Test robustness / flake fix.

Why
should handle onReleaseChangelog hook errors gracefully was leaking the expected hook failure to stderr:

stderr | test/builder-changelog.test.ts > ... > should handle onReleaseChangelog hook errors gracefully
✘ [error] onReleaseChangelog error: Hook failed

DoculaConsole.error() always writes to console.error (even in quiet mode), so Vitest reports it as a failed-looking ✘ [error] line. The test also depended on the GitHub HTTP mock actually supplying releases, so the hook was not guaranteed to run.

What
Harden that test in test/builder-changelog.test.ts:

• Inject GitHub releases via getGithubData so the hook always runs
• Stub builder.console.error so the expected log does not leak to stderr
• Assert the error is logged and the changelog page is still built
