This commit introduces support for overriding the user_eq settings via a local user_eq.json file, allowing users to customize their audio profile without modifying the committed graph.json. The change includes:
- Adding user_eq.json to .gitignore
- Updating apply.sh to merge user_eq.json contents into the effective graph when present
- Rewriting INSTALL.md and README.md to document the new override workflow
- Enhancing preflight checks in apply.sh to use the merged graph
- Providing clear instructions for both override file and direct editing approaches
The new approach allows users to maintain custom EQ settings across git pulls while preserving the ability to edit graph.json directly when needed.
