Add Amazon Product Scout coworker: niche research, product development & competitor tracking

[Hdhaidong]

Summary

Adds Amazon Product Scout, a new built-in coworker for Amazon sellers and brand teams — market research, product development, and competitor tracking in one persona.

• Niche research from public signals (best-seller composition, review velocity, search-demand proxies, page-one competition) with an evidence-backed entry verdict
• Product development: competitor reviews mined into VOC clusters → a tiered product spec (must-fix / differentiators / nice-to-haves), with an estimates-labeled economics check and a risk sweep
• Competitor tracking as a standing watch: dated snapshots of tracked ASINs, delta briefs on each run, thesis-change escalation
• Listing teardown: title / bullets / imagery / A+ / pricing anatomy across the top listings, ending in the positioning gaps

Design notes

• Follows the existing persona bundle shape (manifest.md + skills/), like cloud-posture and security
• Uses only catalog capabilities (files, search, shell, todo) plus the browser connector — no API keys required; it works entirely from the web
• Marketplace access is strictly read-only by prompt: no purchases, no review actions, no bot-protection workarounds, modest request volume
• Evidence discipline: every observation carries its source URL + date; modeled numbers (margin, demand, landed cost) are labeled as estimates with assumptions stated
• Validated locally with the repo's own parse_manifest / PersonaRegistry loaders — the persona loads, surfaces in the picker, and its skill folders match the declared skills: list
