Deferred, not rejected — and now blocked for a measured reason rather than an unverified one. Building this revealed: node>=25 removed corepack, and better-sqlite3 has no prebuild for that ABI so pnpm falls back to node-gyp, which needs a Python toolchain the slim builder lacks. python:3.14 fails the same way: asyncpg and tree-sitter publish no wheels, so pip builds from source with no gcc. Both blockers are now recorded in the Dockerfile with their exact errors. Reopen once upstream ships binaries, or land a separate change adding the toolchain.

OK, I won't notify you again about this release, but will get in touch when a new version is available. If you'd rather skip all updates until the next major or minor version, let me know by commenting @dependabot ignore this major version or @dependabot ignore this minor version. You can also ignore all major, minor, or patch releases for a dependency by adding an ignore condition with the desired update_types to your config file.

If you change your mind, just re-open this PR and I'll resolve any conflicts on it.
