 Minor release. Headline: **default models move to `claude-sonnet-5`** and opencode bumps `1.17.15 → 1.17.20`. Rounds out with a large user-docs backfill — five v2.4.0–v2.7.0 base features (typst PDF export, terminal terminfo, Neovim 24-bit colour, the first-shell host SSH reachability check, the baked global gitignore) that had shipped without README prose — plus the bg-subagents removal-trigger "last-checked" markers refreshed to current versions. The marker refresh edits `Dockerfile.base`, so `base-<hash>` advances and the **base image rebuilds** this release (not just the variants).
