Build fails due to .gitignore pattern excluding direnv.nix

[popey]

Description

The build process fails with a "path does not exist" error for because the pattern incorrectly excludes this required file from version control.

Steps to Reproduce

1. Clone the noughtylinux/config repository
2. Set up the required configuration files (config.toml with system/user sections)
3. Run just build

Expected Behavior

The build should complete successfully, building both system-manager and home-manager configurations.

Actual Behavior

The build fails with:

error: path '/nix/store/...-source/home-manager/terminal/direnv.nix' does not exist

This occurs because:

• The file exists in the working directory
• home-manager/terminal/default.nix imports ./direnv.nix
• The .gitignore pattern .direnv* prevents Git from tracking the file
• Nix flakes only include Git-tracked files in the store

Error Messages

error:
       … while evaluating a branch condition
         at /nix/store/.../lib/lists.nix:142:18:
          141|       len = length list;
          142|       fold' = n: if n == len then nul else op (elemAt list n) (fold' (n + 1));

       error: path '/nix/store/.../home-manager/terminal/direnv.nix' does not exist

Workaround

Run git add -f home-manager/terminal/direnv.nix to force-add the file despite the gitignore pattern.

Proposed Fix

Update .gitignore to be more specific, e.g.:

.direnv/
.envrc

Instead of the overly broad:

.direnv*

This would exclude direnv's working directory and environment files while preserving the required direnv.nix configuration file.
