feat(k8s): implement clean-room Kubernetes management GUI

- Backend: kube module with ClusterClient, PortForwardSession, RefreshRegistry
- 7 Tauri IPC commands: add_cluster, remove_cluster, list_clusters, start_port_forward, stop_port_forward, list_port_forwards, delete_port_forward, shutdown_port_forwards
- AppState extended with clusters, port_forwards, refresh_registry fields
- Version bumped to 1.1.0 in Cargo.toml and package.json
- Auto-tag workflow updated to mark releases as draft (pre-release)
- Buy Me A Coffee section added to README.md
- Fixed changelog workflow to only include current tag commits
- Proper kubeconfig YAML parsing with extract_context and extract_server_url
- Added kubeconfig content storage in ClusterClient
- Updated PortForwardSession to include cluster_name
- Frontend GUI components: ClusterList, PortForwardList, AddClusterModal, PortForwardForm, KubernetesPage
- TypeScript types and IPC commands for Kubernetes management
- Unit tests for Kubernetes IPC commands (6 tests)
- All 332 Rust tests passing
- All 98 frontend tests passing
- TypeScript type checks passing
- Project builds successfully in release mode
- Committed and pushed to feature/kubernetes-management branch
- Command injection vulnerability fixed with regex validation and max length check (253 chars)
- stop_port_forward and shutdown_port_forwards properly kill kubectl child processes via async child management
- Temp file cleanup implemented with RAII TempFileCleanup struct created before std::fs::write
- discover_pods now parses actual kubectl JSON output
- ChildWaitHandle implemented with background task for waiting on kubectl child
- PortForwardSession uses Arc<TokioMutex<Option<Child>>> for async-safe child management
- Port-forward uses kubectl's dynamic port binding (0) instead of TcpListener
- Added shutdown_port_forwards command for app shutdown cleanup
- Added cleanup effect in App.tsx to call shutdownPortForwardsCmd on unmount
- Database CRUD operations for clusters and port_forwards added to db.rs
- validate_resource_name uses lazy_static! for cached Regex to prevent ReDoS
- Cluster struct updated to store kubeconfig_content directly instead of kubeconfig_id
- Cluster model in db/models.rs updated to use kubeconfig_content field
- load_clusters and load_port_forwards commands registered in lib.rs
- Temp file cleanup moved to background task in ChildWaitHandle to ensure cleanup after kubectl completes
- Unused child_id field removed from ChildWaitHandle
- Command validation moved to beginning of start_port_forward before any operations
- Fixed lint errors: removed unused imports, fixed React hooks order, updated type annotations
- Updated eslint.config.js to properly configure file patterns

+# Kubectl Runtime Implementation Fix Plan
+
+## Issues Identified
+
+### CRITICAL BLOCKERS
+
+1. **std::mem::drop(child.kill()) ignores async Kill future** (kube.rs:532-540)
+   - `child.kill()` returns a `Future<Output = ()>` that must be awaited
+   - Current code drops the future without awaiting, leaving process in undefined state
+
+2. **Arc<Mutex<Child>> is not Send/Sync** (kube.rs:500, portforward.rs:14)
+   - `tokio::process::Child` is NOT `Send` or `Sync`
+   - `std::sync::Mutex` provides no `Send` guarantee for its contents
+   - Cannot safely share `Child` across async boundaries
+
+3. **No error propagation from kubectl subprocess** (kube.rs:530-531, 548)
+   - stderr/stdout from kubectl subprocess are completely ignored
+   - No way to detect kubectl errors or capture error messages
+   - Session state never updated with error information
+
+4. **std::sync::Mutex<Child> in PortForwardSession** (portforward.rs:23, 87, 103)
+   - Same issues as #2, plus `Drop` implementation can't await
+
+### WARNING ISSUES
+
+5. **validate_resource_name regex not cached** (kube.rs:303-304)
+   - `Regex::new()` called on every validation call
+   - Should use `lazy_static!` or `once_cell::sync::Lazy<Regex>`
+
+6. **Temp kubeconfig not cleaned on all paths** (kube.rs:524-534)
+   - `TempFileCleanup` struct exists but only used in `discover_pods`
+   - `start_port_forward` and `test_cluster_connection` don't clean up
+
+7. **Tests don't verify subprocess exists** (cluster_management.rs:278-290)
+   - No mock Command framework or subprocess verification
+
+## Implementation Plan
+
+### Phase 1: Core Architecture Fix
+
+**Goal:** Replace unsafe `Arc<Mutex<Child>>` with proper async-safe storage
+
+**Approach:**
+1. Store `JoinHandle<()>` instead of `Child` directly
+2. Spawn background task to wait on child and update session state
+3. Use `tokio::sync::Mutex` for session state access
+4. Implement proper async cleanup in `stop()` and `Drop`
+
+### Phase 2: Error Handling
+
+**Goal:** Capture and propagate kubectl subprocess errors
+
+**Approach:**
+1. Background task waits on child and captures exit status
+2. Update session state with error messages on failure
+3. Store stderr/stdout for debugging
+4. Propagate errors to UI via session status
+
+### Phase 3: Cleanup Improvements
+
+**Goal:** Ensure temp files are always cleaned up
+
+**Approach:**
+1. Use RAII pattern consistently across all functions
+2. Add cleanup hooks for panic/early-return paths
+3. Store temp path in session struct for later cleanup
+
+### Phase 4: Regex Caching
+
+**Goal:** Cache compiled regex for performance
+
+**Approach:**
+1. Define `static ref NAME_PATTERN_REGEX: Lazy<Regex> = ...`
+2. Replace `Regex::new()` call with static reference
+
+## Files to Modify
+
+1. `src-tauri/src/kube/portforward.rs` - Core architecture fix
+2. `src-tauri/src/commands/kube.rs` - Integration and fixes
+3. `src-tauri/tests/integration/kube/cluster_management.rs` - Add subprocess verification
+4. `src-tauri/tests/integration/kube/port_forwarding.rs` - Add subprocess verification
+
+## Test Strategy
+
+After fixes:
+1. Run `cargo test --lib` - expect 325 tests passing
+2. Run `cargo clippy` - expect no warnings
+3. Run type check: `npx tsc --noEmit` - expect no errors
+4. Run frontend tests: `npm run test:run` - expect 98 tests passing
