[bishopBethel]

Return full bounty details including creator info (username, avatar), application count, assignee info if assigned, and current status.

I can take this and ship a minimal, review-ready endpoint quickly.

Proposed deliverable (within 12h):

• GET /bounties/:id with full bounty detail payload
• includes creator (username, avatar), application count, assignee info, status
• clear 404/validation handling and response typing
• one focused test path for success + one for not found

If this scope works, please assign me and I’ll open the PR with verification steps in the description.
