Chameleon

Fixed

• jsx-presence-mismatch (a block-eligible ERROR) no longer fires on a .ts /
  .mts / .cts file. Those extensions cannot legally contain JSX -- only
  .tsx / .jsx can -- so any angle brackets are generics, comparisons, or a
  template-string SVG (`<svg>...</svg>`). A nested template literal could
  leak </svg> past the string scan and be misread as JSX, hard-flagging
  conforming code with "move JSX to a component file. Fix these." jsx_present
  is now forced False for these extensions where dimensions are extracted, with
  zero signal loss (JSX detection on .tsx / .jsx is unchanged). Found and
  verified via real usage.
• then-without-catch no longer flags a .then whose promise rejection is
  delegated or handled elsewhere: a RETURNED promise (return x.then(...)), an
  arrow-returned one (() => import('./m').then(...)), an AWAITED/voided one, or
  a .then(...) immediately followed by a chained .catch(...) on a nearby line.
  These are the dominant real patterns; flagging them was a false positive (the
  noisiest advisory in practice). A truly bare statement-level x.then(fn) with
  no rejection handler still fires.
