ci: add CI workflow for tests, format check, and static analysis

[Copilot]

No CI workflow existed, so code changes were never automatically verified on PRs or pushes to master.

Changes

• .github/workflows/ci.yml — triggers on push/PR to master; runs dart pub get, dart format check, dart analyze --fatal-infos, and dart test
• Permissions — GITHUB_TOKEN scoped to contents: read (least privilege)

Uses only actions/checkout@v4 and dart-lang/setup-dart@v1; no new dependencies.

<issue_title>[Repo Assist] ci: add CI workflow for tests, format check, and static analysis</issue_title>
<issue_description>🤖 This PR was created by Repo Assist, an automated AI assistant for this repository.

The repository currently has no CI workflow that runs on pull requests or pushes to master. This means code changes are never automatically verified in CI.

This PR adds .github/workflows/ci.yml, a minimal CI workflow that runs on every push to master and every PR targeting master.

What it does

- dart pub get          # install dependencies
- dart format --output=none --set-exit-if-changed .  # check formatting
- dart analyze --fatal-infos   # static analysis
- dart test             # run test suite

These are exactly the same commands documented in .github/copilot-instructions.md and used for local development.

Rationale

• Prevents regressions: Automatically catches broken tests before merging.
• Enforces style: dart format check prevents unformatted code from entering the codebase.
• Zero new dependencies: Uses only dart-lang/setup-dart@v1 (official Dart team action) and actions/checkout@v4 (GitHub standard action).
• Minimal change: 18 lines added, no existing files modified.

Closes #71
Supersedes #73

Test Status

This PR only adds a workflow file — no Dart code changes. The workflow itself cannot be executed in the current sandbox environment, but its contents are identical to the commands documented in copilot-instructions.md and verified to work locally in this repo.

Subject: [PATCH] ci: add CI workflow to run tests, format check, and analysis
 on PRs

Adds .github/workflows/ci.yml that runs on every push/PR to master:
- dart pub get
- dart format check (fail if files not formatted)
- dart analyze --fatal-infos (static analysis)
- dart test (run test suite)

Ensures code quality is verified automatically on every contribution.
Fixes fredeil/email-validator.dart#71
