Delete the still-draft blog/2026-04-29-worktree-per-agent.md and move
blog/2026-04-28-byoh.md into blog/archive/ with archived: true and a
top-of-post note that the v1 framing differs. Add .claude/ICP.md with
primary persona, three JTBDs, top-3 needs, and an explicit anti-ICP
table (not multi-tenant SaaS, not non-developers, not production agent
operators, not comparison-shopping tinkerers). Strip the residual
"side-by-side" wording from docs/agents/overview.md so the grep gate
clears outside blog/archive/. Per SPEC v0.7 + the v07-convergence PRD.
