Wire the `.gq` authoring surface that controls how a stored query is projected
as an MCP tool. All of it rides in the query source (content-addressed,
re-parsed at boot), so there is no cluster.yaml / catalog / serving-snapshot
plumbing — and it is orthogonal to Cedar `invoke_query` (presentation, not
authorization).
- Per-parameter `@description("…")` (leading the variable) → carried on
`Param.description`, mapped through `param_descriptor`, and emitted on the
outer JSON-Schema property by `param_json_schema`, so it shows up in both the
MCP tool input schema and the `GET /queries` catalog.
- Query `@mcp(expose: <bool>, tool_name: "<name>")` → parsed into
`QueryDecl.mcp`; `StoredQuery::is_exposed()` / `effective_tool_name()` resolve
from it. `expose: false` hides a query from the agent surface (`tools/list`,
`stored_query_list`, run-by-name) while keeping it HTTP/service-callable.
- `@instruction` is folded into the MCP tool description (after `@description`),
so the agent-facing how/when-to-use guidance reaches `tools/list`.
- Removes the now-dead `RegistrySpec.{expose, tool_name}` fields (server + CLI);
`settings.rs` no longer hardcodes `expose: true`. Test helpers express
exposure by injecting `@mcp(expose: false)` into the source (the real path).
openapi.json regenerated: `ParamDescriptor` gains an optional `description`.
Tests: compiler parser (param @description, @mcp parse + duplicate rejection),
api-types schema_equivalence (description on the outer property), server mcp
(folded description + param docs + @mcp tool rename, list==call). Full
workspace gate green.
