Follow-up to #539, as requested in #521. Feasibility spike only.
It parses a typed TypeScript fixture with an ANTLR grammar, converts the tree into the engine's blocks, scopes and calls, and runs one rule (crypto.createHash with dependent update and digest) through the shared DetectionEngine and DetectionStore to a CBOM digest node. The test covers the sequential form, the inline chain, and a case where an unrelated logger.update must not attach.
About 1,300 of the lines are the vendored antlr/grammars-v4 TypeScript grammar (MIT). Nothing is registered in the plugin yet and there is no sensor.
The evaluation, known gaps and open questions are in my comment on #521: #521 (comment)
