[TS] Construct project instances from runtime constructor values

[CaelmBleidd]

Dynamic new now consumes JacoDB's evaluated constructor value, resolves its exact project-class identity and allocates that class before executing the existing constructor call. Conditional constructors, returned constructor values, local aliases and argument side effects preserve the selected identity.

Closes #465. This PR is stacked on #464 and requires JacoDB #399; the repository's published JacoDB pin is unchanged.

• Preserve direct construction and execute the selected constructor exactly once.
• Read and write common-name fields using the allocated object's runtime class and value sort.
• Produce terminal TypeError objects for known non-constructable primitives and ordinary project-class instances; report unresolved constructor identity as unsupported.
• Report field writes that change the selected field's runtime sort as unsupported, including incompatible alternatives of a number|string value. [TS] Support field assignments that change the runtime value sort #467 tracks full support.
• Check ordinary source behavior through discoverProperties, including both constructor choices and result invariants. The identical-result field-read scenario uses withOptions to collect all states instead of stopping after 100% coverage. Keep the direct API for unsupported outcomes, exception details, stop reasons and generated Node replay cases.

Current head: acb1283d458d979a775dee8818d7ec5d1a29ba0f. Parent: #464 at bab79630bbf10cb08559ce1410cf69c1e3c2601e. The production patch is unchanged by the test-style update and rebase.

On this final head, 12 RuntimeNewTest, 20 parent RuntimeInstanceofTest and 6 TsStringEqualityTest cases passed: 38 tests, zero skips, failures or errors. :usvm-ts:detektTest and git diff --check also passed. Tests include Node replay and used a local composite build against the frozen JacoDB #399 commit b5e10a1a0c5d279492c373caf907f6387fff998f via -PuseLocalJacodb=/private/tmp/jacodb-ts-398-build.

Published CI using an older JacoDB artifact cannot validate the new constructor IR operand. Merge after #464 and the corresponding JacoDB dependency update.
