fix(ci): pin third-party actions to full commit SHAs

The account's Actions policy requires a full-length SHA ref. A tag or branch ref is refused at
startup — startup_failure, no jobs, "this workflow graph cannot be shown" — so these workflows
could not run at all. This resolves each ref to the commit it currently points at and records the
ref in a trailing comment, e.g. actions/checkout@<sha> # v4.

dtolnay/rust-toolchain takes its toolchain from the ref itself, so those steps also gained an
explicit with: toolchain: input; without it, a SHA ref would silently lose the channel.

No behaviour is intended to change beyond the pins.

📝 Summary

Summary by CodeRabbit

  • Chores
    • Pinned GitHub Actions used by build, deployment, security scanning, notification, and synchronisation workflows to immutable commit references.
    • Preserved version annotations for easier maintenance and auditing.
    • Workflow behaviour and triggers remain unchanged.

Walkthrough

GitHub Actions references across eight workflows now use immutable commit SHAs instead of mutable tags. Version comments remain where supplied. Workflow triggers, job logic, permissions, and notification content are unchanged.

Runtime workflow behavior should remain intact, but two small dependency-traceability inconsistencies should be corrected or explicitly accepted.

A rabbit pins actions tight,
No drifting tags can hop from sight.
Each workflow keeps its steady track,
With version notes beside each SHA.
The builds now follow footprints true,
And dispatch paths stay fixed too.

Include the original v0.3.0 ref in the trailing comment.

The SHA matches .github/workflows/actions.lock, but the comment only identifies the lockfile authority. Add # v0.3.0 while retaining the NOSONAR note so the pin remains traceable to the intended release.

Regenerate the generated action lockfile.

trufflesecurity/trufflehog@288a8a8643a2c5a36b81d231c550dccfa0beeb64 is the current main commit. .github/workflows/actions.lock still records the previous main commit, so regenerate it with gh actions-lock to update the dependency inventory.
