CONFLICT RESOLUTION *diffs-conflict*
diffs.nvim detects inline merge conflict markers (`<<<<<<<`/`=======`/
`>>>>>>>`) in working files and provides highlighting and resolution keymaps.
Both standard and diff3 (`|||||||`) formats are supported.
Conflict regions are detected automatically on `BufReadPost` and re-scanned
on `TextChanged`. When all conflicts in a buffer are resolved, highlighting
is removed and diagnostics are re-enabled.

{enabled} (boolean, default: true)
Enable conflict marker detection and

{disable_diagnostics} (boolean, default: true)
Suppress LSP diagnostics on buffers with
conflict markers. Markers produce syntax
errors that clutter the diagnostic list.
Diagnostics are re-enabled when all conflicts
are resolved. Set `false` to leave
diagnostics alone.
{show_virtual_text} (boolean, default: true)
Show virtual text labels (" current" and
" incoming") at the end of `<<<<<<<` and
`>>>>>>>` marker lines.
{keymaps} (table, default: see above)
Buffer-local keymaps for conflict resolution
and navigation. Each value accepts a string

HIGHLIGHT GROUPS *diffs-highlights*
diffs.nvim defines custom highlight groups. All groups use `default = true`,
so colorschemes can override them by defining the group before the plugin
loads.
All derived groups are computed by alpha-blending a source color into the
`Normal` background. Line-level groups blend at 40% alpha for a subtle tint;
character-level groups blend at 60% for more contrast. Line-number groups
combine both: background from the line-level blend, foreground from the
character-level blend.

`default = true`, so colorschemes can override them. Diff mode groups are
