[vibe in progress] Migrate to inline type annotations

[sl0thentr0py]

The codebase was migrated from comment-based to inline type annotations following PEP 484. This involved:

• Core SDK files: sentry_sdk/session.py, sentry_sdk/feature_flags.py, sentry_sdk/_lru_cache.py, sentry_sdk/_werkzeug.py, sentry_sdk/logger.py, sentry_sdk/worker.py, sentry_sdk/scrubber.py, sentry_sdk/monitor.py, sentry_sdk/_log_batcher.py, sentry_sdk/client.py, and sentry_sdk/tracing.py were fully migrated. sentry_sdk/serializer.py was intentionally skipped due to its complexity.
• Integration files: 16 major integration files were migrated, including sentry_sdk/integrations/trytond.py, sentry_sdk/integrations/typer.py, sentry_sdk/integrations/statsig.py, sentry_sdk/integrations/unleash.py, sentry_sdk/integrations/serverless.py, sentry_sdk/integrations/socket.py, sentry_sdk/integrations/atexit.py, sentry_sdk/integrations/pure_eval.py, sentry_sdk/integrations/graphene.py, sentry_sdk/integrations/fastapi.py, sentry_sdk/integrations/chalice.py, sentry_sdk/integrations/quart.py, sentry_sdk/integrations/beam.py, sentry_sdk/integrations/langchain.py, sentry_sdk/integrations/asgi.py, sentry_sdk/integrations/flask.py, and sentry_sdk/integrations/aws_lambda.py.
• Migration tooling: scripts/migrate_type_annotations.py was created for automated conversions and analysis. MIGRATION_GUIDE.md and MIGRATION_STATUS.md were added for documentation and progress tracking.
• Correction: An initial unintended functional change in sentry_sdk/feature_flags.py was reverted to ensure strict adherence to type annotation migration.

The changes standardize type hinting, improving IDE support, type safety, and developer experience across the core SDK and key integrations.
