Add rtkMethod so .Method( call sites rename with the method decl, improve
type renames across extend/annotations, and clip self to the enclosing
method body.
- Len→Length includes self.Len(); Point→Vec2 hits extend + types
- self→this stays within one method (textual func bounds)
- smoke_lsp_rename_method + test-lsp wiring
bux-lsp 0.7 indexes struct fields and enum variants and renames only the
right binding: .member / ::Variant / field-init, without clobbering locals.
- Member scan in analyzeFile; access kinds bare/dot/colon/field-init
- classifyRenameTarget: local | member | global
- smoke_lsp_rename_deep + test-lsp wiring
