[Release] Increase version to 3.4.5

[Jackson Weber (JacksonWeber)]

Prepares the next patch release following microsoft/ApplicationInsights-JS#2756.

• Bumps SDK packages to 3.4.5 and updates independently versioned packages, internal dependencies, and Rush package hashes.
• Adds release notes for internal SDK Stats, dedicated ingestion, dynamic configuration, feature throttling, and opt-out behavior.
• Updates the CDN version table and performance-test version.

Lint completed with Node 22. Release versions and Rush package hashes were checked. The main SDK bundles and declarations were generated, and the isolated 1DS core build passed.

Full clean-build validation remains incomplete. Windows cleanup failed on junction traversal and an open log directory. The subsequent monorepo rebuild was interrupted, and its 1DS minifier failure passed on an isolated retry.
