2f16ba0362 fix: Windows test stability - scenario_09 race condition and IOSystemStress crash 
- Fix scenario_09_threadsafety: Add writerDone flag to ensure writer thread
  finishes before clear() is called, preventing race condition

- Fix IntraIO destructor: Call removeInstance() to unregister from
  IntraIOManager and prevent dangling pointer access

- Fix IOTestEngine destructor: Inline cleanup instead of calling unloadModule()
  which was modifying the map while iterating (undefined behavior)

- Fix CTest macro: Use WORKING_DIRECTORY with PATH environment variable
  instead of cmake -E chdir for proper Windows DLL loading

edf4d76844 fix: Windows MinGW CTest compatibility - DLL loading and module paths 
- Add cmake -E chdir wrapper for CTest on Windows to resolve DLL loading
- Auto-copy MinGW runtime DLLs to build directories during configure
- Fix module paths in integration tests (.so -> .dll for Windows)
- Update grove_add_test macro for cross-platform test registration

Tests now pass: 55% (16/29) on Windows MinGW

98acb32c4c fix: Resolve deadlock in IntraIOManager + cleanup SEGFAULTs 
- Fix critical deadlock in IntraIOManager using std::scoped_lock for
  multi-mutex acquisition (CrossSystemIntegration: 1901s → 4s)
- Add std::shared_mutex for read-heavy operations (TopicTree, IntraIOManager)
- Fix SEGFAULT in SequentialModuleSystem destructor (logger guard)
- Fix SEGFAULT in ModuleLoader (don't auto-unload when modules still alive)
- Fix iterator invalidation in DependencyTestEngine destructor
- Add TSan/Helgrind integration for deadlock detection
- Add coding guidelines for synchronization patterns

All 23 tests now pass (100%)

3923e3cbbe feat: Add StillHammer Logger & IntraIO batching (WIP) 
- Add StillHammer Logger library (external/StillHammer/logger/)
  * Elegant wrapper around spdlog (1 line instead of 10+)
  * Auto-organize logs by domain: logs/domain/component.log
  * Snake_case conversion: NetworkIO → network_io.log
  * Thread-safe, zero-overhead, includes demo and tests

- Add IntraIO low-frequency batching infrastructure
  * BatchBuffer structure for message accumulation
  * batchFlushLoop() thread for periodic flushing
  * Pattern matching lambda for detecting low-freq subscriptions
  * WIP: test_11 scenario 4 still failing (100 batches instead of ~2)

a846ed26d7 feat: Add StillHammer TopicTree for O(k) topic routing 
Replace O(n×m) regex-based pattern matching with O(k) hierarchical
hash map lookup in IntraIOManager.

## Changes

**New: StillHammer/topictree library**
- Header-only C++17 template library
- Zero-copy topic parsing with string_view
- Wildcards: `*` (single-level), `.*` (multi-level)
- Thread-safe with mutex protection
- Comprehensive test suite (10 scenarios)

**Modified: IntraIOManager**
- Replace RouteEntry vector + regex with TopicTree
- Batched logging (every 100 messages) to reduce spam
- O(k) lookup where k = topic depth (~3 segments)

## Performance

- Before: O(n patterns × m regex ops) per message
- After: O(k topic depth) per message
- Typical gain: ~33x faster for 100 patterns, depth 3

## Tests

✅ test_11 (scenarios 1-3): Basic routing, pattern matching, multi-module
✅ test_12: DataNode integration (all 6 tests pass)
⚠️  test_11 (scenario 4+): Batching feature not implemented (out of scope)
