Organize gitignore and ignore local editor caches

[hawkff]

Summary

• organize .gitignore into labeled sections
• ignore Cursor project state via .cursor/
• ignore Kotlin local build/cache state via .kotlin/
• ignore macOS AppleDouble files that can break Android builds
• keep existing local/generated artifacts ignored

Validation

• git diff --check
• git check-ignore -v .cursor .kotlin .DS_Store ._foo .masterdnsvpn-build

Greptile Summary

This PR reorganizes .gitignore into clearly labeled sections and adds coverage for Cursor editor state (.cursor/), Kotlin build cache (.kotlin/), and macOS AppleDouble files (._*, __MACOSX/). Existing entries are preserved; directory patterns are normalized with trailing slashes, and the now-redundant .idea/deploymentTargetDropDown.xml entry is removed since .idea/ covers it.

• Adds .cursor/, .kotlin/, ._*, and __MACOSX/ to cover common developer environment artifacts not previously ignored.
• Trailing slashes added to directory entries so patterns explicitly match only directories.
• /nkmr and /external changed to /nkmr/ and /external/; these now match only directories at the repo root.

Confidence Score: 5/5

Safe to merge — purely additive .gitignore housekeeping with no tracked files affected.

The change only reorganizes and extends .gitignore. All new entries cover editor/OS/build artifacts that should never be committed, and the trailing-slash normalization on existing entries tightens directory matching in a harmless way for this project.

No files require special attention.

📝 Walkthrough

Walkthrough

The .gitignore file is rewritten to expand and reorganize ignore rules across six functional sections: macOS filesystem metadata (.DS_Store, ._*, __MACOSX/), IDE/editor directories (.idea/, .vscode/, .cursor/, *.iml), Gradle/Kotlin build state (.gradle/, .kotlin/, build/), native/Android build outputs (/captures/, .externalNativeBuild/, .cxx/, and project-specific paths), local configuration and generated artifacts (local.properties, /app/..., /service_account_credentials.json, /nkmr/), and an /external/ section.

Changes

.gitignore Normalization

Layer / File(s)	Summary
Ignore rule additions and restructuring .gitignore	Rewrites the file to add macOS metadata patterns, IDE/editor directory patterns, Gradle/Kotlin and nested build output rules, native/Android build output paths, local config and generated app artifact entries, a service account credentials entry, and an /external/ section; removes the prior narrow .idea/deploymentTargetDropDown.xml entry.

Poem

A rabbit hops through tangled trees,
Sweeping .DS_Store leaves with ease.
.idea/, .cursor/, .vscode/ too—
All tucked away from the reviewer's view.
Build outputs buried, credentials hidden tight,
The .gitignore den is tidy tonight! 🐇✨
