### Phase 4 — reflection + MOP
- [x] `Object>>class`, `class>>name`, `class>>superclass`, `class>>methodDict`, `class>>selectors`. `class` is universal in `st-primitive-send` (returns `Metaclass` for class-refs, the receiver's class otherwise). Class-side dispatch gains `methodDict`/`classMethodDict` (raw dict), `selectors`/`classSelectors` (Array of symbols), `instanceVariableNames` (own), `allInstVarNames` (inherited + own). 26 tests in `lib/smalltalk/tests/reflection.sx`.
- [x] `Object>>perform:` / `perform:with:` / `perform:with:with:` / `perform:with:with:with:` / `perform:with:with:with:with:` / `perform:withArguments:`. Universal in `st-primitive-send`; routes back through `st-send` so user methods, primitives, super, and DNU all still apply. Selector arg can be a symbol or string (we `str` it). 10 new tests in `lib/smalltalk/tests/reflection.sx`.
- [ ] `Object>>respondsTo:`, `Object>>isKindOf:`, `Object>>isMemberOf:`
- [x] `Object>>respondsTo:`, `Object>>isKindOf:`, `Object>>isMemberOf:`. Universal in `st-primitive-send`. `respondsTo:` searches user method dicts (instance- or class-side based on receiver kind); native primitive selectors aren't enumerated, documented limitation. `isKindOf:` walks `st-class-inherits-from?`; `isMemberOf:` is exact class equality. 26 new tests in `reflection.sx`.
- [ ] `Behavior>>compile:` — runtime method addition
- [ ] `Object>>becomeForward:` (one-way become; rewrites the class field of `aReceiver`)
- [ ] Exceptions: `Exception`, `Error`, `signal`, `signal:`, `on:do:`, `ensure:`, `ifCurtailed:` — built on top of SX `handler-bind`/`raise`
