chore(ci): pin actions to immutable commit SHAs

[yordis]

• Mutable tags let an upstream maintainer change what runs here after the fact, and pinning is a prerequisite for turning on the organization SHA pinning policy without taking CI down.

PR Summary

Low Risk
CI-only supply-chain hardening with no application or runtime logic changes; same action versions, referenced immutably.

Overview
Pins third-party GitHub Actions to full commit SHAs instead of mutable version tags, with inline comments noting the original tag (e.g. v5.0.0).

In CI (ci.yml), actions/checkout, actions/setup-go, and golangci/golangci-lint-action are pinned. In Release Please (release-please.yml), googleapis/release-please-action is pinned the same way. Workflow steps and behavior are unchanged; only how each action is referenced is updated so runs use fixed upstream revisions and org SHA-pinning policies can be enforced without breaking pipelines.

Walkthrough

The CI and Release Please workflows now reference GitHub Actions by immutable commit SHA values. Existing workflow steps, version comments, and Go matrix configuration remain unchanged.

Changes

GitHub Action Pinning

Layer / File(s)	Summary
Pin workflow action references .github/workflows/ci.yml, .github/workflows/release-please.yml	The CI and Release Please workflows replace mutable action tags with commit SHA references. Existing workflow configuration remains unchanged.

Estimated code review effort: 1 (Trivial) | ~5 minutes

Merge Risk: 🔵 Low · up to c124b

This PR pins CI and release actions to immutable commits, reducing the chance of unreviewed upstream changes, but two pinned actions still depend on Node 20 and must be updated before September 23, 2026; the change is mergeable with explicit owner follow-up.

Poem

A rabbit checks each workflow line
And finds the actions fixed in time
The tags now rest on hashes true
CI hops through what commits do
Release follows the same trail

Replace both Node 20-based action pins before September 23, 2026.

Both pinned actions use Node 20. Update actions/setup-go to v6.2.0 (7a3fe6cf4cb3a834922a1244abfce67bcef6a0c5) or later. Update googleapis/release-please-action to v5.0.0 or later. Pin both actions to full commit SHAs.
