docs: restructure vimdoc with integrations parent section

Problem: integration docs (fugitive, neogit, gitsigns) were scattered
as top-level sections with no grouping, making it hard to find all
supported plugin integrations in one place.

Solution: add `|diffs-integrations|` parent section that groups all
integration subsections under a single TOC entry.

INTRODUCTION *diffs.nvim*
diffs.nvim adds syntax highlighting to diff views. It overlays language-aware
highlights on top of default diff highlighting in vim-fugitive, Neogit, and
Neovim's built-in diff mode.
diffs.nvim adds language-aware syntax highlighting to unified diff content
in Neovim buffers. It replaces flat `diffAdded`/`diffRemoved` coloring with
treesitter syntax, blended line backgrounds, and character-level intra-line
diffs.
With no configuration, diffs.nvim provides:
- `gitcommit` diff highlighting (e.g., `git commit --verbose`)
- Inline merge conflict detection, highlighting, and resolution
- Background-only diff colors for `&diff` buffers (vimdiff, diffthis)
All other integrations are opt-in. See |diffs-integrations|.
Features: ~
- Syntax highlighting in |:Git| summary diffs and commit detail views
- Diff header highlighting (`diff --git`, `index`, `---`, `+++`)
- Syntax highlighting in |:Gdiffsplit| / |:Gvdiffsplit| side-by-side diffs
- |:Gdiff| command for unified diff against any git revision
- gitsigns.nvim blame popup highlighting (see |diffs-gitsigns|)
- Background-only diff colors for any `&diff` buffer (vimdiff, diffthis, etc.)
- Treesitter syntax highlighting in diff hunks
- Character-level intra-line diff highlighting
- Vim syntax fallback for languages without a treesitter parser
- Blended diff background colors that preserve syntax visibility
- Optional diff prefix (`+`/`-`/` `) concealment
- Gutter (line number) highlighting
- Inline merge conflict marker detection, highlighting, and resolution
- |:Gdiff| unified diff against any revision
- Email quoting/patch syntax support (`> diff ...`)

REQUIREMENTS *diffs-requirements*
- Neovim 0.9.0+
- vim-fugitive (https://github.com/tpope/vim-fugitive) (optional, for unified
diff syntax highlighting in |:Git| and commit views)
- Treesitter parsers for languages you want highlighted
Note: The diff mode feature (background-only colors for |:diffthis|, vimdiff,
etc.) works without vim-fugitive.
==============================================================================
SETUP *diffs-setup*
Install with lazy.nvim: >lua
{
'barrettruth/diffs.nvim',
dependencies = { 'tpope/vim-fugitive' },
}
{ 'barrettruth/diffs.nvim' }
<
The plugin works automatically with no configuration required. For
customization, see |diffs-config|.
NOTE: Load your colorscheme before `diffs.nvim`. For example, with lazy.nvim,
set `priority = 1000` and `lazy = false` on your colorscheme plugin.
Do not lazy load with `event`, `lazy`, `ft`, `config`, or `keys` —
diffs.nvim lazy-loads itself.
NOTE: Load your colorscheme before diffs.nvim. With lazy.nvim, set
`priority = 1000` and `lazy = false` on your colorscheme plugin.
See |diffs-config| for customization, |diffs-integrations| for plugin
support.

FUGITIVE STATUS KEYMAPS *diffs-fugitive*
INTEGRATIONS *diffs-integrations*
When inside a vim-fugitive |:Git| status buffer, diffs.nvim provides keymaps
to open unified diffs for files or entire sections.
diffs.nvim integrates with several plugins. There are two attachment
patterns:
Automatic: ~
Enable via config toggles. The plugin registers `FileType` autocmds for
each integration's filetypes and attaches automatically.
>lua
vim.g.diffs = {
fugitive = true,
neogit = true,
gitsigns = true,
}
<
Opt-in: ~
For filetypes not covered by a built-in integration, use `extra_filetypes`
to attach to any buffer whose content looks like a diff.
>lua
vim.g.diffs = { extra_filetypes = { 'diff' } }

vim.g.diffs = { neogit = true }

Expanding a diff in a Neogit buffer (e.g., TAB on a file in the status
view) applies treesitter syntax highlighting and intra-line diffs to the
hunk lines.

vim.g.diffs = { gitsigns = true }
<
`:Gitsigns blame_line full=true` popups receive treesitter syntax, line
backgrounds, and intra-line diffs.
Highlights are applied in a separate `diffs-gitsigns` namespace and do not
interfere with the main decoration provider used for diff buffers.

CONFLICT RESOLUTION *diffs-conflict*
@ -642,52 +703,6 @@ The working file buffer is modified in place; save it when ready.
Phase 1 inline conflict highlights (see |diffs-conflict|) are refreshed
automatically after each resolution.
==============================================================================
NEOGIT *diffs-neogit*
diffs.nvim works with Neogit (https://github.com/NeogitOrg/neogit) out of
the box. Enable Neogit support in your config: >lua
vim.g.diffs = { neogit = true }
<
When a diff is expanded in a Neogit buffer (e.g., via TAB on a file in the
status view), diffs.nvim applies treesitter syntax highlighting and
intra-line diffs to the hunk lines, just as it does for fugitive.
Neogit highlight overrides: ~
On first attach to a Neogit buffer, diffs.nvim overrides Neogit's diff
highlight groups (`NeogitDiffAdd*`, `NeogitDiffDelete*`,
`NeogitDiffContext*`, `NeogitHunkHeader*`, `NeogitDiffHeader*`, etc.) by
setting them to empty (`{}`). This gives diffs.nvim sole control of diff
line visuals. The overrides are reapplied on `ColorScheme` since Neogit
re-defines its groups then. When `neogit = false`, no highlight overrides
are applied.
==============================================================================
GITSIGNS *diffs-gitsigns*
diffs.nvim can enhance gitsigns.nvim blame popups with syntax highlighting.
Enable gitsigns support in your config: >lua
vim.g.diffs = { gitsigns = true }
<
When `:Gitsigns blame_line full=true` opens a popup, diffs.nvim intercepts
the popup and replaces gitsigns' flat `GitSignsAddPreview`/
`GitSignsDeletePreview` highlights with:
- Treesitter syntax highlighting on the code content
- `DiffsAdd`/`DiffsDelete` line backgrounds
- Character-level intra-line diffs (`DiffsAddText`/`DiffsDeleteText`)
- `@diff.plus`/`@diff.minus` coloring on `+`/`-` prefix characters
The integration patches `gitsigns.popup.create` and `gitsigns.popup.update`
so highlights persist across gitsigns' two-phase render (initial popup, then
update with GitHub/PR data). If gitsigns loads after diffs.nvim, a
`User GitAttach` autocmd retries the setup automatically.
Highlights are applied in a separate `diffs-gitsigns` namespace and do not
interfere with the main decoration provider used for diff buffers.
