A Cloudflare Workers app with stricter settings than ours (noUncheckedIndexedAccess, exactOptionalPropertyTypes, Workers types instead of Node's) couldn't typecheck once it imported pi-optchat/core or pi-optchat/durable. Both pointed at our raw .ts source, so the app's compiler checked our files under the app's own settings; skipLibCheck only skips .d.ts. Such an app got dozens of errors in our code (66 in the test app below). Plain Node couldn't load them either, since it won't strip types from files in node_modules.

Fix

The package now ships core and durable built: tsconfig.build.json emits .js and .d.ts to dist/ (rewriteRelativeImportExtensions turns our .ts imports into .js), and prepack runs npm run build, so npm pack and the Publish workflow's npm publish always include it. Source stays in src/, and our own tsconfig is unchanged: no stricter flags, no guard edits.

. and pi.extensions stay on ./src/index.ts: Pi loads and compiles its extensions itself, so that path works today and is left alone.

Entry points changed

• pi-optchat/core: now dist/core/index.js with types dist/core/index.d.ts (was src/core/index.ts).
• pi-optchat/durable: now dist/durable/index.js with types dist/durable/index.d.ts (was src/durable/index.ts).
• pi-optchat (the Pi extension): unchanged.

Test

test/consumer-workers is a tiny Workers app (strict, noUncheckedIndexedAccess, exactOptionalPropertyTypes, skipLibCheck, only @cloudflare/workers-types) that opens a memory on SqliteStore and builds optchat() and optchatImport(). CI installs it from the tarball npm pack produces, typechecks it, and imports both entry points in plain Node, so a missing dist/ in files fails too. The branch's first commit adds only this check, and it failed against the old exports.

examples/durable-object still links the repo with file:../.., so run npm run build first (noted in docs/durable.md); its tsc and wrangler deploy --dry-run pass.

What changed in this PR

This PR ships built JavaScript and declarations for pi-optchat/core and pi-optchat/durable, supporting stricter TypeScript consumers and plain Node imports while leaving the Pi extension entry point unchanged.

Changes:

• Adds a build and prepack step, redirects subpath exports to dist/, and includes build output in the package.
• Adds a strict Workers consumer fixture and CI checks against the packed package.
• Documents the build prerequisite for the linked Durable Object example.
