docs: discover Rig/Cook/Run lifecycle - the three phases of work (gt-8tmz)

Key insight: Rig and Bond operate at different abstraction levels:
- Rig = source-level composition (formula YAML with extends/compose)
- Bond = artifact-level composition (protos, mols, wisps)

This preserves the symmetric bond table while cleanly separating
authoring (rig) from runtime composition (bond).

New docs:
- rig-cook-run.md: Canonical spec for the three phases

Updated docs:
- molecule-algebra.md: Three Phases section, rig/bond distinction
- molecular-chemistry.md: Rig/bond clarification in bond section
- vision.md: Core Innovation 3 now covers Rig/Cook/Run

"This is a discovery, not an invention."

+Work in Gas Town flows through three phases:

+```
+RIG ────→ COOK ────→ RUN
+```
+
+| Phase | What Happens | Key Operator |
+|-------|--------------|--------------|
+| **Rig** | Compose formulas (source level) | extends, compose |
+| **Cook** | Instantiate work (pour/wisp) | cook, pour, wisp |
+| **Run** | Execute steps | Agent execution |
+
+**Rig** is source-level composition (formula YAML).
+**Bond** is artifact-level composition (protos, mols, wisps).

 ### The Polymorphic Bond Operator
 
-**Bond** adapts to its operands:
-- Proto + Proto → Compound Proto (larger template)
-- Proto + Mol → Spawn and attach (template melts into flow)
-- Proto + Wisp → Spawn as vapor and attach
-- Mol + Mol → Link via dependencies
+**Bond** is the artifact-level combiner (distinct from **rig**, which composes
+source formulas). Bond adapts to its operands:
+
+| bond | Proto | Mol | Wisp |
+|------|-------|-----|------|
+| **Proto** | Compound Proto | Spawn + attach | Spawn wisp + attach |
+| **Mol** | Spawn + attach | Link | Link |
+| **Wisp** | Spawn + attach | Link | Link |
 
 This enables patterns like:
 - Patrol wisp discovers issue → bonds new work mol
