 - [x] Vendor a slice of Pharo `Kernel-Tests` and `Collections-Tests`. `lib/smalltalk/tests/pharo/kernel.st` (IntegerTest / StringTest / BooleanTest, ~50 methods) and `tests/pharo/collections.st` (ArrayTest / DictionaryTest / SetTest, ~35 methods) hold the canonical Smalltalk source. `lib/smalltalk/tests/pharo.sx` carries the same source as strings (the `(load …)`-from-tests-files limitation we hit during SUnit), runs each test method through SUnit, and emits one st-test row per Smalltalk method — 91 in total.
