Fix dashboard plan-count zeroing + aipass bare-command introspection
Two verified bug fixes:
1. fix(flow): dashboard refresh no longer zeroes non-flow branch plan counts.
PLANS.central.json now comprehensive (all branches grouped per-branch).
Devpulse shows its 12 open plans again. +1 regression test, 734 pass.
2. fix(aipass): bare 'aipass <command>' runs instead of showing introspection
banner. All 7 modules fixed; 'aipass doctor' runs the health check.
Introspection moved to --info. seedgo standard bypassed for binary-invoked
modules. 424 tests pass.
Both verified independently: dashboard refresh writes active_plans=12 (was 0);
bare 'aipass doctor' runs the full check.
