Making rules with Lint
summary
Project adds a custom lint module packaged as an AAR, registers rules via an IssueRegistry, and implements a Detector that overrides getApplicableElements and visitElement to flag ImageView missing src (or enforcing app:srcCompat). Workflow uses a lint baseline to ignore ~existing warnings (about 400 built‑ins) and limits scope to resource files. Performance tips: use AGP 7.0 partial analysis, run a single target variant, avoid checkAllWarnings and test sources, and give lint more RAM — it reduces build time but still can be slow.
