Greptile Summary

This PR prepares the v0.64.4 release by bumping the Xcode project version across all 8 build configurations (build 83→84, marketing version 0.64.3→0.64.4), adding the full 0.64.4 section to CHANGELOG.md, and registering the new version's feature highlights in changelog-media.ts.

• Xcode project: All targets (main app, DockTile plugin, AppTests, AppUITests) in both Debug and Release configurations are consistently updated — no configuration is left on the old version.
• CHANGELOG.md: The new section documents 10 additions, 5 changes, and 26 fixes with PR links and contributor callouts. @lawrencecchen appears in the contributors list without an explicit PR attribution, consistent with the several un-linked fix entries that likely represent their contributions.
• changelog-media.ts: Four feature highlights for 0.64.4 are added with no hero image (the hero field is optional per the VersionMedia interface), matching the pattern of recent patch releases in the file.

Confidence Score: 5/5

All three files are release metadata only — no Swift source, runtime logic, or application behaviour is changed.

The change is limited to a version bump in the Xcode project, a changelog entry, and a static TypeScript data object for the docs site. Every build configuration in the project file was updated consistently, the changelog entry is well-formed and cross-referenced with PR numbers, and the TypeScript addition follows the exact same shape as every prior entry in the file. There is nothing here that could regress runtime behaviour.

No files require special attention.

Important Files Changed

Filename	Overview
CHANGELOG.md	Adds the 0.64.4 release section with Added, Changed, and Fixed entries plus contributor thanks; all items are well-formed and cross-referenced with PR links.
GhosttyTabs.xcodeproj/project.pbxproj	Version bump across all 8 build configurations: CURRENT_PROJECT_VERSION 83→84 and MARKETING_VERSION 0.64.3→0.64.4. Changes are purely mechanical and consistent across every target.
web/app/[locale]/docs/changelog/changelog-media.ts	Adds the 0.64.4 entry to changelogMedia with title and four feature highlight objects; no hero image provided (optional per interface), correctly inserted at the top of the Record.
