Drop classic loldle from 8 → 6 (7-axis grid leaks too much per guess for 8
to feel earned) and emoji from 5 → 4 (3 emojis are usually unmistakable).
Add a hidden /<module>_setmax <n> command per loldle module so a chat can
override its own round length (1-10). Override stored at config:<subject>
in each module's KV; getMaxGuesses() falls back to the default when unset.
Three feature plans (semantle, twentyq, loldle-new-modes) are
status:completed in their frontmatter and the corresponding modules
exist in src/modules/. Move them to plans/archive/ to keep the active
plans/ dir focused on in-flight work.
Atlas migration (260425-1945-mongodb-atlas-migration/plan.md): bump
status from `planning` to `code-complete` and annotate each phase row
with its commit SHA + whether operator action is still pending. Plan
stays in active plans/ until cutover lands or the Upstash standby
(phase-07-alt-pivot.md) executes.
No code changes. Tests, lint, register:dry unaffected (733 passing).
Operator-facing summary in the plan.md status note: 8 phases of
implementation are committed on dev (6f0b5ff..e2e3112). Outstanding
operator work: Atlas provisioning, real-cluster smoke tests,
backfill runs, soak, cutover stages, Stage 3 code cleanup.
