Draft

@rahulchhabria — draft ready for review. Publish via changelog.sentry.dev when ready.

• rustls-no-provider feature flag — use the rustls transport with a custom crypto provider instead of the default, useful for environments with strict crypto requirements.
• Metrics enabled by default — ClientOptions::enable_metrics now defaults to true, aligning with other Sentry SDKs. Still requires the metrics feature flag at compile time.
• Attachment envelope headers fixed — headers are now correctly serialized as JSON, resolving an encoding bug that could corrupt attachment metadata.
