chore: purge legacy vocabulary (townhouse / town / dvm)

[toon-backlog-bot]

Closes #21

Summary

• tsconfig.json: removed dead exclude entries for entrypoint-town.ts and entrypoint-townhouse-api.ts (files that no longer exist)
• esbuild.config.mjs: removed dead '@toon-protocol/town' entry from the externals list (removed legacy package)
• entrypoint-store.ts: stripped @toon-protocol/townhouse / packages/townhouse from the bytes-formatter inlining comment; removed now-unnecessary @ts-expect-error for @ardrive/turbo-sdk types (types are now resolvable, directive triggered TS2578)
• entrypoint-store.test.ts: removed dead vi.mock('@toon-protocol/pet-dvm', ...) block for the removed kind:5250 Dungeon handler

All surviving dvm/DVM references (e.g. createArweaveDvmHandler, DvmHealthResponse, ArweaveDvmConfig, kind:5094 comments) are legitimate NIP-90 Data Vending Machine terminology and are left unchanged per the issue's CRITICAL EXCEPTION.

No wire identifiers, node-type strings, ILP addresses, or BTP transport fields were changed.

Verification

node esbuild.config.mjs   # build — ✅ succeeded
npx tsc --noEmit          # typecheck — ✅ clean
npx vitest run            # tests — ✅ 22/22 passed

Deviation from Agent Assessment

The issue body did not include a ## Agent Assessment heading but provided an equivalent mapping table and checklist; proceeded per the spirit of the precondition. One additional fix applied: removed a now-stale @ts-expect-error directive on line 158 of entrypoint-store.ts that was unrelated to the vocabulary rename but caused typecheck to fail (TS2578 — unused directive; the @ardrive/turbo-sdk types are now resolvable).

[ALLiDoizCode]

Reviewed all four changed files. No CODE issues found.

Checked:

• esbuild.config.mjs: @toon-protocol/town correctly dropped from externals; no package.json dependency and no source import remains.
• entrypoint-store.test.ts: dead vi.mock('@toon-protocol/pet-dvm', ...) removed; pet-dvm survives only in a comment listing example heavy-dep names, which is harmless.
• entrypoint-store.ts: comment trimmed correctly; @ts-expect-error removal is safe because the PR reports tsc --noEmit clean (TS2578 unused-directive confirms the types are now resolvable).
• tsconfig.json: the two dead exclude entries for non-existent files removed correctly; remaining dead entries (entrypoint-sdk.ts, entrypoint-toon-client.ts, entrypoint-toon-client-helpers.ts) are pre-existing and harmless.

METADATA fix applied: title claimed "mill" purge but no diff changes touch anything mill-related. Corrected title to chore: purge legacy vocabulary (townhouse / town / dvm).

CI build failing — TS2307 typecheck error

The build CI job is failing on the pnpm typecheck step:

src/entrypoint-store.ts(158,36): error TS2307: Cannot find module '@ardrive/turbo-sdk/node' or its corresponding type declarations.

Root cause: this PR removed the @ts-expect-error directive on entrypoint-store.ts:158 on the assumption that @ardrive/turbo-sdk/node types were now resolvable (the old directive suppressed TS2307; without it TS2578 appeared). But the types are still not resolvable — removing the directive re-exposes TS2307.

Fix needed: restore the @ts-expect-error comment on the line immediately before the dynamic import('@ardrive/turbo-sdk/node') in src/entrypoint-store.ts. A one-line fixup commit should clear the typecheck and turn CI green.

Everything else in the PR (tsconfig exclude cleanup, esbuild externals, dead test mock removal) is correct and approved.
