feat: make Direct evidence trace inspectable

[0thernet]

Summary

Reframes Direct around one inspectable browser trace before reference depth.

• shows the exact URL-to-claim evidence chain and compact live Todo trace
• clarifies the Skill, TypeScript package, and browser-driver interfaces
• carries the evidence-led article into the canonical website surface
• prepares the immutable v0.7.16 package/release references
• adds README structure and release-alignment contracts

Validation

• bun run typecheck
• bun run build
• focused npm release workflow contracts: 10 pass, 300 assertions
• README audit: 32 balanced fences, 12 local links resolved, 28 headings
• git diff --check
• package smoke reached exact 59-file archive installation and current-package Node import; sandbox registry access blocked only verification dependency downloads, so required CI owns the complete package/aggregate gate.
