Add Parse (AI brand visibility analytics)

[dapollonsky]

Adds Parse to two sections:

• Tools & Platforms: alongside its direct peers (Peec AI, Otterly, Profound, BrandRank). Parse tracks how brands appear in ChatGPT and Google AI Overviews, benchmarks against competitors, and surfaces fixes.
• Free Audits & Visibility Tools: Parse has a free brand lookup that returns an AI visibility read-out in under 30 seconds with no signup, consistent with the other free-tier entries listed there.

One-line entries, matched to the list format.
