chore(release): 0.12.0 -- a session measures the effort it ran with

Bumps the six version-bearing files and gives ac62a38 its changelog entry.

Until the tag exists the plugin cache keeps serving the 0.11.0 skill, which
instructs every new session that effort is not observable and to ask the
operator for it. The fix is committed and pushed but not in circulation, so
the release is the part that changes behavior.
