refactor: break up _build_gitea_tools() into per-operation helpers

Extract each Gitea tool builder into its own top-level function:
- _build_list_issues_tool(base_url, token, owner, repo)
- _build_create_issue_tool(base_url, token, owner, repo)
- _build_read_issue_tool(base_url, token, owner, repo)

_build_gitea_tools() is now 12 lines (was 137) — just assembles the
three helpers with shared connection params.

Fixes #1134
