Add Entalpa to Community Friends - #4993

Description

Adds Entalpa to the Community Friends page (docs/community/friends.md). One entry, nothing else touched.

Entalpa reads a public Spec Kit repository's specs/<feature>/spec.md and tasks.md and folds the features into one current backlog: user stories, FR-/SC- requirements linked to them with statuses from tasks.md, and clarifications as answered questions. A later feature revises the story it changes instead of adding a copy, and the result can be exported back as a specs/ feature.

The entry discloses the account boundary (viewing needs no account, keeping or editing does) and that the specs go to third-party AI providers, which is why only public repositories are accepted.

Docs only: no code and no catalog change, so no submission issue.

Testing

Markdown only. Checked the rendered page in my fork and that https://entalpa.com/spec-kit resolves and lets you paste a repository without signing up.
