Round N+1's fresh bot thread realloc'd module-level strings/seqs (SVG buffer, intent stdout/stderr, team messages) left behind by dead round N's thread — same rawDealloc SIGSEGV class as the event queue, seen at graphics.nim:274 (drawText->prepareAdd, core 2490478 @ 03:13:40, battle round 257). - graphics.nim: gSvgBuffer -> array[16384, char] + gSvgLen, appendSvg - bot.nim: intent stdout/stderr -> static char arrays; team messages -> array[16, TeamMessage] + len; buildIntentJson/printToStdOut/Err/ broadcastTeamMessage bounded appends - botThreadEntry: reset graphics+intent buffers on the owning thread Also fixes stale mapActions call sites in tests/ (missing enemyX/enemyY).
