fix publish scope rewrite for dist output

[qingliaowu]

Summary

This fixes #35

Fixes the release-time scope rewrite so published packages do not keep @agentscript/* imports in their compiled dist files.

The publish script already rewrites package metadata from @agentscript/* to @sf-agentscript/*, but the compiled JS and type declaration files are produced before that rewrite happens. As a result, the published package can install dependencies under @sf-agentscript/* while the runtime code still imports @agentscript/*.

This PR extends the publish step to also rewrite built output files before publishing.

What Changed

• Rewrites @agentscript/* to @sf-agentscript/* inside package dist folders
• Covers JS, CJS, MJS, declaration files, and source maps
• Keeps the internal source code unchanged
• Adds a patch Changeset so affected public packages are republished with corrected output

Why This Fix

This keeps the existing development workflow intact while making the npm-published artifacts match the published package scope.

That means installed packages should resolve imports like:

@sf-agentscript/parser






## What

Fixes release-time scope rewriting so published packages do not keep `@agentscript/*` imports in compiled `dist` files.

## Why

The publish script already rewrites package metadata from `@agentscript/*` to `@sf-agentscript/*`, but compiled output is built before that rewrite. This means npm installs dependencies under `@sf-agentscript/*` while runtime JS can still import `@agentscript/*`, causing module resolution failures.

Fixes #35.

## How

Extended `scripts/publish.mjs` to rewrite built package outputs under each package’s `dist` directory before publishing.

The rewrite covers publish artifacts where package specifiers can appear:

- `.js`
- `.mjs`
- `.cjs`
- `.d.ts`
- `.d.mts`
- `.d.cts`
- `.map`

The source packages still use the internal `@agentscript/*` scope during development; only publish-time artifacts are rewritten.

Added a patch Changeset so affected public packages are republished with corrected `dist` output.

## Test Plan

- [x] Existing tests pass (`pnpm test`)
- [x] New/updated tests cover the change
- [x] Linting and type checks pass (`pnpm lint && pnpm typecheck`)
- [x] `node --check scripts/publish.mjs`
- [x] Smoke-tested `rewriteDistFiles` against nested `.js`, `.d.ts`, and `.map` files
- [x] `pnpm dlx prettier@3.8.1 --check scripts/publish.mjs .changeset/fix-publish-dist-scope.md`
