refactor(Mountain/Initialize): Enhance build modules with feature flags, config, and telemetry

This commit significantly refactors the `RuntimeBuild` and `StateBuild` initialization modules within `Mountain`'s binary subsystem to support advanced build profiles, structured logging, and OpenTelemetry integration.

**RuntimeBuild.rs:**
- Introduces a `SchedulerConfig` struct to allow flexible configuration of the Echo scheduler's worker count and logging level.
- Adds `BuildWithConfig` to enable custom scheduler instantiation (e.g., single-threaded for debugging).
- Implements feature-gated logging (Debug/Development) and telemetry initialization hooks.
- Includes unit tests for scheduler creation scenarios.

**StateBuild.rs:**
- Refactors `Build` to accept a `MountainEnvironment` argument for dependency injection, replacing the previous direct workspace folder manipulation.
- Introduces `StateBuildConfig` to control validation strictness and verbosity based on build features (e.g., `Debug` enforces strict validation).
- Adds OTEL span tracing around the state initialization lifecycle when the `Telemetry` feature is enabled.
- Includes a `ValidateCapabilities` stub for future environment health checks and `BuildMinimal` for test isolation.

These changes improve the robustness of the application startup sequence, providing better visibility into the initialization process and allowing for environment-specific tuning (e.g., limiting workers for debug builds).
