refactor: split http/mcp/diagnostics.rs (861) into mod + permission + usage
The 861-line diagnostics.rs is split: - permission.rs: tool_prompt_permission + helpers + their tests (584 lines) - usage.rs: tool_get_token_usage + tests (122 lines) - mod.rs: server_logs, rebuild, version, loc_file, dump_crdt, move_story + tests (185 lines) Tests stay co-located. The bigger sub-modules (permission at 584 with tests mostly under 800; usage at 122) are well within the 800-line guide. Also added #[allow(unused_imports)] to two now-pedantic re-exports in service/diagnostics/mod.rs that the split made flag. All 2636 tests pass; clippy clean.
