Use same-file module variable initializers to filter builtin collection calls before class-name heuristics, and require a Python type node for the class escape. Preserve imported project module calls.
Add callers/callees regressions for dict, list, set, tuple, and frozenset, with a real instance control and same-name bindings across files.
Validation on Linux with Node 22.19.0: the new suite had 14 failures and one passing control on main at 8733c288; all 216 tests in the new suite, call-receiver-no-fabrication, and resolution now pass. TypeScript and copy-assets pass. Re-indexed /tmp/cg-1652-repro: callers get is empty and read_setting no longer calls a cache.py method.
