Promote CHANGELOG Unreleased -> v2.8.0. Contents:
- Default models -> claude-sonnet-5 (changed-but-compatible; new containers only)
- opencode 1.17.15 -> 1.17.20
- bg-subagents removal-trigger markers refreshed 1.17.20/omos 2.2.0 (base-affecting
  -> base image rebuilds this release)
- README backfill for v2.4.0-v2.7.0 features + README/AGENTS polish

Minor per the repo versioning policy (tool bump paired with changed-compatible
default behaviour -> feature wins -> minor).

-## Unreleased
+## v2.8.0 — 2026-07-13
+
+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).
