docs: align Transparency Note with AI Messaging Guidance

[raymond-nassar]

Description

Ports the approved PR #2020 Transparency Note update to main. PR #2020 merged into docs/transparency-note, so the approved file changes did not reach the default branch.

Aligns the HVE Core Transparency Note with the AI Messaging Guidance. Four prose edits:

• adds a limitation that outputs inherit the host model's properties (can fail, not neutral, not bias-free)
• describes agents and prompts by capability instead of productivity claims
• enumerates Microsoft's six AI principles
• softens "the right" to "appropriate" Responsible AI controls

File scope: TRANSPARENCY-NOTE.md only.

Type of Change

Code & Documentation:

• Documentation update

Testing

Targeted local validation on TRANSPARENCY-NOTE.md:

• npx markdownlint-cli2 TRANSPARENCY-NOTE.md: pass
• npx cspell TRANSPARENCY-NOTE.md: pass, 0 issues
• git diff --check origin/main..HEAD: pass
• & .\scripts\linting\Markdown-Link-Check.ps1 -Path @('TRANSPARENCY-NOTE.md'): passed once before push; later reruns returned HTTP 403 from Microsoft pages (https://www.microsoft.com/ai/responsible-ai and https://www.microsoft.com/ai/tools-practices). The file diff remains unchanged because it intentionally mirrors the approved PR docs: align Transparency Note with AI Messaging Guidance #2020 patch.
