release: workflow runner v0.4.55

[Shooksie]

Summary

• bumps the workflow runner package and lockfile to v0.4.55
• releases the merged TASK-1071 fail-closed node-side publication and proof-verification fix

Verification

• cargo test --all-targets: 304 passed, 5 documented ignores
• cargo clippy --all-targets -- -D warnings
• cargo fmt --all -- --check
• git diff --check

After merge, tag the exact main commit as v0.4.55, wait for all three release binaries, then update the LaunchApp Portal runtime pin.

VERDICT: APPROVE

No blocking findings. GitHub reports no configured check runs or commit statuses for this head, so there is no CI signal to wait for. The release change is minimal and internally consistent: Cargo.toml and the root package entry in Cargo.lock both move from 0.4.54 to 0.4.55, with no unrelated source or dependency changes.

What is good: the PR is tightly scoped to release metadata, keeps the manifest and lockfile synchronized, and clearly documents the intended post-merge tag/release procedure.
