P1 Badge Upload the function-local package manifest for API deploys

When a user adds a bare-specifier dependency to this generated manifest and runs the default supabase functions deploy, the API deployment path cannot resolve it: writeSourceDeployForm in apps/cli/src/shared/functions/deploy.ts only uploads the entrypoint and reachable local/import-map files, and its import walker skips bare specifiers, so this package.json is never included in the multipart upload. The deployed runtime therefore has neither the manifest nor the dependency declaration; either include the manifest in source uploads or route package-based functions through the bundler.
