docs: update semantic commit guide to use feat(timeout)

Update SEMANTIC_COMMITS.md to use feat(timeout) instead of docs(timeout)
as requested. The timeout feature documentation exposes user-facing
functionality and warrants a feature-level semantic version bump.

Changed commit 323f26a recommendation from:
- docs(timeout): add comprehensive timeout configuration guide

To:
- feat(timeout): add configurable timeout support for FetchNode

Addresses feedback from @VinciGit00.

 This PR contains commits that need to be rewritten to follow Conventional Commits format for semantic-release compatibility.
 
+**Note:** The timeout documentation is marked as `feat(timeout)` (not `docs`) because it exposes a user-facing feature. Even though the implementation existed, this PR makes the feature discoverable and usable by users through documentation, which warrants a feature-level semantic version bump.
