Users can now control logging verbosity through:
- YAML config file: log_level: "debug|info|warn|error"
- Environment variable: PULSE_SENSOR_PROXY_LOG_LEVEL
Default log level is set to "info" instead of debug, reducing verbose output.
Supported levels: trace, debug, info, warn, error, fatal, panic, disabled

Add support for configuring rate limits via config.yaml to allow
administrators to tune the proxy for different deployment sizes.
Changes:
- Add RateLimitConfig struct to config.go with per_peer_interval_ms and per_peer_burst
- Update newRateLimiter() to accept optional RateLimitConfig parameter
- Load rate limit config from YAML and apply overrides to defaults
- Update tests to pass nil for default behavior
- Add comprehensive config.example.yaml with documentation
Configuration examples:
- Small (1-3 nodes): 1000ms interval, burst 5 (default)
- Medium (4-10 nodes): 500ms interval, burst 10
- Large (10+ nodes): 250ms interval, burst 20
Defaults remain conservative (1 req/sec, burst 5) to support most
deployments while allowing customization for larger environments.

The name "temp-proxy" implied a temporary or incomplete implementation. The new name better reflects its purpose as a secure sensor data bridge for containerized Pulse deployments.
Changes:
- Renamed cmd/pulse-temp-proxy/ to cmd/pulse-sensor-proxy/
- Updated all path constants and binary references
- Renamed environment variables: PULSE_TEMP_PROXY_* to PULSE_SENSOR_PROXY_*
- Updated systemd service and service account name
- Updated installation, rotation, and build scripts
- Renamed hardening documentation
- Maintained backward compatibility for key removal during upgrades
