feat: use autofix.ci to auto-update dist/ on all PRs (#308)

## Summary

Switches from our custom GitHub Actions workflow to
[autofix.ci](https://autofix.ci/) for automatically updating the `dist/`
folder. This solves the CI triggering issue and works on all PRs, not
just Renovate PRs.

## Problem Solved

The previous workflow had a critical issue: commits made with
`GITHUB_TOKEN` don't trigger other CI workflows (by design to prevent
infinite loops). This meant that after the dist/ folder was updated, CI
wouldn't run to verify the changes.

## Solution: autofix.ci

autofix.ci uses a GitHub App token to make commits, which **does**
trigger CI workflows. This ensures that:
- ✅ CI tests run after dist/ is updated
- ✅ Works on ALL PRs, not just Renovate
- ✅ Renovate still recognizes and can rebase PRs (via
`gitIgnoredAuthors`)

## Changes

- **Renamed workflow**: `renovate-dist-update.yml` → `autofix.yml`
- **Removed filters**: Now runs on all PRs (not just when specific files
change)
- **Removed Renovate check**: Works for all PR authors, not just
renovate[bot]
- **Switched to autofix.ci**: Replaced manual commit logic with
autofix.ci action
- **Updated permissions**: Changed from `write` to `read` (autofix.ci
handles commits)
- **Updated renovate.json**: Added `autofix.ci[bot]` to
`gitIgnoredAuthors`

## Setup Required

This PR requires installing the autofix.ci GitHub App:
👉 https://github.com/apps/autofix-ci

## Testing

Once the app is installed, this workflow will automatically:
1. Run on every PR
2. Execute `npm run all` to rebuild dist/
3. Let autofix.ci commit any changes
4. Trigger CI workflows to verify the changes

> [!NOTE]
> Replaces the Renovate-only dist update workflow with an
autofix.ci-based workflow that runs on all PRs and main pushes, and
updates Renovate to ignore autofix.ci commits.
> 
> - **CI**:
> - Add `/.github/workflows/autofix.yml` to build (`npm run all`) and
let `autofix.ci` commit fixes on PRs and `main` pushes.
> - Remove `/.github/workflows/renovate-dist-update.yml` and its manual
commit/push logic.
> - **Renovate**:
> - Update `/.github/renovate.json` to set `gitIgnoredAuthors` to
`autofix.ci[bot] <autofix.ci[bot]@users.noreply.github.com>`.
