refactor(type-inference): P3b — member.ts delegates to canonical + revert #521 workaround

[cs01]

Summary

Second consumer migration (plan P3b, after #525 P2).

• `MemberAccessGenerator.getObjectArrayElementInfo` now consults canonical `resolveExpressionTypeRich` first; legacy branches remain as fallback for shapes canonical doesn't yet enrich.
• With canonical covering indexed-object-array element-field access, PR fix(native): emitError chained method call caused segv on every compile error #521's `emitError` intermediate-variable workaround is reverted — the chained `method_call()[method_call().length - 1]` form now compiles correctly under the native compiler. Confirmed: `tests/fixtures/edge-cases/new-date-module-scope.ts` still prints the expected diagnostic instead of segfaulting.

Impact for users

Eliminates a whole chained-expression category of native-compiler segfaults that used to hide behind a mechanical workaround. The underlying type-propagation fix now lives in one place instead of being papered over at call sites.

Test plan

• `npm run verify` green (stage 2 self-hosting)
• `node --import tsx --test tests/self-hosting.test.ts` green (stage1 + stage2 fixture suite — the gap that bit us in refactor(type-resolver): P3a — delete dead resolveIndexedAccessType #526)
• Fuzz corpus /tmp/fuzz2/f*.ts: 12 pass, no regression
• `new-date-module-scope.ts` no longer relies on the fix(native): emitError chained method call caused segv on every compile error #521 workaround
