Greptile Summary

This PR updates Appwrite's documentation and default configuration to reflect the availability of two new runtimes: Dart 3.11 (for Functions) and Flutter 3.41 (for both Functions and Sites). All changes are content/documentation updates with no application logic involved.

Key changes:

• New changelog entry (2026-04-02.markdoc) announcing Dart 3.11 and Flutter 3.41 on Appwrite Cloud
• dart-3.11 and flutter-3.41 added to both "All runtimes" and "Available on Cloud" tabs on the Functions runtimes page
• Self-hosting configuration examples updated to reference the new runtime versions (dart-3.11 in the Functions guide, flutter-3.41 in the Sites guide)
• Default _APP_SITES_RUNTIMES in static/install/env bumped from flutter-3.29 to flutter-3.41

All changes are internally consistent and properly cross-referenced across the affected files.

Confidence Score: 5/5

• Safe to merge — all changes are documentation and default config updates with no application logic affected
• No P0 or P1 issues found. The changes are straightforward content updates that are consistent across all modified files. The only previously-flagged concern (changelog not explicitly mentioning Flutter 3.41 for Functions) was already noted in prior review threads.
• No files require special attention
