Harden knowledge writes and validate the packed CLI across thirty repositories

[liolevx]

Summary

• Enforce aggregate owned-knowledge write limits, safe learning destinations, and correct nested index links.
• Recognize ignored root agent instructions and distinguish API documentation from task-routing guidance.
• Replace the README workflow diagram with the supplied illustrative terminal image; shorten the README by 78 words.
• Retain pinned thirty-repository acceptance results and reproducible native-test runners.

Validation

• Complete Windows check: 178 tests passed, including build and packed CLI installation smoke.
• Complete clean Linux check: 176 passed, two Windows-specific cases skipped; package smoke passed.
• npm dependency audit: zero reported vulnerabilities.
• Thirty-repository breadth run: 29 repeatable initializations, one conservative refusal; 27 lifecycle safety cases exercised.
• ItsDangerous: 298 native tests passed through finish. Kleur: existing Node 24 test-loader failure correctly reported as failed.

Remaining release gates

Real signed-in coding-agent invocation and independent fresh review remain unverified. This PR does not claim thirty autonomous feature implementations. npm publication is not part of this merge.
