v2.4.0 — Apple Watch tactical-computer companion (watchlink)

Live Apple Watch tactical-computer support for the old-Mac yquake2 port.

New

• watchlink (src/client/cl_watchlink.c) — a cvar-gated UDP/JSON feed of the marine's live state: health, armor, ammo, current weapon, powerups, pickups, damage, the full carried inventory, and a silent mirror of the F1 help-computer objectives (location / kills / goals / secrets). An iPhone relays it over the LAN to an Apple Watch, turning the wrist into Quake II's in-fiction help computer with damage haptics and event sounds.
  • Off by default — gated on watch_host (empty ⇒ no socket, no per-frame work). Point it at a host or use Bonjour. Debuggable with nc -ul 27999 or scripts/watchlink-listen.py. Protocol + integration points in docs/WATCHLINK.md.
  • Companion app (iPhone relay + watchOS HUD): https://github.com/matthewdeaves/quake2-tactical-watch
  • Stays inert during timedemo benchmarks (zero fps impact); dedups repeated centerprints.

Verified

• DMG content-verified byte-for-byte vs source (Tiger-built, mounts Panther→modern).
• DMG-installed + smoke-tested on the G4 mini (Tiger, Radeon 9200): world rendered, 36.8 fps.

One fat image (ppc750 + ppc7400 + ppc970 + x86_64) installs on every supported Mac, G3 Panther through modern Intel.
