Added

• cha analyze --top N flag — show only the N most severe findings (terminal format), complements --all
• Smell-level disable: disabled_smells = ["smell_name"] in .cha.toml (global) or under [languages.<lang>] (language-scoped). Finer-grained than disabling a whole plugin when it produces multiple smells
• Plugin::smells() — plugins declare which smell_name values they can produce. Exposed as a WIT export for WASM plugins
• cha plugin list now shows each plugin's declared smells
• cha preset show <lang> now shows effective disabled smells
• SDK helper cha_plugin_sdk::is_smell_disabled!(&input.options, "smell_name") — WASM plugins can skip disabled work proactively

Changed

• C/C++ builtin profile: builder_pattern, null_object_pattern, strategy_pattern, data_clumps are now properly disabled via smell-level config (previously tried — and failed — to disable them by plugin name)
• WIT analyzer world gains smells: func() -> list<string> export — breaking change for WASM plugins (recompile to pick up default impl)

Fixed

• lvgl-scale improvement: analyze now emits ~1200 fewer false positives because smell-level disables actually take effect
