• fix(hooks): stop pre/post Bash dispatcher from echoing the input event (#2240)

  runHooks() returned the unmodified raw stdin (the PreToolUse/PostToolUse
  input event) on stdout whenever no sub-hook produced additionalContext.
  Claude Code parses a hook's stdout as JSON and validates it against the
  hook-output schema, so echoing the input object
  ({session_id, hook_event_name, tool_name, tool_input, ...}) fails with
  "Hook JSON output validation failed — (root): Invalid input" on nearly
  every Bash command.
  
  Track whether a sub-hook deliberately set stdout (string / {stdout}, e.g.
  GateGuard) via a rawModified flag and emit '' in the pass-through case
  instead of the echoed input. Preserves GateGuard pass-through and
  block-no-verify's exit-2 blocking.
  
  Update the three dispatcher tests that codified the buggy echo behavior to
  expect empty stdout, and add a regression test for a plain pass-through
  command.
  
  Fixes #2239
