chore: patch release 18.0.1

[ChiragAgg5k]

Summary

• Bumps version to 18.0.1 (package.json, package-lock.json, Formula/appwrite.rb)
• Adds changelog entry for the patch

The 18.0.0 publish workflow failed at the "Update Homebrew formula checksums" step because it ran with the old \Q...\E regex syntax. The fix landed on master in #297 but the workflow used the YAML from the 18.0.0 tag.

This patch release will re-trigger the publish workflow with the corrected regex so Homebrew checksums get updated properly.

Test plan

• Merge PR
• Create 18.0.1 GitHub release targeting master
• Verify publish workflow completes successfully including Homebrew formula update

Greptile Summary

This is a patch release bumping the version to 18.0.1 across package.json, package-lock.json, and Formula/appwrite.rb, along with a CHANGELOG entry. The sole purpose is to re-trigger the publish workflow with the Homebrew checksum regex fix that landed in #297, since the 18.0.0 workflow ran against the old tag's YAML. The sha256 placeholder values in Formula/appwrite.rb are intentionally zeroed out and will be replaced by release automation.

Confidence Score: 5/5

• This PR is safe to merge — it's a minimal, consistent version bump with no logic changes.
• All four changed files are version/metadata updates only. Versions are consistent across package.json, package-lock.json, and the Homebrew formula. The SHA256 placeholders in the formula are intentional and handled by the publish workflow. No functional code was modified.
• No files require special attention.

Important Files Changed

package.json	Version bumped from 18.0.0 to 18.0.1; no other changes.
