Current Behavior

@nx/js/typescript follows extends only for the tsconfig a target is inferred from, not for that tsconfig's internal project references. In this common layout:

// libs/my-lib/tsconfig.json
{ "files": [], "references": [{ "path": "./tsconfig.lib.json" }, { "path": "./tsconfig.spec.json" }] }

// libs/my-lib/tsconfig.lib.json
{ "extends": ["./tsconfig.json", "../../tsconfig.lib.base.json"] }

tsconfig.lib.base.json is not a typecheck input, so editing it affects no projects and keeps stale cache hits. It is also missing from the createNodes cache key, so inferred targets don't update when it changes (e.g. its ${configDir} include).

Expected Behavior

Configs extended by internal project references, recursively, are typecheck and build inputs and part of the createNodes cache key. Duplicate config inputs are dropped, since references usually extend ./tsconfig.json.

Related Issue(s)

None filed. #35457 fixed this for external references only. It skips workspace-root files, assuming the project's own extends walk covers them, which isn't true for internal references.
