fix: v0.5.4 — defer process.exit until postSuggestions async chain resolves

[omrdev1]

Summary

Fixes a race condition where process.exit(policyExitCode) was called synchronously at the bottom of cli.ts before the async postSuggestions HTTP chain to the GitHub API had resolved.

Impact: On any build with --post-suggestions enabled and a policy violation (fail_on_violation: true), the process would exit code 1 before suggestion comments were posted to the PR. The build would fail with no inline remediation visible to the developer.

Fix: process.exit is now deferred into the .finally() block of the postSuggestions Promise chain, ensuring the GitHub API calls complete before the process terminates — regardless of whether suggestions succeeded, failed, or timed out.

Checklist

• npm test passes (86/86)
• npx tsc --noEmit passes (zero type errors)
• npm run build produces clean dist
• No behaviour change when --post-suggestions is not used

• Current: n2-standard-2 in us-central1
• Suggested: n2-standard-2 in europe-north1
• Scope 2 Impact: -3.52kg CO2e/month | +$8.03/month
• Rationale: Moving n2-standard-2 from us-central1 to Finland (europe-north1) reduces grid carbon intensity from 340g to 18g CO2e/kWh, saving 3516g CO2e/month (note: cost increases by $8.03/month). Water consumption also decreases by 2.8L/month.
