refactor: use bare imports for Node.js built-ins

Replace all "node:" prefixed imports with bare imports across src/
for better compatibility and consistency.

Changed:
- "node:fs" → "fs"
- "node:path" → "path"
- "node:crypto" → "crypto"
- "node:os" → "os"
- "node:async_hooks" → "async_hooks"
- "node:child_process" → "child_process"
- "node:events" → "events"
- "node:http" → "http"
- "node:readline" → "readline"
- "node:stream" → "stream"
- "node:tty" → "tty"

Affected files (17):
- src/constants/platform.ts
- src/cover/code.ts
- src/dlx-binary.ts
- src/dlx-package.ts
- src/dlx.ts
- src/download-lock.ts
- src/env/rewire.ts
- src/fs.ts
- src/git.ts
- src/http-request.ts
- src/ipc.ts
- src/packages/isolation.ts
- src/paths.ts
- src/process-lock.ts
- src/spinner.ts
- src/stdio/mask.ts
- src/stdio/stdout.ts

Benefits:
- Consistent import style across the codebase
- Better compatibility with older bundlers
- Matches existing patterns in getFs(), getPath() helpers
