Add sampleRate option to SessionRecordingOptions that allows setting the session recording sample rate locally. When set, it takes precedence over the remote config. Validates that the value is between 0 and 1, logging a warning and falling back to remote config for invalid values. Also adds documentation comments to enable_recording_console_log and capture_performance.network_timing clarifying their relationship to session recording/replay features.

Extract _validateSampleRate method that validates the value is between 0 and 1, returning null for invalid/missing values with a warning log. Applied to both local config and remote config sampleRate values.

Problem
Users need the ability to configure the session recording sample rate locally in their SDK init config, rather than relying solely on remote configuration. This enables faster iteration and local testing without needing to update remote settings.
