Update README.md files to match recent code changes

This is mostly adjustments to enum values so that the docs align correctly with the current code.

Also updated the calendar scope of the project to extend through March 2026.

 This directory contains the experimental builder feature for composable_kernel.
 
-* Status: In development (October - December 2025)
+* Status: In development (October 2025 - March 2026)
 
 ## Overview
 
 The builder provides a high-level, semantically-clear interface for constructing composable kernel operations, with an initial focus on convolution kernels for MIOpen. It leverages modern C++20 features (such as POD structs as non-type template parameters, concepts, and designated initializers) to simplify kernel instantiation and improve developer experience.
 
-This project is a prototype for a more general builder pattern for all of composable_kernel (CK) and CKTile, but is currently limited to formalizing the interface between MIOpen and CK.
