chore: version packages

[github-actions]

This PR was opened by the Changesets release GitHub action. When you're ready to do a release, you can merge this and the packages will be published to npm automatically. If you're not ready to do a release yet, that's fine, whenever you add more changesets to main, this PR will be updated.

Minor Changes

• 35d9f3e: Scaffold new projects on PostgreSQL 18, and run the conformance harness on it too.

  seamless init generated a stack pinned to postgres:17 while the verify harness ran postgres:16.
  Both are now postgres:18, so what the harness certifies is the major a fresh scaffold actually
  gets.

  This does not touch an existing project. The image is written into each scaffold's own
  docker-compose.yml at generation time, so a project keeps whatever major it was scaffolded with and
  its data directory is never pulled out from under it. Only newly scaffolded projects get 18, on a
  fresh volume. Upgrading an existing project is a deliberate act: change the image in its
  docker-compose.yml, and dump and restore the volume, since PostgreSQL will not start against a data
  directory written by a different major.

• d5da781: seamless verify now exercises the Fastify starter. The scaffold has offered a Fastify API since the
  templates bump, but the conformance harness only ever drove the Express adapter, so a green run said
  nothing about whether a Fastify-scaffolded project actually worked.

  The stack gains a second adopter backend (verify/adapter-fastify-app, on port 3001) built on
  @seamless-auth/fastify, a twin of the Express one: same routes, same env contract, same capture
  transport. The existing adapter specs run against both without being duplicated, since the two
  Playwright projects share a test directory and differ only in which backend they point at. The
  conformance grid gains an adapter-fastify column, so a failure in one framework is attributable to
  that framework.

  --api-only and --no-react are unchanged, and --local builds and packs @seamless-auth/fastify
  from source alongside core and express.

Patch Changes

• 5cb6911: Fix the scaffolded database failing to start on PostgreSQL 18.

  The PostgreSQL 18 bump moved the image tag but not the volume mount. PostgreSQL 18+ images store data
  in a major-versioned subdirectory (/var/lib/postgresql/18/docker), so a mount at
  /var/lib/postgresql/data is ignored and the container refuses to start, restart-looping on:

  Error: in 18+, these Docker images are configured to store database data in a
         format which is compatible with "pg_ctlcluster" ...
         Counter to that, there appears to be PostgreSQL data in:
           /var/lib/postgresql/data (unused mount/volume)
  

  The generated docker-compose.yml now mounts pgdata:/var/lib/postgresql. See
  Change PGDATA in 18+ to /var/lib/postgresql/MAJOR/docker docker-library/postgres#1259.

  This only ever affected projects scaffolded from the unreleased PostgreSQL 18 change, so no published
  version of the CLI produced a broken scaffold.
