Rebases the vendored engine, content and webclient onto upstream's 289
branches (34 engine, 165 content, 9 webclient commits past our 274 base).
Each vendor-289 branch in ../repos is upstream 289 plus one squashed
"rs-sdk local mods" commit, refreshed from this tree first.
289 adaptations:
- Protocol: 289 reshuffles every opcode. Custom MESSAGE_PUBLIC (server 255)
and MARKET_SEARCH (client 243) are still free and kept.
- Lite client: CLIENT_VERSION 289, UPDATE_INV_FULL size g1->g2 and
UPDATE_INV_PARTIAL slot g1->gsmart, mirroring Client.ts.
- Content ids: upstream appended configs where ours lived. GE interface
moves 10984->11942 (through 12437), grand_exchange_booth 4671->5116,
grand_exchange_teller 1359->1596 (m49_53.jm2 updated), pvp_death_mark
varp 358->394. PlayerLoading moves a saved varp 358 value to
pvp_death_mark (289's varp 358 is temp-scoped, so only pre-289 saves
carry it).
- GE loc/npc configs use 289's renamed model debugnames.
- Engine: keep our Bun web split over upstream's new Fastify web.ts (no
fastify/tsx deps), add OnDemand.onClientClosed to our WS close handler,
keep our WSClientSocket API/batching and the 1s delayed close (TCP too).
Adopt upstream's HashTable iterator fix, IPv6 player-loop key (with our
NaN guard), chat effects 0-5, pointer-check removal.
- Razmire building store keeps our 650 sell price with upstream's 4% haggle.
- Tests: opcode assertions use ClientProt enums; hand-built inv packets
use the 289 layout.
PATCHES.md documents the new per-upgrade steps (custom id renumbering,
lite decoder parity, opcode collision check).
