Ghost stack 2/6 — Surface model build-out (Phases 1–8)

+Add `ghost.binding/v1` (`.ghost.bind.yml`) and the path road: a repo path
+resolves to the surface that owns it (directory-default binding or explicit
+declaration), and `ghost gather --path <file>` composes that surface's slice.
+The contract still carries no paths — bindings own all path matching.

+Add fingerprint grounding to `ghost checks`: for each touched surface, emit the
+*why* (principles and experience contracts) and the *what good looks like*
+(patterns and exemplars with paths), drawn from that surface's slice and
+inherited from its ancestors. A flagged check can now cite the design intent it
+serves and point at an exemplar. Use `--no-grounding` for relevance only.

+Add `ghost gather <surface>`: compose a surface's context slice (its own placed

+parsed and linted but never executed by Ghost. Markdown files under a `checks/`

+Ghost can route and ground checks without owning a check engine.

+Add `ghost migrate`: transform a legacy `.ghost/` package onto the surface model

+`surface:`, and report (never guess) any node it cannot place unambiguously.

+Remove the absorbed and dead commands: `relay`, `stack`, `survey`, `diff`, and
+`describe`, along with the relay-only context modules and the `./relay` package
+export. Their intent now lives in the surface model — `gather` for context,
+`checks` for diff-routed governance, and bindings for path resolution. The skill
+bundle teaches the surface workflow.

+Retire the `child-wins-by-id` fingerprint merge (Leak E): nested `.ghost/`
+packages now bind paths to the root contract's surfaces instead of merging their
+own facets in. A path resolves to the single root contract, used as-is — a child
+package can no longer silently override or disable an inherited rule or check.
+The `stack` / `check` / `review` outputs expose `contract` instead of `merged`,
+and drop the `provenance.merge` field.

+Add surface-routed check relevance: `ghost checks --diff` resolves each changed
+path to its surface (via bindings) and selects the markdown checks governing the
+touched surfaces and their ancestors (the same inheritance as `gather`). Ghost
+selects and emits the relevant checks; it never runs them. A `checks/` directory
+in a package holds `ghost.check/v1` markdown checks.
