The handler-signature `query (vars) [terms] where …` clause and the
`reads`/`writes` clauses overlapped the `@Queries` annotation (and each other):
two ways to attach a query to a handler. Consolidated on the decorator.
- parse_system no longer parses `query`/`reads`/`writes` clauses; it keeps the
postfix `@anno(...)` channel and `phase`. A handler's query is the prefix
`@Queries(these: [...], on: Model)` annotation. Data-access hints are now
`@Reads(...)`/`@Writes(...)` — absorbed by the generic annotation skipper,
same parse-and-reserve status the old clauses had.
- The inline `for (…) in query […] where …` statement is unchanged and still
covers cross-property constraints / multiple kind filters. `query` stays a
keyword there (now dispatched via is_id so the vocabulary check sees it).
examples/hello.ludic and examples/qdecl.ludic migrated to `@Queries` (qdecl now
demonstrates a per-property constraint + `on:` tag); outputs unchanged
(4 4 10 3 / 0 3 -2). LANGUAGE.md handler sections rewritten. Vocabulary: drop
`reads`/`writes` from CLAUSE (ludic_syntax.h, grammar, LudicTokens.kt).
Reseeded (21931 lines); C-free fixpoint holds; goldens identical; 17/17;
vocab + doc-fences clean.
