ci: run on Linux/macOS/Windows x Node 22/24

[isamu]

Summary

• Run CI across Linux × Windows × macOS on Node 22.x and 24.x (was Linux + Node 24 only)
• Reference: ../mulmoclaude/.github/workflows/pull_request.yaml — adopt the same matrix shape, Windows Defender disable, and Windows-specific node_modules cache pattern
• Preserve all existing typecheck / lint / build / test:* steps for this plugin
• Run npm pack + artifact upload only once (Linux + Node 24) to avoid 6-way artifact-name collisions

Items to Confirm / Review

• Matrix is node-version × os = 6 cells per run, fail-fast: false
• Windows uses windows-2022 (same as mulmoclaude reference). runner.os == 'Windows' branches disable the realtime AV scan and switch to an explicit actions/cache of node_modules (faster than setup-node's built-in yarn cache on NTFS)
• Timestamp step is wrapped in shell: bash so it runs on Windows too (PowerShell would choke on $(date +...))
• Pack/upload guard if: matrix.os == 'ubuntu-latest' && matrix.node-version == '24.x' keeps the artifact a single named npm-package

User Prompt

github actions, ../mulmoclaude を参考に、22/24と、mac/win/linux で動かすように全部変更して。

Notes

• dist/ not touched
• For plugins that previously had no workflow at all (TicTacToe, UiImage), this PR creates the initial pull_request.yaml
