feat: add GitHub and GitLab webhook support

Add auto-detection of webhook source (Gitea, GitHub, GitLab) by
examining HTTP headers (X-Gitea-Event, X-GitHub-Event, X-Gitlab-Event).

Parse push webhook payloads from all three platforms into a normalized
PushEvent type for unified processing. Each platform's payload format
is handled by dedicated parser functions with correct field mapping
and commit URL extraction.

The webhook handler now detects the source automatically — existing
Gitea webhooks continue to work unchanged, while GitHub and GitLab
webhooks are parsed with their respective payload formats.

Includes comprehensive tests for source detection, event type
extraction, payload parsing for all three platforms, commit URL
fallback logic, and integration tests via HandleWebhook.
