[TS] Evaluate instanceof against runtime constructor values

[CaelmBleidd]

Runtime constructor values now retain their project-class identity through locals, returned values and TypeScript assertions. instanceof evaluates the actual right-hand constructor and the left-hand object's declared ancestry; represented constructor values also return "function" from typeof.

Related to #457. This PR is stacked on #455 and requires the new IR from JacoDB #399. The repository's published JacoDB dependency pin is unchanged.

• Handle direct and conditional constructors, inherited checks, primitive and nullish left operands, and constructor-valued left operands against project classes.
• Produce a terminal JavaScript TypeError object for a known non-callable right operand.
• Report unknown constructor identity, computed static members that may implement Symbol.hasInstance, and constructor-valued entrypoint inputs as explicit unsupported outcomes. Inspect nested types and inherited fields conservatively; superclass generic specialization remains limited by JacoDB [TS PBT] Search bounded generator choices while preserving dependent input structure #400.
• Check ordinary supported source behavior with discoverProperties and invariants. Retain the direct machine API for unsupported outcomes, exception objects, stop reasons and generated Node replay cases.
• The concrete inherited-number input test checks only that the constructor-input guard allows the method. It does not establish witness reconstruction: TsTestResolver currently rejects an unresolved inherited field sort for that input.

Current head: bab79630bbf10cb08559ce1410cf69c1e3c2601e. Parent: #455 at e5527a3b67f476045aebea61a66bdc6e93c7b965. The production patch is unchanged by the test-style update and rebase.

Final combined stack at #466 acb1283d458d979a775dee8818d7ec5d1a29ba0f: 20 RuntimeInstanceofTest, 12 RuntimeNewTest and 6 TsStringEqualityTest cases passed, with no skips, failures or errors. :usvm-ts:detektTest and git diff --check passed. These local checks used the frozen JacoDB #399 commit b5e10a1a0c5d279492c373caf907f6387fff998f through -PuseLocalJacodb=/private/tmp/jacodb-ts-398-build.

Prototype mutation, unknown/function-object identities and custom Symbol.hasInstance remain outside the supported model. Catching the terminal TypeError inside the analyzed program requires the separate catch-routing change. CI with the older JacoDB artifact cannot validate the new IR dependency.
