build: add nix devshell and pre-commit hooks

Problem: oil.nvim had no reproducible dev environment. The .envrc
set up a Python venv for the now-removed docgen pipeline, and there
were no pre-commit hooks for local formatting checks.

Solution: add flake.nix with stylua, selene, and prettier in the
devshell. Replace the stale Python .envrc with 'use flake'. Add
.pre-commit-config.yaml with stylua and prettier hooks matching
other plugins in the repo collection.

+**Q: How do I migrate from `stevearc/oil.nvim` to `barrettruth/oil.nvim`?**
 
-Change the plugin source and replace `setup()` with `vim.g.canola` in `init`.
-The configuration table is identical — only the entry point changes. For
-example, with [lazy.nvim](https://github.com/folke/lazy.nvim):
-
-Before (`stevearc/oil.nvim`):
+Replace your `setup()` call with a `vim.g.oil` assignment. For example, with
+[lazy.nvim](https://github.com/folke/lazy.nvim):
 
 ```lua
+-- before
 {
   'stevearc/oil.nvim',
-  opts = { ... },
   config = function(_, opts)
     require('oil').setup(opts)
   end,
+  opts = {
+    ...
+  }
 }
-```
 
-After (`barrettruth/canola.nvim`):
-
-```lua
+-- after
 {
-  'barrettruth/canola.nvim',
-  opts = { ... },
-  config = function(_, opts)
-    require('canola').setup(opts)
+  'barrettruth/oil.nvim',
+  init = function()
+    vim.g.oil = {
+      columns = { "icon", "size" },
+      delete_to_trash = true,
+    }
   end,
 }
 ```
 
-`init` runs before the plugin loads; `config` runs after. oil.nvim reads
-`vim.g.canola` at load time, so `init` is the correct hook. Do not use `config`,
-`opts`, or `lazy` — oil.nvim loads itself when you open a directory.

-**Q: Why "canola"?**
-
-Canola oil! But...
-
 **Q: Why "oil"?**
 
-From the [vim-vinegar](https://github.com/tpope/vim-vinegar) README, a quote by
-Drew Neil:
+**A:** From the [vim-vinegar](https://github.com/tpope/vim-vinegar) README, a quote by Drew Neil:
 
 > Split windows and the project drawer go together like oil and vinegar
 
+Vinegar was taken. Let's be oil.
+Plus, I think it's pretty slick ;)
+
+**Q: Why would I want to use oil vs any other plugin?**
+
+**A:**
+
+- You like to use a netrw-like view to browse directories (as opposed to a file tree)
+- AND you want to be able to edit your filesystem like a buffer
+- AND you want to perform cross-directory actions. AFAIK there is no other plugin that does this. (update: [mini.files](https://github.com/nvim-mini/mini.nvim/blob/main/readmes/mini-files.md) also offers this functionality)
+
+If you don't need those features specifically, check out the alternatives listed below
+
+**Q: Can oil display files as a tree view?**
+
+**A:** No. A tree view would require a completely different methodology, necessitating a complete rewrite.
+
 **Q: What are some alternatives?**
