Ignore CLAUDE.local.md and AGENTS.local.md during project render and template use

The .local.md variants of AI assistant config files were not excluded from
project file discovery or extension templates. Extends the ignore patterns
added in #13907 to also cover these files.

Fixes #14198

 - ([#13856](https://github.com/quarto-dev/quarto-cli/issues/13856)): Add code annotation support for Typst and Observable.js code blocks. (author: @mcanouil)
 - ([#13890](https://github.com/quarto-dev/quarto-cli/issues/13890)): Fix render failure when using `embed-resources: true` with input path through a symlinked directory. The cleanup now resolves symlinks before comparing paths.
 - ([#13907](https://github.com/quarto-dev/quarto-cli/issues/13907)): Ignore AI assistant configuration files (`CLAUDE.md`, `AGENTS.md`) when scanning for project input files and in extension templates, similar to how `README.md` is handled.
+- ([#14198](https://github.com/quarto-dev/quarto-cli/issues/14198)): Ignore `.local.md` variants of AI assistant configuration files (`CLAUDE.local.md`, `AGENTS.local.md`) during project render and `quarto use template`.
 - ([#13935](https://github.com/quarto-dev/quarto-cli/issues/13935)): Fix `quarto install`, `quarto update`, and `quarto uninstall` interactive tool selection.
 - ([#13992](https://github.com/quarto-dev/quarto-cli/issues/13992)): Fix crash when rendering div with both cross-reference ID and conditional visibility to PDF.
 - ([#13997](https://github.com/quarto-dev/quarto-cli/issues/13997)): Fix Windows dart-sass theme compilation failing when Quarto is installed in a path with spaces (e.g., `C:\Program Files\`) and the project path also contains spaces.
