Prepare Dibs 0.2.0-rc.0

[fasterthanlime]

Summary

Prepare Dibs for the Facet 0.50 prerelease train by moving the workspace to the published rc crates and bumping the publishable Dibs crates to 0.2.0-rc.0 (facet-tokio-postgres to 0.50.0-rc.0).

This also includes the existing CI cleanup commits from local main: actionlint configuration and Node 24 action runtime updates.

Changes

• Update Facet, Figue, Styx, Strid, Vox, Phon/Moire-transitive lockfile dependencies to the prerelease stack.
• Bump publishable Dibs workspace crate versions and internal dependency requirements.
• Migrate Dibs Vox session setup to Vox 0.9 (initiator_on(link), no TransportMode, no non_resumable()).
• Match boxed VoxError::User(Box<DibsError>) in the migration error rendering path.
• Add actionlint config and update workflow action runtimes.

Testing

• cargo check --workspace --all-targets
• cargo fmt --all -- --check
• cargo clippy --all-features --all-targets --message-format=short -- -D warnings
• actionlint
• cargo nextest run --workspace --all-features --no-tests=pass -E 'not (binary(postgres_integration) | binary(integration) | binary(query_integration))' — 202 passed, 1 skipped
• cargo package --allow-dirty -p dibs-jsonb -p dibs-sql -p dibs-db-schema -p dibs-macros -p dibs-proto -p dibs-query-schema -p dibs-qgen -p dibs -p dibs-config -p dibs-cli -p facet-tokio-postgres -p dibs-runtime

Full local nextest and the pre-push hook both reached the Docker-backed Postgres integration tests and failed because this machine has no Docker daemon socket at /Users/amos/.docker/run/docker.sock; CI should exercise those with its service/container setup.
