Chinesezjc 345375747e perf(tools): cap propagated class names so deep oneOf-object chains stay linear
The oneOf perf fix left a second Θ(depth²): a deep oneOf chain whose branches
are named objects propagated an ever-growing ConsString as the class-name
base, which allocateClassName then re-materialized (.length/.slice) at every
level. A childClassName helper now caps the base AT PROPAGATION, so each level
is O(1) and the walk is linear; the collision counter still makes truncated
bases unique. Also reword the oneOf comment (it said `+` but the code uses a
template literal — both are ConsString) and strengthen the tests: the deep
oneOf test now runs 100k levels (a quadratic regression trips the 5s timeout),
plus a 60k oneOf-object chain and a >120-char tool-name cap case. py-types.ts
stays at 100% per-file coverage.
