shoney.arickathil d4bfee9745 feat(compiler): language-integrated query — scan/where/select (9b slice)

- Ast.Query node + parser: `from <v> in <src> where* [group..into] [order
  by] [take] select <e>`, positional `from` trigger so it stays a usable
  identifier; select stays grammar-owned (no DbStub conflict)
- typecheck: range var bound to the source table class; a table-class
  value is its row id at runtime but TYPES as the class, so `e.field`
  checks against the class fields; result is `multi <select-type>`;
  group/order/take/navigation diagnosed WO-E250 not-yet (honest edge)
- emit: `from/where/select` lowers to a bytecode LOOP over DB_SCAN's
  materialized id list — DB_GET_FIELD per column read, where-guards skip
  the push, select projects, result is a fresh multi; no plan tree, no
  SQL text (disassembly-provable)
- field access on a @table-class value routes to DB_GET_FIELD instead of
  GETF (clsrec.cr_is_table + is_table_class); non-table classes unchanged
  so log-watcher is unaffected
- the ASan-caught bug kept in a comment: a table-class query element is a
  SCALAR id, not an OWNED pointer — tagging the result multi OWNED dropped
  an id as a pointer (SEGV in wo_drop_obj)
- fixture run/db-query-scan (where-filter + select-whole + select-field);
  oop-e2e 74/0, woc-test 566/0, log-watcher 7/0
- SLICE scope: group-by aggregation, order/take, and ref/backlink
  navigation are the next chunk (employee report/staff/raise need them)
