/** Strip the hashline `[path#TAG]` wrapper from a write/edit target so the inner
 *  filesystem path drives both authorization and resolution. Only unwraps inputs
 *  that match the strict hashline header shape (`[path]` or `[path#XXXX]` with a
 *  4-hex tag); anything else returns the original string so the downstream
 *  resolver surfaces the real error. A valid tag disambiguates a `#` inside the
 *  path (yadm alt files: `conf.yaml##hostname.home`), matching the Rust
 *  tokenizer. Used by the plan-mode guard's `resolvePlanPath` and by callers
 *  (e.g. `write`) that make scheme/bridge-routing decisions before it runs. */
