rajatnagda45 d7e463e476 fix(sql): extract triggers and link them to their table
Two defects left CREATE TRIGGER under-extracted:

- The create_trigger AST branch read the subject table off keyword_for, but the
  table follows ON ('... AFTER INSERT ON users'); FOR EACH ROW carries no table.
  So even a cleanly-parsed trigger got a node with no link to the table it fires
  on. Read the table after keyword_on instead.

- A trigger with a procedural body ('FOR EACH ROW BEGIN ... END') has no grammar
  production, so the statement lands in an ERROR node and only the whole-file
  routine-recovery scan can save it — but that scan's pattern matched only
  FUNCTION/PROCEDURE, so the trigger and its table were dropped entirely. Add a
  dedicated trigger-recovery pattern that mints the trigger node (label without
  (), since a trigger is not callable) and a triggers edge to the table named by
  the first ON after the trigger name. A trigger already recovered via the AST
  path is skipped to avoid a duplicate edge.

Added regression tests for both the clean EXECUTE FUNCTION form and the
procedural BEGIN...END form.
