fix(cli): add agents plan start alias or update spec to reflect v3 plan use/execute commands

Add 'start' as an alias for the existing 'use' command in the v3
plan lifecycle. Users familiar with previous naming conventions can
now use either 'agents plan start <action> <project>' or the primary
'agents plan use <action> <project>', both creating a plan in the
Strategize phase via the same underlying action service call.

+- **DoD Gating in Apply Phase** (#7927): `PlanLifecycleService.apply_plan` now
+  evaluates the plan's `definition_of_done` criteria before transitioning to the
+  Apply phase. If any required criteria fail, a `DoDGatingError` is raised and
+  the plan remains in Execute/COMPLETE state. The evaluation result is stored in
+  `plan.validation_summary` with `dod_evaluated=True` and `dod_all_passed`
+  reflecting the outcome. Plans with no DoD text skip evaluation and proceed
+  normally.
+
 ### Added
 - Wired `StrategyActor` into the real plan execution path: `_get_plan_executor`
   in `plan.py` now resolves the strategy actor via `resolve_strategy_actor()`

+Feature: Definition-of-Done Gating in Apply Phase
+  As a developer
+  I want the Apply phase to evaluate Definition-of-Done criteria
+  So that plans cannot be applied until all required DoD criteria pass
+
+  Background:
+    Given I have a plan lifecycle service for DoD gating
+
+  # --- DoD evaluation is skipped when no DoD text is set ---
+
+  Scenario: Apply succeeds when plan has no definition of done
+    Given I have a plan with no definition of done in execute complete state
+    When I apply the plan with DoD gating
+    Then the plan should transition to apply phase
+    And the plan validation summary should be empty
+
+  Scenario: Apply succeeds when definition of done is empty string
+    Given I have a plan with empty definition of done in execute complete state
+    When I apply the plan with DoD gating
+    Then the plan should transition to apply phase
+    And the plan validation summary should be empty
+
+  # --- DoD evaluation runs and passes ---
+
+  Scenario: Apply succeeds when all DoD criteria pass via context match
+    Given I have a plan with definition of done "tests_passed" and argument "tests_passed" equal to "true"
+    When I apply the plan with DoD gating
+    Then the plan should transition to apply phase
+    And the plan validation summary should record dod_evaluated as true
+    And the plan validation summary should record dod_all_passed as true
+
+  Scenario: Apply succeeds when DoD criteria are skipped due to empty context
+    Given I have a plan with definition of done "all tests pass" and no arguments
+    When I apply the plan with DoD gating
+    Then the plan should transition to apply phase
+    And the plan validation summary should record dod_evaluated as true
+
+  # --- DoD evaluation blocks apply when criteria fail ---
+
+  Scenario: Apply is blocked when DoD criteria fail
+    Given I have a plan with definition of done "coverage_above_97" and argument "status" equal to "incomplete"
+    When I try to apply the plan with DoD gating
+    Then a DoD gating error should be raised
+    And the plan should remain in execute phase
+    And the plan validation summary should record dod_evaluated as true
+    And the plan validation summary should record dod_all_passed as false
+
+  Scenario: DoDGatingError contains correct failure counts
+    Given I have a plan with definition of done "criterion_alpha" and argument "status" equal to "incomplete"
+    When I try to apply the plan with DoD gating
+    Then a DoD gating error should be raised
+    And the DoD gating error should report 1 failed criteria out of 1 total
+
+  # --- DoD evaluation with template rendering ---
+
+  Scenario: DoD template placeholders are rendered with plan arguments
+    Given I have a plan with definition of done "{status}" and argument "status" equal to "complete"
+    When I apply the plan with DoD gating
+    Then the plan should transition to apply phase
+
+  # --- validation_summary is populated ---
+
+  Scenario: validation_summary is populated after DoD evaluation
+    Given I have a plan with definition of done "tests_passed" and argument "tests_passed" equal to "true"
+    When I apply the plan with DoD gating
+    Then the plan validation summary should contain key "dod_evaluated" with value true
+    And the plan validation summary should contain key "dod_all_passed" with value true
+    And the plan validation summary should contain key "dod"
+
+  # --- DoD gating integrates with full lifecycle ---
+
+  Scenario: Plan with passing DoD can complete full apply lifecycle
+    Given I have a plan with definition of done "tests_passed" and argument "tests_passed" equal to "true"
+    When I apply the plan with DoD gating
+    And I start the apply phase
+    And I complete the apply phase
+    Then the dod plan processing state should be "applied"
+
+  Scenario: Plan with failing DoD stays in execute phase after blocked apply
+    Given I have a plan with definition of done "coverage_above_97" and argument "status" equal to "incomplete"
+    When I try to apply the plan with DoD gating
+    Then a DoD gating error should be raised
+    And the dod plan phase should be "execute"
+    And the dod plan processing state should be "complete"
