Make compatible with Angular 20's new file naming convention

[tomwhite007]

Is your feature request related to a problem? Please describe. Angular 20 is introducing a new style guide and changes to the CLI to use simpler file naming conventions. The postfixes such as .component.ts and .service.ts are to become optional. This is a problem for the current Renamer extension process, which keys off the postfix to know what processes to run.

Describe the solution you'd like The Renamer process needs to become more generic so that the entry point can be in any .ts file, and the user can decide on naming conventions.
