fix(molecule): use Dependencies from bd show instead of empty DependsOn (#901)

* fix(molecule): use Dependencies from bd show instead of empty DependsOn

Bug: Molecule step dependency checking was broken because bd list
doesn't populate the DependsOn field (it's always empty). Only bd show
returns dependency info in the Dependencies field.

This caused all open steps to appear "ready" regardless of actual
dependencies - the polecat would start blocked steps prematurely.

Fix: Call ShowMultiple() after List() to fetch full issue details
including Dependencies, then check Dependencies instead of DependsOn.

Affected functions:
- findNextReadyStep() in molecule_step.go
- getMoleculeProgressInfo() in molecule_status.go
- runMoleculeCurrent() in molecule_status.go

Tests:
- Added TestFindNextReadyStepWithBdListBehavior to verify fix
- Added TestOldBuggyBehavior to demonstrate the bug
- Updated existing tests to use fixed algorithm

Also filter to only check "blocks" type dependencies - ignore "parent-child"
relationships which are just structural, not blocking.

- findNextReadyStep() in molecule_step.go
- getMoleculeProgressInfo() in molecule_status.go
- runMoleculeCurrent() in molecule_status.go
