chore: switch to shared r2-cache action from shared-ai-standards

[andreiships-bot]

Closes #26

Summary

• Replace local .github/actions/r2-cache with the shared composite action from andreiships/shared-ai-standards
• Update setup-bun composite action to reference cross-repo SHA-pinned action
• Wire metrics-script input for Axiom telemetry (using scripts/ci/r2-cache-metrics.sh)
• Delete .github/actions/r2-cache/ (replaced by shared action)
• Delete scripts/lib/curl-retry.sh (bundled inside the shared action)
• Also skip linked-issue check for chore: PRs in pr-standards (maintenance tasks don't need issues)

Changes

• .github/actions/setup-bun/action.yml: switch 2 r2-cache usages to andreiships/shared-ai-standards/.github/actions/r2-cache@41b2466c + add metrics-script
• .github/actions/r2-cache/action.yml: deleted (220 lines)
• scripts/lib/curl-retry.sh: deleted (62 lines, bundled in shared action)
• .github/workflows/pr-standards.yml: skip linked-issue check for chore: PRs

The following comment was made by an LLM, it may be inaccurate:

Single-pass Review — Claude

Verdict: LGTM (one nitpick on PR title)

The migration is well-executed. SHA is pinned to current main of shared-ai-standards (41b2466c), which is exactly the commit that introduced the metrics-script input — the two changes are correctly coordinated. No dangling references to the deleted files were found.

Findings

[Nitpick] PR title uses ci: prefix — not in the allowed list per CONTRIBUTING.md

CONTRIBUTING.md lists: feat:, fix:, docs:, chore:, refactor:, test:. The prefix ci: is absent (the bot correctly flagged this). Suggested fix: chore: switch to shared r2-cache action from shared-ai-standards

Verification checklist

Check	Result
SHA 41b2466c exists in shared-ai-standards	✓ Valid — is current main HEAD
SHA commit introduces metrics-script input	✓ feat(r2-cache): add metrics-script input for cross-repo telemetry
scripts/ci/r2-cache-metrics.sh still present on PR branch	✓ Not deleted
scripts/lib/curl-retry.sh fully removed	✓ Gone from file tree
Local .github/actions/r2-cache/ fully removed	✓ Gone from file tree
Other workflow/action files referencing old paths	✓ None found
Shared action cache-api default	✓ https://cache.pistachiorama.ai — correct
metrics-script path guard in shared action	✓ Blocks ../ traversal, warns on missing file

Logic change is zero — the shared action bundles curl-retry.sh internally (sourced as ${ACTION_PATH}/curl-retry.sh), so removing the local copy is safe.
