docs: align all documentation with the new repo structure

Update agent protocols (.claude/agents, .github/agents), guides, runbooks and READMEs
to the post-restructure layout: .specify/{scripts,tests,security,config,templates,
governance,memory,level5-config} -> packages/casan-harness/...; docs/input +
golden-runs + traceability-map -> apps/okr/domain/...; drop AINative_OKR_CASAN5/ prefix.
Runtime-state paths (.specify/logs, .specify/agentops, .specify/level5/central-governance)
kept as-is. Historical evidence under docs/output/ left untouched (immutable run records).
