refactor: Nuanced refinery context heuristic - 20 simple or immediate on complex (gt-nqrh)

Most MRs are button-pushes (clean rebase + push). Only complex rebases
(conflicts, test failures) consume significant context.

- 20 simple MRs before handoff
- Immediate handoff after any complex rebase

+**Heuristic**: Hand off after **20 simple MRs** OR **immediately** after any complex rebase.
+
+Most MRs are trivial:
+- Clean rebase (no conflicts)
+- Tests pass
+- Fast-forward merge + push
+
+These consume minimal context. But complex rebases are different:
+- Reading conflict diffs
+- Understanding competing changes
+- Manual resolution decisions
+- Re-running tests after fixes
+
+**Simple MR** (count toward 20):
+- `git rebase origin/main` succeeds without conflicts
+- Tests pass on first run
+
+**Complex MR** (triggers immediate handoff):
+- Rebase has conflicts requiring manual resolution
+- Tests fail and require investigation
+- Multiple rebase attempts needed
 
 **state.json format:**
 ```json
 {
-  "merges_processed": 0,
-  "last_patrol": "2025-12-23T13:30:00Z",
-  "conflict_resolutions": 0
+  "simple_merges": 0,
+  "complex_merge": false,
+  "last_patrol": "2025-12-23T13:30:00Z"

-## Context Management
-
-**Heuristic**: Hand off after processing **7 merge requests**.
-
-Merge requests are context-heavy:
-- Reading branch diffs
-- Resolving conflicts
-- Running tests
-- Composing notifications
-
 **At burn-or-loop step:**
-1. Read `state.json` for `merges_processed`
-2. If `merges_processed >= 7` → hand off
-3. Otherwise → continue patrol, spawn new wisp
+1. Read `state.json` for `simple_merges` and `complex_merge`
+2. If `complex_merge == true` → hand off immediately
+3. If `simple_merges >= 20` → hand off
+4. Otherwise → continue patrol, spawn new wisp
 
-**Rationale**: Merges consume significant context - each involves reading diffs,
-understanding changes, and sometimes resolving conflicts. A Refinery that has
-processed 7 MRs has filled substantial context.
+**Rationale**: A clean rebase is a button-push. A conflict resolution fills context
+with diffs, decisions, and debugging. Fresh context handles the next conflict better.
 
-**Handoff command:** `gt handoff -s "Patrol cycle" -m "Processed N merges"`
+**Handoff command:** `gt handoff -s "Patrol cycle" -m "Processed N simple merges"`
