refactor: rename oil to canola across entire codebase

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.

**Q: How do I migrate from `stevearc/oil.nvim`?**
Change the plugin source and replace `setup()` with `vim.g.oil` in `init`. The
configuration table is identical — only the entry point changes. For example,
with [lazy.nvim](https://github.com/folke/lazy.nvim):

`init` runs before the plugin loads; `config` runs after. oil.nvim reads
`vim.g.oil` at load time, so `init` is the correct hook. Do not use `config`,
`vim.g.canola` at load time, so `init` is the correct hook. Do not use `config`,
