* feat(preview): add `max_file_size` config to skip large file previews
Problem: previewing large files (e.g. 500 MB logs, binaries) loads them
into a buffer and can freeze or OOM Neovim. `disable_preview` only
receives the filename, so users cannot gate on file size.
Solution: add `preview_win.max_file_size` (number, MB, default 10). In
`open_preview`, check `entry.meta.stat.size` and fall back to
`vim.uv.fs_stat` when the cached stat is absent. If the file exceeds
the limit and a preview window is already open, render "File too large
to preview" in it; if not, emit a WARN notify and return early. The
cursor-moved auto-update path only fires when a window already exists,
so no flag threading is needed to distinguish explicit from implicit.

* feat(view): add `show_hidden_when_empty` for hidden-only directories
Problem: with `show_hidden = false`, a directory containing only
dotfiles renders as just `..`, giving no indication that entries exist.
Solution: add `view_options.show_hidden_when_empty` (boolean, default
false). After the main filter loop in `render_buffer`, if the option is
set and `#line_table <= 1`, iterate `entry_list` again and render any
entry not matched by `is_always_hidden`, using `is_hidden = true` so
they render with the dimmed hidden style.

* docs(upstream): fix formatting
* docs(upstream): update #213 and #473 with PR and commit links
Problem: users who want hands-off behaviour had no way to skip the
`prompt_save_on_select_new_entry` confirmation dialog — enabling the
prompt meant always being asked, with no silent auto-save path.
Solution: add `auto_save_on_select_new_entry` (default `false`) which,
when true, calls `M.save()` and proceeds immediately instead of showing
the confirm dialog. Includes type annotations, vimdoc, and upstream
tracker update for stevearc/oil.nvim#393.
* docs(upstream): triage batch — #739 cherry-pick, 10 issue updates
* feat: add `open_split` and `toggle_split` API
Problem: canola had no way to open a browser in a normal split window;
only floating windows were supported via `open_float`/`toggle_float`.
`M.close` also crashed with E444 when called from the last window.
Solution: port stevearc/oil.nvim#728 — add `open_split(dir, opts, cb)`
and `toggle_split(dir, opts, cb)` mirroring the float API. Use
`is_canola_win`/`canola_original_win` window vars (not the upstream
`is_oil_win` names). Wrap `nvim_win_close` in `pcall` with `enew()`
fallback to handle the last-window E444 case.

* fix: show float title when border is nil
Problem: the float title was only shown via the native `nvim_win_set_config`
path, which requires a border to render. The guard `config.float.border ~=
'none'` did not account for `nil`, which is the default — so users with no
explicit `border` config never saw the path title in the floating window.
Solution: require both `~= nil` and `~= 'none'` before using the native
title. In all other cases (border nil, 'none', or nvim < 0.9), fall back to
`util.add_title_to_win`, which renders a child floating window for the title.
Based on: stevearc/oil.nvim#683
* refactor: drop nvim-0.9 version checks in float title logic
Problem: when `prompt_save_on_select_new_entry` is enabled and the user
presses Escape on the "Save changes?" confirm dialog, `vim.fn.confirm`
returns 0, but the select continued as if the user had chosen "No".
Solution: add an explicit `choice == 0` branch that returns immediately,
aborting the select without saving or opening any files.
* fix: restore `buflisted` on jumplist buffer re-entry
Problem: Neovim's jumplist machinery re-enters canola buffers via an
internal `:edit`-equivalent path, which unconditionally sets
`buflisted = true`. The existing workaround in `open()` and
`open_float()` only covers canola-initiated navigation, leaving
`<C-o>` and `<C-i>` unhandled.
Solution: Apply the same `buf_options.buflisted` guard in the
`BufEnter` autocmd, directly after `set_win_options()`. This fires
on every buffer entry — including all jumplist paths — and mirrors
the pattern already used at the two `:edit` callsites.
* docs: mark upstream #302 as fixed in tracker
Problem: the codebase still used the upstream \`oil\` naming everywhere —
URL schemes, the \`:Oil\` command, highlight groups, user events, module
paths, filetypes, buffer/window variables, LuaCATS type annotations,
vimdoc help tags, syntax groups, and internal identifiers.
Solution: mechanical rename of every reference. URL schemes now use
\`canola://\` (plus \`canola-ssh://\`, \`canola-s3://\`, \`canola-sss://\`,
\`canola-trash://\`, \`canola-test://\`). The \`:Canola\` command replaces
\`:Oil\`. All highlight groups, user events, augroups, namespaces,
filetypes, require paths, type annotations, help tags, and identifiers
follow suit. The \`upstream\` remote to \`stevearc/oil.nvim\` has been
removed and the \`vim.g.oil\` deprecation shim dropped.
