ci: add scoop and winget release workflows

[setoelkahfi]

Summary

Add Scoop and Winget package manager release workflows, completing the distribution channel coverage alongside Homebrew, npm, PyPI, NuGet, pub.dev, and crates.io.

Changes

• .github/workflows/release-github.yml — Added a checksum step that generates .sha256 sidecars for all release assets, and a dispatch step that triggers release-scoop.yml and release-winget.yml with per-workflow error isolation.
• .github/workflows/release-scoop.yml (new) — Downloads .sha256 sidecars from the release, checks out ondeinference/scoop-bucket, generates bucket/onde.json manifest, validates JSON, commits and pushes.
• .github/workflows/release-winget.yml (new) — Branches: if the package exists in microsoft/winget-pkgs → wingetcreate update; if not → render templates from packaging/winget/*.yaml.in and wingetcreate submit. Runs on windows-latest.
• packaging/winget/*.yaml.in (new) — Winget manifest templates (version, locale, installer) with @PLACEHOLDER@ substitution via sed. Package identifier: OndeInference.onde-cli.
• .gitignore — Added .playwright-mcp/.

Required secrets (set on ondeinference/onde-cli)

• SCOOP_BUCKET_TOKEN — PAT with push access to ondeinference/scoop-bucket
• WINGET_TOKEN — PAT with public_repo scope (wingetcreate forks microsoft/winget-pkgs and opens a PR)

Binary names consumed

• onde-win-amd64.exe + .sha256 (scoop + winget x64)
• onde-win-arm64.exe + .sha256 (winget arm64)

This change adds Scoop and Winget release workflows to the CI, enabling automated publishing to these Windows package managers alongside existing channels. The main workflow now generates .sha256 checksum sidecars for all release assets and triggers the new workflows for Scoop and Winget, each with error isolation. The Scoop workflow downloads checksums, updates the ondeinference/scoop-bucket repo with a new manifest, and validates the JSON before committing. The Winget workflow checks if the package exists in microsoft/winget-pkgs and either updates it or submits a new manifest, rendering templates from packaging/winget/*.yaml.in. The .gitignore is updated for Playwright MCP artifacts. The server.json metadata is expanded with more descriptive title, description, categories, and keywords. No earlier findings are present to address.
