ahoy reports no gaps while abcd lint errors on the missing shared work tier

After a v0.12.0 to v0.13.1 install, both ahoy and ahoy doctor report zero gaps. abcd lint in the same checkout exits 2: rule three-tier-layout errors that the shared working tier (the work folder under the abcd directory) is missing, and decision-durability warns that no committed DECISIONS.md exists there. The install that declares the repository fully set up never creates the tier its own lint requires, so a freshly adopted repository fails lint with nothing on the setup side pointing at it.

To see it: adopt a repository with ahoy install, confirm ahoy reports no gaps, run abcd lint.

Remedy the reporter proposes: Have ahoy detect the missing shared work tier as a safe-autocreate gap and create it on install, or relax the lint rule for repositories ahoy considers healthy.
