* feat(obs): unify metrics initialization and fix exporter move error
- Fix Rust E0382 (use after move) by removing duplicate MetricExporter consumption.
- Consolidate MeterProvider construction into single Recorder builder path.
- Remove redundant Recorder::builder(...).install_global() call.
- Ensure PeriodicReader setup is performed only once (HTTP + optional stdout).
- Set global meter provider and metrics recorder exactly once.
- Preserve existing behavior for stdout/file vs HTTP modes.
- Minor cleanup: consistent resource reuse and interval handling.
* update telemetry.rs

* Refactor telemetry initialization and environment functions ordering
- Reorder functions in envs.rs by type size (8-bit to 64-bit, signed before unsigned) and add missing variants like get_env_opt_u16.
- Optimize init_telemetry to support three modes: stdout logging (default error level with span tracing), file rolling logs (size-based with retention), and HTTP-based observability with sub-endpoints (trace, metric, log) falling back to unified endpoint.
- Fix stdout logging issue by retaining WorkerGuard in OtelGuard to prevent premature release of async writer threads.
- Enhance observability mode with HTTP protocol, compression, and proper resource management.
- Update OtelGuard to include tracing_guard for stdout and flexi_logger_handles for file logging.
- Improve error handling and configuration extraction in OtelConfig.
