Refresh README badges and SDK list

[ChiragAgg5k]

Summary

• Replace the stale Travis build badge with active GitHub Actions status badges for CI and Twig linting.
• Update the Twitter social badge to an X badge linking to the current Appwrite X profile.
• Replace stale SDK support tables with generated targets that match example.php, including newer outputs such as Rust, GraphQL, Markdown, Agent Skills, Cursor Plugin, and Claude Plugin.

Testing

• git diff --check

No runtime tests were run because this is a README-only documentation update.

Greptile Summary

This is a README-only update that replaces the stale Travis CI and Twitter badges, removes the "WORK IN PROGRESS" notice, updates the quick-start code example to use the current raw-GitHub spec URL, adds a StaticSpec usage snippet, and rewrites the SDK support tables to match the actual targets in example.php (including Rust, GraphQL, Markdown, Agent Skills, Cursor Plugin, and Claude Plugin). All claims in the updated tables were verified against example.php and src/Spec/StaticSpec.php.

Confidence Score: 5/5

Safe to merge — documentation-only changes with no runtime impact.

All badge URLs reference existing workflows, code examples match actual class constructors and example.php, and SDK table entries are verified against the codebase. No logic or runtime code is modified.

No files require special attention.

Important Files Changed
