feat: add WaitsFor parsing and mol bond command (gt-odfr, gt-isje)

WaitsFor parsing:
- Add WaitsFor []string field to MoleculeStep struct
- Parse WaitsFor lines in molecule descriptions
- Enables fanout gate semantics (e.g., WaitsFor: all-children)
- Case-insensitive parsing like Needs/Tier

mol bond command:
- Add gt mol bond for dynamic child molecule creation
- Supports --parent, --ref, and --var flags
- Enables Christmas Ornament pattern for parallel child execution
- Creates child issue with expanded template variables
- Instantiates proto steps under the bonded child

+This creates a new child molecule instance under the specified parent,

+spawn children for parallel execution.

+Examples:
+  # Bond a polecat inspection arm to current patrol wisp
+  gt mol bond mol-polecat-arm --parent=patrol-x7k --ref=arm-toast \
+    --var polecat_name=toast --var rig=gastown
+
+  # The child will have ID: patrol-x7k.arm-toast
+  # And template variables {{polecat_name}} and {{rig}} expanded
+
+Usage in mol-witness-patrol's survey-workers step:
+  for polecat in $(gt polecat list <rig> --names); do
+    gt mol bond mol-polecat-arm --parent=$PATROL_WISP_ID \
