* feat: emit \`CanolaFileCreated\` autocmd on file creation
Problem: no way to hook into individual file creation to populate
initial contents, without a plugin-specific config callback.
Solution: fire \`User CanolaFileCreated\` with \`data.path\` after each
successful \`fs.touch\` in the files adapter. Users listen with
\`nvim_create_autocmd\` and write to the path however they like.
* build: gitignore `doc/upstream.html`
* docs(upstream): mark #721 fixed, triage #735
* docs(upstream): simplify #735 note
