feat(transcend): carry session scripts, tests and skills into the repos

Adds kvb-transcend (collector), kvb-skills-transcend (into the skills repo) and kvb-code-transcend (into the current repo). transcend.py scans the own scratchpad, peer scratchpads and the agent homes for scripts, tests and skills the skills repo does not ship, skips secret-named and oversized files, and remembers carried/dropped decisions by content digest in the gitignored .state/transcend.json, so a rescan offers only new or changed candidates. Wired into kvb-skills-tune (own scripts), kvb-code-tune step 6 (measurements) and kvb-skills-dream step 7. Seven descriptions are tightened to stay inside the 1300-word listing budget.
