Add the canonical .editorconfig verbatim from sneak/prompts. Merge secret
(.env, .env.*, *.key, *.pem), OS (.DS_Store, Thumbs.db), editor (*.swp,
*.swo, *~, .idea/, .vscode/), and Go (*.log, *.out, *.test) patterns into
.gitignore while preserving the repo-specific entries. Remove the stale
.drone.yml ignore entry and the DRONE_COMMIT_SHA branch from bin/gitrev.sh,
left over from the Gitea Actions migration.
bin/gitrev.sh remains correct: the GITREV env path (used in the Docker
build) and the git describe fallback (Gitea Actions and local developers)
both still produce output. bin/gitrev.sh stays tracked despite /bin/, and
git status --ignored confirms no tracked file became ignored.
The canonical .editorconfig sets space/4 for [*]; Go files are tab-indented
via gofmt, which editorconfig does not govern. Taken verbatim per the issue.
