes.
• BtBye stays disabled until separation exists.

Asked to join

• FAMILY_JOIN_REQUEST shows one invitation card, even when asked repeatedly.
• O on the card gives v83's Yes/No; X or the card fading out declines.
• It is auto-declined when the family-invite option is off.
• The results, join and Rep-gain chat lines, the OK dialogs for refusals, and relatives' login notices are handled (recv 94-102).

Also

• Char Info's Family button opens the window for yourself and someone else's tree for others.
• The context menu's Add Junior sends ADD_FAMILY.
• Esc closes either window when it is the topmost one (b045).
• Server: the default keymap gains F → Family (the unit test now counts 40); the tree's chart repeats the leader as the viewed one.

Verification

• build-dbg ctest: 152/152, including the new family parser/arrangement tests.
• Unit tests: game lib 134 and net lib 853, all pass.
• Harness: families and keymap_persistence pass.
• GUI check against the lane stack with a scripted senior:
  • the card, Yes/No and joining;
  • the window with long precepts scrolling on one line;
  • the tree with tooltips (self, senior, total);
  • Esc closing tree then window.
• Reviewed by a Sonnet agent (b046). Fixed from the review: the tree title's centring, the precepts wrapping, Esc on the window, and the empty-box text.
