v7.0.0

This is the v7 major release. It removes deprecated options and legacy code paths accumulated over the v6 line, modernizes the build, and ships a more reliable session manager.

• Smaller, faster bundle — dropping legacy browser shims and switching to ESM dynamic imports reduces the SDK footprint on modern browsers.
• Better privacy out of the box — safer default privacy settings mean less risk of capturing sensitive content without explicit configuration.
• More reliable sessions — modernized session manager with bug fixes, including around very short repetitive sessions.
• Higher-quality data — deterministic sampling (consistent decisions across products), aborted requests no longer polluting error metrics, and a new session_renewal view loading type to better understand session boundaries.
• A cleaner API — deprecated options and beta flags removed; what's left is the supported, stable surface going forward.

Migrating from v6:

• Follow the v6 → v7 migration guide in the Datadog documentation.
• For automated assistance, use the upgrade-browser-sdk-v7 Claude Code skill shipped in this repo.
