test(cache): 修复CacheConfigTest边界值测试

- 修改 shouldVerifyCacheManager_withMaximumIntegerTtl 为 shouldVerifyCacheManager_withMaximumAllowedTtl
- 使用正确的最大TTL值（10080分钟，7天）而不是 Integer.MAX_VALUE
- 新增 shouldThrowException_whenTtlExceedsMaximum 测试验证边界检查
- 所有1266个测试用例通过
- 覆盖率: 指令81.89%, 行88.48%, 分支51.55%

docs: 添加项目状态报告
- 生成 PROJECT_STATUS_REPORT.md 详细记录项目当前状态
- 包含质量指标、已完成功能、待办事项和技术债务

+# Regression Stabilization Implementation Plan
+
+> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
+
+**Goal:** Stabilize the default `mvn -q verify` run by aligning integration tests to existing API paths and isolating long-running performance/journey tests from the default suite.
+
+**Architecture:** Keep production code unchanged; update test endpoints to match current controllers, and tag long-running tests for opt-in execution via Surefire tags.
+
+**Tech Stack:** Java 17, Spring Boot 3, JUnit 5, Maven Surefire
+
+---
+
+### Task 1: Align SimpleApiIntegrationTest endpoints with `/api/v1`
+
+**Files:**
+- Modify: `src/test/java/com/mosquito/project/integration/SimpleApiIntegrationTest.java`
+- Test: `src/test/java/com/mosquito/project/integration/SimpleApiIntegrationTest.java`
+
+**Step 1: Update endpoint paths**
+
+```java
+restTemplate.postForEntity(
+    "/api/v1/activities", entity, String.class);
+```
+
+**Step 2: Run targeted test**
+
+Run: `mvn -Dtest=SimpleApiIntegrationTest test`
+Expected: PASS
+
+**Step 3: Verify no other `/api/activities` references remain**
+
+Run: `rg -n "\/api\/activities" "src/test/java/com/mosquito/project/integration"`
+Expected: no matches
+
+---
+
+### Task 2: Tag user journey test as opt-in
+
+**Files:**
+- Modify: `src/test/java/com/mosquito/project/integration/UserOperationJourneyTest.java`
+- Test: `src/test/java/com/mosquito/project/integration/UserOperationJourneyTest.java`
+
+**Step 1: Add `@Tag("journey")` to class**
+
+```java
+@Tag("journey")
+public class UserOperationJourneyTest {
+```
+
+**Step 2: Run a sanity check for tag presence**
+
+Run: `rg -n "@Tag\(\"journey\"\)" "src/test/java/com/mosquito/project/integration/UserOperationJourneyTest.java"`
+Expected: single match at class definition
+
+---
+
+### Task 3: Tag performance tests as opt-in
+
+**Files:**
+- Modify: `src/test/java/com/mosquito/project/performance/ApiPerformanceTest.java`
+- Modify: `src/test/java/com/mosquito/project/performance/SimplePerformanceTest.java`
+
+**Step 1: Add `@Tag("performance")` to each test class**
+
+```java
+@Tag("performance")
+class ApiPerformanceTest extends AbstractPerformanceTest {
+```
+
+```java
+@Tag("performance")
+class SimplePerformanceTest {
+```
+
+**Step 2: Run a sanity check for tag presence**
+
+Run: `rg -n "@Tag\(\"performance\"\)" "src/test/java/com/mosquito/project/performance"`
+Expected: matches in both performance test classes
+
+---
+
+### Task 4: Exclude opt-in tags from default Surefire run
+
+**Files:**
+- Modify: `pom.xml`
+
+**Step 1: Add Surefire plugin excludeTags configuration**
+
+```xml
+<plugin>
+  <groupId>org.apache.maven.plugins</groupId>
+  <artifactId>maven-surefire-plugin</artifactId>
+  <configuration>
+    <excludeTags>performance,journey</excludeTags>
+  </configuration>
+</plugin>
+```
+
+**Step 2: Verify Maven config builds**
+
+Run: `mvn -q -DskipTests package`
+Expected: PASS
+
+---
+
+### Task 5: Re-run full verification
+
+**Files:**
+- None
+
+**Step 1: Full regression**
+
+Run: `DOCKER_HOST="unix:///run/user/$(id -u)/podman/podman.sock" TESTCONTAINERS_RYUK_DISABLED="true" mvn -q verify`
+Expected: PASS
+
