Syncs libs/tankroyale_botapi with SirStone/robocode_tankroyale_botapi
v1.0.1 (extracted from tank-royale nim branch @ 03195a814). The local
SIGSEGV fixes (static event queue/SVG/intent buffers) were already
ported upstream in issue #24 — content is otherwise identical.
New capability (upstream #23): opponent name exposure for ticket #49.
- bot.nim: gBotNames id→name table + getBotName(id) / updateBotNames()
- umbrella module: dispatch BotListUpdate messages to updateBotNames()
Vendored layout and wiring unchanged (--path via config.nims, module
name stays tankroyale_botapi).
The event queue's heap seq was the last GC'd block surviving across
rounds: each round runs on a freshly spawned bot thread, so the N+1
thread realloc'd a block grown by dead thread N's allocator mid-round
(at the next capacity doubling, ~turn 104) -> rawDealloc SIGSEGV in
addEvent (7 gdb-confirmed coredumps). Replace with a static
array[MAX_QUEUE_SIZE, BotEvent] + eventsLen: no heap block crosses
threads, realloc can never happen.
Also fix the harness aborting the final round mid-train: PPO_Bot's
onRoundEnded trains synchronously after the runner's RoundEndedEvent,
so the counter read right after awaitResults() is the stale pre-train
value and System.exit killed the bot inside ppoUpdate. Poll up to 60s
for the counter to catch up before declaring the battle incomplete.
Verified: 72 consecutive rounds vs Fire, 100% wins, all rounds trained
(counter advanced 1:1), zero coredumps since the fix.
