collab/mcp: bundle workspace deps so runtime doesn't import .ts files

@tasks/database (and @tasks/shared) export raw .ts files via "main" /
"exports", which works fine for tsx/dev but blows up at runtime in the
production image:

  ERR_UNKNOWN_FILE_EXTENSION: Unknown file extension ".ts" for
  /app/packages/database/src/client.ts

tsup was leaving those workspace imports as externals in the output, so
the deployed dist/index.mjs still tried to resolve them at startup.
Switch each app to a tsup.config.ts that sets noExternal: [/^@tasks\\//],
which inlines workspace packages into the bundle while keeping
node_modules deps (postgres, drizzle-orm, hocuspocus, mcp-sdk, etc.)
external.

Verified locally: collab-server bundle size goes from 7 KB to 304 KB,
confirming @tasks/database is now compiled in. Also fixed the collab
start script to point at index.mjs (tsup ESM output) instead of .js.
