Prepare aienvmap 0.2.2 release

[soovwv]

What changed

• ships the simplified two-tab Environment Overview and SBOM dashboard with independent rendering failure boundaries
• adds command-specific help, compact preflight output, environment/version evidence improvements, and focused module boundaries
• improves Windows atomic-write reliability and simplifies GitHub Action defaults
• updates market evidence, release metadata, changelog, tester guidance, and APM version references for 0.2.2
• extends the installed-package gate to generate and verify the simplified dashboard from the actual packed tarball

Why

The simplified dashboard and subsequent reliability/usability improvements were developed after npm 0.2.1 was published. Because npm versions are immutable, these changes require a new 0.2.2 release rather than reusing 0.2.1.

User impact

npx aienvmap@0.2.2 dash --open will show the concise environment overview and separate SBOM tab. Existing AI-readable JSON root fields remain frozen and additive from the 0.2.0 compatibility floor. The package remains dependency-free and advisory-only.
