Docs/issue 133 vision readme

[rosspeili]

Description

Docs-only PR for #133: adds docs/vision.md as the canonical project story and lightly reshapes README navigation and contributor-facing copy. Also includes README, conduct, and cross-link polish discovered while implementing the issue.

New

• docs/vision.md — origin story, why not prompts-only, wallet screening narrative, agent discoverability, v0–v3 roadmap (with examples), current state, contributor invite
• Wallet screening comparison table in COMPARISON.md (not README — keeps Comparison scannable)

README

• Mission links to Vision; expanded Logic / Cognition / Governance / Interface list
• Top nav + grouped Documentation table (Introduction · Usage guides · Contributing)
• Skill library site link opens in new tab (↗)
• Contributing section as short paragraphs (points to docs table; no duplicate bullet farm)
• Contact: enterprise (skills@), security (security@ + SECURITY.md), skill-author note (card, library, site)

Cross-links

• docs/introduction.md, CONTRIBUTING.md, docs/contributing/ai_native_workflow.md, COMPARISON.md → vision.md

Beyond #133 scope (included in same PR)

• CODE_OF_CONDUCT.md — under Contribution process: skill issuer requirements + disclaimer/promo review expectations
