fix: resolve test coverage regression and locked PR comment failure

[Copilot]

The "Test Coverage" CI job was failing for two independent reasons: a branch coverage regression introduced by the new --openai-api-target/--anthropic-api-target flags, and an unhandled 403 when trying to comment on a locked PR.

Coverage regression fix

The new validation warning logic was inlined inside program.action() — which is never exercised by unit tests — adding ~10 untested branches and dropping overall branch coverage from 74.82% → 74.03%.

Extract into testable function (src/cli.ts):

export function emitApiProxyTargetWarnings(
  config: { enableApiProxy?: boolean; openaiApiTarget?: string; anthropicApiTarget?: string },
  allowedDomains: string[],
  warn: (msg: string) => void
): void { ... }

Call site uses logger.warn.bind(logger) (no new anonymous function added to the count):

emitApiProxyTargetWarnings(config, allowedDomains, logger.warn.bind(logger));

• Added 7 unit tests for emitApiProxyTargetWarnings covering all branch paths
• Added 4 unit tests for OPENAI_API_TARGET/ANTHROPIC_API_TARGET env var forwarding in generateDockerCompose
• Net result: branch coverage 75.2%, functions 83.01% — both above base (74.82% / 82.77%)

Locked PR comment fix

Added continue-on-error: true to the "Comment PR with coverage comparison" step in test-coverage.yml. Coverage data is still available via job summary and uploaded artifact.
