//! v3.31 c1 — `ResolverContext` pub + `resolve_selector_compiled` /
//! `resolve_selector_all_compiled` API surface unit tests.
//!
//! Validates the four entry-point cases callers of the new pub API must
//! handle:
//! 1. plain hit — non-regex `Pattern`, single tree match
//! 2. regex hit — regex `Pattern`, single tree match (cache prepass
//!    builds a `CompiledPattern` once, looked up via `ctx.pattern`)
//! 3. miss — selector compiles but matches no node in the tree
//! 4. invalid regex — `ResolverContext::new` returns `None` at compile
//!    time (matches `resolve_selector` silent-`None` semantic; caller
//!    can branch on `?` short-circuit)
