fix: make build and test suite pass on Windows

[noises1990]

What it does

Makes the project build and the full test suite pass on Windows without breaking macOS or Linux:

• Replaces the Unix-only package.json build script (cp ... 2>/dev/null || true, mkdir -p ...) with a cross-platform Node script (scripts/copy-assets.mjs).
• Fixes tests that assumed Unix-specific paths, HOME, and iii binary names:
  • test/cli-remove.test.ts — uses iii.exe on Windows, iii elsewhere.
  • test/compress-file.test.ts — uses path.resolve() and path.join() instead of literal /tmp/... paths.
  • test/copilot-plugin.test.ts — asserts resolveProject() result, not a hard-coded Windows absolute path.
  • test/obsidian-export.test.ts — uses os.tmpdir() + path.join() for export roots and file lookups.
  • test/slots-flag-gate.test.ts — sets/restores USERPROFILE alongside HOME because os.homedir() reads USERPROFILE on Windows.

Why

Windows contributors currently cannot run npm run build because the build pipeline relies on cp/mkdir shell tools that are not available in cmd.exe or PowerShell. Several unit tests also fail on Windows because they use /tmp/... literals, check for iii without the .exe extension, or only mock HOME while Node's os.homedir() prefers USERPROFILE on Windows. This PR removes those blockers.

How to verify

1. On a Windows machine, run npm install.
2. Run npm run build — it should complete without shell errors.
3. Run npm test — the full suite (excluding test/integration.test.ts) should pass.

The change is additive and should not affect Linux/macOS behavior: the shell pipeline is replaced by Node's fs/promises and path APIs, and the test fixes use standard cross-platform helpers.

Notes

• Does not address or introduce any source-code type errors. npx tsc --noEmit still reports the same pre-existing errors present on main.
• No linked issue — this was discovered while setting up a Windows development environment.

Summary by CodeRabbit

• Build

  • Improved distribution packaging by reliably copying viewer assets and optional configuration files during builds.

• Bug Fixes

  • Improved cross-platform handling for executable paths, project locations, temporary files, and home-directory resolution.
  • Corrected backup path and content handling for compressed files, including original Markdown files.

• Tests

  • Expanded platform-aware coverage for Windows and other operating systems.
  • Improved environment cleanup and path validation across export, plugin, and command-line tests.

📝 Walkthrough

Walkthrough

The build now delegates asset packaging to scripts/copy-assets.mjs. Tests now use platform-aware executable, file, temporary-directory, vault, backup, home-directory, and project paths.

Changes

Portable build and test paths

Layer / File(s)	Summary
Dedicated asset-copy build step package.json, scripts/copy-assets.mjs	The build runs tsdown, then creates dist/viewer and copies required viewer assets and optional root files.
Platform-aware file and executable fixtures test/cli-remove.test.ts, test/compress-file.test.ts, test/obsidian-export.test.ts	Tests now construct executable, fixture, backup, temporary, vault, and export paths with platform-aware helpers.
Windows environment and project resolution coverage test/slots-flag-gate.test.ts, test/copilot-plugin.test.ts	Tests isolate HOME and USERPROFILE, and derive the Copilot project from a Windows-style working directory.
