chore(lint): vendor anti-slop oxlint plugin and add batched cleanup pipeline

Vendor the anti-slop Oxlint plugin at tools/oxlint/anti-slop and register it
in oxlint.config.ts, with Oxlint's own rule categories disabled so ESLint
stays the general-purpose linter.

Add scripts/anti-slop.mjs (bun run deslop) mirroring the React Doctor batch
interface: next-batch, check-batch, active, release, top, file. Batch handoff
directories now double as file claims shared across clones via
~/.openchamber/maintenance-claims, so concurrent maintenance batches from
either pipeline never select the same file.

Harden both scheduled maintenance flows: stop on a dirty worktree, stop on
NO BATCH AVAILABLE, validate per package instead of workspace-wide, and pin
react-doctor to 0.9.12. The anti-slop task command documents concrete
good and bad fixes and forbids laundering types to satisfy a rule.
