fix(inspection): bound AGT scanner calls with timeout; add scanner attribution (INJECT-002, INJECT-003) - #229

…tribution to result
INJECT-002: wraps scan_response() and PromptInjectionDetector.detect() in
ThreadPoolExecutor with a configurable timeout (default 5s). A timeout is
treated as deny (fail-safe) so a slow/unresponsive AGT service cannot
exhaust worker slots indefinitely.
INJECT-003: adds injection_scanner and injection_score fields to
InspectionResult and StageResult. Callers writing audit chain entries now
have the specific scanner that triggered the deny ("agt_mcp", "agt_detector",
"regex", "timeout", "utf8_guard") and confidence score if available.
