fix: register retry + resetRegistration + isOwnedByAgent fail-closed (#448)
修復 PR #522 的 3 個問題： 1. Bug 1: register() 失敗後同一 API instance 可重試 - _registeredApis 從 WeakSet 改為 Map - try-catch 包住初始化，.set(api, true) 在成功後才執行 - catch block 不呼叫 .set()，允許失敗後重試 2. Bug 2: resetRegistration() 真正清除狀態 - WeakSet 無法 clear，改用 Map 後可呼叫 .clear() - 新增 _getRegisteredApisForTest() 供測試用 3. Bug 3: isOwnedByAgent malformed itemKind fail-closed - type=memory-reflection-item 時，只有 invariant/derived 合法 - 非法的 itemKind（如 weird-kind、空字串、數字等）→ return false - 修復 main derived 會洩漏給 sub-agent 的問題 新增測試： - test/isOwnedByAgent.test.mjs (19 tests) - test/register-reset.test.mjs (17 tests)
