Bundled the release history as a fallback when package assets cannot be resolved, while preserving external package-directory overrides.
Added regression coverage for the compiled-binary fallback.
Fixes#6172
- Preserved newest-first ordering for startup changelog markdown so collapsed notices report the current release.
- Kept default changelog rendering oldest-first for explicit recent/full views.
- Added regression assertions for both startup and full-history heading order.
- Treated missing or invalid changelog markers as first install and persisted the current version without replaying historical notes.
- Shared bounded changelog rendering between startup and recent changelog views, with a 64 KiB startup cap and full-history hint on truncation.
- Added marker, truncation, recent/full rendering, and PTY startup regression coverage.
Fixes#5135
