Module platform 

Platform boundary for Windows/POSIX-sensitive operations.

This module centralizes platform-specific behavior so runtime code can import from crate::platform rather than scattering #[cfg] branches.

Boundary rule: use crate::platform for

• Filesystem-safe name generation from external identifiers
• Global cache root resolution
• Cross-process file locks
• Durable file writes (atomic writes)
• Generated directory replacement and cache publication
• External process invocation (git)

What stays direct: PathBuf joins under resolved roots, fs::read/read_dir, config reads, content hashing, domain validation in SourceSubpath.
