test(codemode): widen the test262 baseline to all implemented built-ins and expressions

[rekram1-node]

Follow-up to #48446. Manifest-only widening of the test262 baseline before the interpreter rewrite, so regressions anywhere in the object model are visible.

Changes

• manifest.json — directories now cover every built-in the interpreter implements (Array, Object, JSON, String, Number, Math, Boolean, Date, Map, Set, Promise, RegExp, Error/NativeErrors/AggregateError, the global functions and constants) plus language/expressions alongside language/statements. The boxed-primitive boundary also matches Object(<primitive>).
• skipped.txt — regenerated: 2093 known gaps with reasons.
• interpreter-support.md — new [ ] items for gap categories the wider run exposed: ToPrimitive on object operands, ToPropertyKey coercion, IteratorClose result validation, String.raw, string-method argument coercion, Date argument coercion; generator (not only async generator) parameter timing; propertyIsEnumerable.
• run.ts — names program functions in harness messages.

Results at the pinned revision

10311 files synced, 8218 pass, 2093 skipped, 0 fail; ~6 s for the full set. Files remain gitignored and are populated locally via script/sync-test262.ts; CI is unchanged.

Pass rate by area: Math 93%, Number 88%, Date 87%, JSON 86%, Set 86%, Promise 85%, statements 81%, Array 79%, expressions 79%, String 74%, RegExp 71%, Map 64%, Object 61%, Error 0% (all 15 use ToPrimitive on the message).

Largest gaps: function name/length (414), non-index array properties (277), interpreter errors typed Error instead of TypeError/RangeError/ReferenceError (152+), generator parameter evaluation timing (~200), const { constructor } = err (154), operators on non-data values (70).

[rekram1-node]

Keeping the widened baseline local until the rewrite; the test262 files don't run in CI, so this adds lines without changing what CI checks. The rewrite branches will base off test262-baseline and carry the skip-list changes their code causes.
