/**
 * `ArgMatcher` — a small, serializable matcher over a tool call's `input`.
 *
 * Shared by the check vocabulary (`toolWith` / `notTool` in `src/check.ts`) and
 * the tool-interception seam (`src/tool-intercept.ts`), so "did the agent call
 * this tool with these arguments?" means the same thing whether you're *asserting*
 * on a captured call or *intercepting* one before it runs. Pure + model-free.

/**
 * A declarative matcher over a tool call's `input`, keyed by **dot-path** (e.g.
 * `"body.prompt"`). Each value is matched against the value at that path: a
 * `RegExp` is a pattern over the stringified value (use this for "contains"), and
 * a `string`/`number`/`boolean` is an **exact** match (use this for "equals", e.g.
 * a push target). All keys must match (AND). Serializable, so anything carrying
 * one still round-trips through `toJSON`.
