/**
 * Deterministic SHA256 hashing for asset content.
 *
 * One algorithm shared by:
 *   - glob discovery (`discover.ts`)
 *   - author-shipped manifest discovery (`discover-manifest.ts`)
 *   - virtual-tree discovery (`tree-entries.ts`, via its own copy using async fetch)
 *
 * Hashing rule: files sorted alphabetically. For each file feed
 *   `path` + `\0` + `content` + `\0`
 * into SHA256. Yields the same hash regardless of OS or filesystem ordering.
 *
 * Files that are referenced by the file filter but absent on disk are skipped
 * (non-fatal): they typically represent optional companion files like
 * `validator.py` that may not exist for every asset. The author-manifest path
 * surfaces missing files as a hard error before reaching the hash step, so
 * this only matters for the glob discovery code path.
