feat: skip plan mode for fully-specified sequential tasks

Add Step 3 (Fully-Specified Task Detection) to the routing table in
delegate.md. When the user provides explicit ordered steps with no
ambiguities or design decisions, the orchestrator now routes to direct
sequential execution instead of entering plan mode unnecessarily.

Detection indicators:
- Numbered/ordered steps in the request
- Imperative sequential chains with concrete steps
- Explicit signals: "just do it", "no plan needed"
- All steps map trivially to tool calls
- Zero ambiguity markers

Closes #43

+### Step 3: Fully-Specified Task Detection
+
+**Pattern:** The user provided explicit, ordered steps with no ambiguities or design decisions needed. Every step is directly actionable without decomposition.
+
+**Indicators (ANY of these):**
+- Numbered or ordered steps in the request ("1. do X, 2. do Y, 3. do Z")
+- Imperative sequential chain ("do X, then Y, then Z" where each step is concrete)
+- Explicit skip-planning signals: "just do it", "no plan needed", "skip planning", "don't plan"
+- All steps map trivially to tool calls (edit file, run command, commit, push, merge, tag, release)
+- Zero ambiguity: no "should we", "which approach", "evaluate options", "design"
+
+**If fully-specified -> DIRECT SEQUENTIAL EXECUTION** (skip plan mode). Spawn one agent per step or batch related steps into a single agent. No `EnterPlanMode`, no `TaskCreate` during planning.
+
+### Step 4: Route Decision
 
 | Pattern | Route | Example |
 |---------|-------|---------|
 | Breadth + Write (same op x many items, with output) | **DIRECT EXECUTION** (skip plan mode) | "review 16 files, create reports" |
-| Multi-phase workflow (create -> test -> deploy) | plan mode (EnterPlanMode) | "create calculator with tests and verify" |
+| Fully-specified sequential task (all steps explicit) | **DIRECT SEQUENTIAL EXECUTION** (skip plan mode) | "bump version, commit, push, merge, tag, release" |
+| Multi-phase workflow (needs design/decomposition) | plan mode (EnterPlanMode) | "create calculator with tests and verify" |
 | Read-only breadth (no write indicators) | Spawn parallel Explore agents or codebase-context-analyzer | "explore code in X", "summarize files in X" |
 | Single simple task | general-purpose agent | "fix this bug" |
