data-recording v1.1: Major rewrite of the synchronized real-time data recording system.

Browse Source 
Application (v1.1):
- Generic N-node architecture replacing hardcoded gNB/UE structure
- Node-based JSON config with per-node shared memory paths
- Thread pool with barrier sync for multi-node recording
- Frame/slot-based message grouping in read_and_store_tracer_messages()
- Robust cleanup via atexit and signal handlers
- Remove v1.0 legacy application

Shared Memory Interface (new):
- System V shared memory attach/detach/remove with ftok-based keys
- Structured binary read/write for tracer control messages
- Frame/slot-aware data reading with configurable timeout

Config Interface:
- JSON-based config with node definitions (id, type, shared_mem_config)
- Per-node tracer message parsing and index resolution

SigMF Interface:
- Timestamp refactor: Unix epoch sec/nsec with nanosecond precision
- Wireless parameter mapping via YAML-driven parameter map
- System components metadata (TX/channel/RX) in SigMF annotations

Sync Service:
- Generic multi-node sync replacing 2-node sync
- Frame-wrap-aware comparison (1024-frame wrap)

Wireless Parameters Mapper (new):
- YAML-driven OAI-to-SigMF parameter mapping
- 5G NR metadata derivation (DMRS, modulation, link direction)
