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)

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)
