* 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.
feat: add \`skip_confirm_for_delete\` option
Problem: there was no way to suppress the confirmation popup when the
only pending operations are deletes. \`skip_confirm_for_simple_edits\`
explicitly excludes deletes, so users who delete frequently had no opt-out.
Solution: add \`skip_confirm_for_delete = false\` config option. When true,
\`confirmation.show()\` skips the popup if every pending action is a delete.
Based on: stevearc/oil.nvim#392
Problem: When files are deleted via canola, any open Neovim buffers
for those files remain alive, polluting the jumplist with stale
entries.
Solution: Add an opt-in `cleanup_buffers_on_delete` config option
(default `false`). When enabled, `finish()` in `mutator/init.lua`
iterates completed delete actions and wipes matching buffers via
`nvim_buf_delete` before `CanolaActionsPost` fires. Only local
filesystem deletes are handled (guarded by the `files` adapter
check).
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.
