chore(release): v0.5.0

Manual version bump to 0.5.0 (changeset version produced 1.0.0 from a
single minor changeset against 0.4.1; that release was rolled back and
the 1.0.0 npm version deprecated).

Aggregates: status terminology refresh (planning/replan), Reviewer
rename, in-review pause behavior, dashboard-tui resize hardening,
dev-server experimental toggle fix, version reporting fix.
