feat(extraction): add CFML language support (.cfc/.cfm/.cfs) (#1118) (#1153)

Tag-based and bare-script CFML, extends/implements, <cfscript>/<cfquery> delegation, BOM + unquoted-attribute handling. Wasm grammars verified bit-for-bit reproducible from cfmleditor/tree-sitter-cfml. Validated on FW/1, ColdBox, CFWheels. Follow-up: #1152.
