v0.1.0

First tagged release of pilestack.

Added

• Stack inference: a GitHub App that reads a repository's open PRs and groups
  them into stacks purely from each PR's base/head branch relationship — no
  bespoke integration with git-spice, git-town, or any other stacking CLI
  needed, since the base field is the same signal those tools already write.
• A stack view showing every PR in a stack, bottom to top, with live CI and
  review status.
• Cross-PR stack comments: a comment thread attached to the stack itself,
  visible from every PR in it — the one thing GitHub's own UI has no
  equivalent for.
• Restack: rebases and force-pushes (--force-with-lease) every open PR in a
  stack onto its correct base, with a mandatory diff preview and confirmation
  before anything is pushed. Stops at the first conflicting branch rather
  than leaving a partial, silently-broken push.
• GitHub OAuth sign-in; stack visibility is checked against the viewer's real
  GitHub repo permissions, not a separate Pilestack role.
• SQLite by default (zero extra infrastructure to self-host); a Dockerfile
  and docker-compose.yml for a one-command deploy.
• pnpm seed populates a realistic sample stack so the UI can be tried
  without connecting a real GitHub App first.

Fixed

• The Dockerfile failed to build for everyone, unconditionally: it copied a
  public/ directory that didn't exist in the repo. Added an (empty)
  public/ so docker compose up -d works as documented.
• pnpm db:deploy, pnpm db:migrate, and pnpm seed failed with
  Environment variable not found: DATABASE_URL even after following the
  README/CONTRIBUTING setup, because the Prisma CLI and tsx don't read
  .env.local the way Next.js does. Install docs now point at a plain
  .env file (which all three tools load), and pnpm seed passes
  --env-file=.env explicitly.
• pnpm build failed with Prisma type errors when following the README's
  "From source" steps, because a Prisma client had never been generated.
  Added the missing pnpm db:generate step.
• Added test coverage for src/lib/github-app.ts (installation token /
  Octokit App JWT wiring), the one previously-untested module in the stack;
  this also puts the nock dependency to use.

Built and self-hosted from source; see the README for the install path. Automated checks are not currently running on this repository, so this release is tagged from reviewed code rather than from a green CI run.
