The wsapi server was built on the signal context, so SIGTERM cancelled
every room before StartDraining ran and the restart notice never went
out. Build it on a background context, release the signal context as
soon as it fires, and wait a bounded moment after Shutdown so the notice
reaches open sockets.
Also: Hard prefers the slower loss in lost positions; resigning out of
turn no longer settles a pending dead end on the spot; a self-closing
<ref> with a slash in its name no longer swallows definition text; the
store enforces builder_version; both listeners get an IdleTimeout; the
real-corpus ladder is reproducible from its seed; a -healthcheck flag
probes /healthz for the container health check.
bot.BoardFor and hub.roomCount were reachable from tests only and now live beside them; session.serve drops an always-true nil check (readLoop never returns nil); invisible characters in test literals become escapes; comments no longer cite plan phases; `.dockerignore` keeps the dump out of the build context. No behaviour change; vet, deadcode, staticcheck, go test -race, svelte-check and vitest green.
reader for both wikitext dialects; `meanings(word, ord, pos, gloss)` table; `meaning_count`/`words_with_meaning`/`source_pages` in meta, `source_rows` gone, builder_version 5; `--dump`/`--min-pages` replace `--kaikki`; attribution names the dump and the definition excerpts; 36,200 words, 96.9% with a meaning, every kaikki word kept.
