Method PruneStaleGHAWEntries

pkg/workflow/action_cache.go:691–719

PruneStaleGHAWEntries removes entries from the cache for the gh-aw-actions repository whose version does not match the current compiler version. When the compiler is updated (e.g., from v0.67.1 to v0.67.3), previously compiled workflows referenced setup@v0.67.1 but the new compiler pins to setup@v0

(currentVersion string, actionsRepoPrefix string)

//   - currentVersion: the compiler version that is currently in use (e.g., "v0.67.3")
//   - actionsRepoPrefix: the org/repo prefix for gh-aw-actions (e.g., "github/gh-aw-actions")
func (c *ActionCache) PruneStaleGHAWEntries(currentVersion string, actionsRepoPrefix string) {
	if currentVersion == "" || actionsRepoPrefix == "" {
