chore: align package entry metadata

[Egge21M]

What changed

• point published package entry fields at built dist artifacts instead of source index.ts files
• normalize module entries to dist/index.js where the build emits .js
• add missing main and types fields for packages that publish build output
• remove the stray module field from the private docs package

Why

Several package manifests were still advertising source files or outdated output filenames. That leaves the published metadata out of sync with the actual build artifacts and can break consumer resolution depending on the toolchain.

Impact

Consumers of the published packages get consistent main / module / types metadata that matches the generated files.

Validation

• bun run build
