/**
* What the Coach offers the model, and where each call lands.
*
* Two halves, both pinned to committed files:
*
* 1. The tool definitions a tool-mode turn hands the model
* (`COACH_TURN_TOOL_DEFS`): names, descriptions, parameter schemas and
* their order. They are the stable prompt-cache prefix, so a byte that
* moves is a cache miss for every person.
* 2. The dispatch table: for every tool name the executor knows, the call
* reaches the executor that validates with that tool's own schema. Each
* name is called with arguments no schema accepts (`[]`), and the
* annotation the executor writes names the tool that refused them. A name
* routed to the wrong executor, or dropped from the table, changes the
* record. The snapshot builder throws, so the one executor that accepts
* any arguments (`get_illness_recovery`) answers through the catch.

/**
* The advertised tool list, byte for byte.
*
* What a host sees from `tools/list` is the contract: the names, titles,
* descriptions, input and output schemas, annotations and their order. A
* client caches it, a model is prompted with it, a directory reviews it. This
* pins the whole list as the wire carries it, read through a real SDK client
* over an in-memory transport, so a refactor of where the definitions live
* cannot change a byte of it unnoticed.
*
* Two sessions: a write-scoped one (every tool, read and write) and a
* read-only one (the read registry alone, in its order).
