Pull request overview
This PR tightens how batch processor options apply OTEL_BSP_* environment/config values by only applying values that pass validation, preventing invalid inputs from overriding defaults.
Changes:
- Added centralized validation/application helper for batch processor option values.
- Updated trace and logs option constructors to defer applying values until after validation.
- Updated/added unit tests to reflect validated behavior and to use scoped environment variables for trace tests.

(truncated) ## 1.16.0-rc.1 The following changes are from the previous release [1.15.3](https://github.com/open-telemetry/opentelemetry-dotnet/releases/tag/core-1.15.3). * NuGet: [OpenTelemetry v1.16.0-rc.1](https://www.nuget.org/packages/OpenTelemetry/1.16.0-rc.1) * Stop validating View-provided metric stream `Name` against the instrument name syntax, per [spec clarification](open-telemetry/opentelemetry-specification#5094). ([#7300](open-telemetry/opentelemetry-dotnet#7300)) * Fix incorrect validation of `OTEL_BSP_*` and `OTEL_BLRP_*` environment variables. ([#7187](open-telemetry/opentelemetry-dotnet#7187)) * Fix observable instrument callbacks running once per reader instead of once per collection cycle. ([#7188](open-telemetry/opentelemetry-dotnet#7188)) * Added exception safety for user-supplied `ExemplarReservoir` implementations. Exceptions thrown from `Offer` are now caught and logged rather than propagating out of `Counter.Add`/`Histogram.Record`. ([#7277](open-telemetry/opentelemetry-dotnet#7277)) * Update `OpenTelemetrySdkEventSource` to support the W3C randomness flag. ([#7301](open-telemetry/opentelemetry-dotnet#7301)) * Added `ObservedTimestamp` property to `LogRecord`. ([#6979](open-telemetry/opentelemetry-dotnet#6979)) * **Breaking Change** Explicit histogram boundaries no longer allow more than 10 million values. ([#7165](open-telemetry/opentelemetry-dotnet#7165)) * Fixed a circular reference which could cause a `LoggerProvider` to fail to resolve when one of its dependencies depends on `ILogger` or `ILoggerFactory`. As part of this fix the `LoggerProvider` resolved from dependency injection is now created lazily when the first logger is created rather than when `ILoggerProvider` or `ILoggerFactory` is resolved. A consequence is that any invalid configuration now surfaces when the first log record is written instead of when the logging services are resolved. ([#7308](open-telemetry/opentelemetry-dotnet#7308)) See [CHANGELOG](https://github.com/open-telemetry/opentelemetry-dotnet/blob/core-1.16.0-rc.1/src/OpenTelemetry/CHANGELOG.md) for details. * NuGet: [OpenTelemetry.Api v1.16.0-rc.1](https://www.nuget.org/packages/OpenTelemetry.Api/1.16.0-rc.1) * **Experimental (pre-release builds only):** Add support for using environment variables as context propagation carriers. ([#7174](open-telemetry/opentelemetry-dotnet#7174)) * Fix `BaggagePropagator` to correctly follow Key and Value Encoding rules as per ... (truncated) ## 1.16.0-beta.1 The following changes are from the previous release [1.15.3-beta.1](https://github.com/open-telemetry/opentelemetry-dotnet/releases/tag/coreunstable-1.15.3-beta.1). * NuGet: [OpenTelemetry.Exporter.Prometheus.AspNetCore v1.16.0-beta.1](https://www.nuget.org/packages/OpenTelemetry.Exporter.Prometheus.AspNetCore/1.16.0-beta.1) * Fixed scrape response cache freshness using monotonic time so it is not affected by NTP system clock adjustments. ([#7253](open-telemetry/opentelemetry-dotnet#7253)) * **Breaking Change** Removed `DisableTimestamp` property from `PrometheusAspNetCoreOptions`. ([#7176](open-telemetry/opentelemetry-dotnet#7176)) * Fixed the serialization of `NaN`, `PositiveInfinity`, and `NegativeInfinity` values in Prometheus metrics to be compliant with the specification. ([#7179](open-telemetry/opentelemetry-dotnet#7179)) * Fixed loss of precision when serializing `double` and `float` values in Prometheus metrics to be compliant with the specification by using 17 significant digits to represent such values. ([#7179](open-telemetry/opentelemetry-dotnet#7179)) * Fix non-ASCII characters in metric names and unit strings not being sanitized correctly during Prometheus serialization. ([#7184](open-telemetry/opentelemetry-dotnet#7184)) * Fix case where reader tracking could be reset while readers were still active. ([#7190](open-telemetry/opentelemetry-dotnet#7190)) * Improve `Accept` header handling for format negotiation so OpenMetrics is selected correctly by considering whitespace and `q` weights. ([#7208](open-telemetry/opentelemetry-dotnet#7208)) * Emit OpenMetrics exemplars for counters and histogram buckets. ([#7222](open-telemetry/opentelemetry-dotnet#7222)) * Fix incorrect handling of untyped metrics when using OpenMetrics format. ([#7219](open-telemetry/opentelemetry-dotnet#7219)) * Fix Prometheus/OpenMetrics serialization to emit metric and label names containing `_` instead of dropping them and prefixing leading digits. Invalid characters are replaced with `_` instead of being dropped. ([#7209](open-telemetry/opentelemetry-dotnet#7209)) * Add `escaping=underscores` to the `Accept` header handling for content negotiation so OpenMetrics are handled correctly. ([#7209](open-telemetry/opentelemetry-dotnet#7209)) * Omit histogram `_sum` and `_count` in OpenMetrics when negative bucket thresholds are present.
