DSHX v0.7.0 — Harness Update Assistant

DSHX 0.7.0 adds a transactional DeepSeek Harness update workflow: plan, prepare an isolated candidate, verify plugin compatibility, apply with rollback evidence, and roll back when needed.\n\nIt also fixes lifecycle guidance: plugin work preserves the current Host PID by default. Client HMR/hot-mount and patch updates no longer trigger blanket Harness restart advice; restart is reserved for concrete boot-composition or unproven server-module changes.\n\nValidated locally with 110/110 tests, OKF v0.2 lint, npm pack dry-run, and real same-PID activation checks against the local Harness.
