feat(db): rebaseline plan phase/state enums for Action and Apply terminal states

+"""Rebaseline plan phase/state enums for Action + Apply terminal states.
+
+This migration updates the ``v3_plans`` table CHECK constraints to align with
+the four-phase lifecycle: Action -> Strategize -> Execute -> Apply.
+
+Changes:
+- ``ck_v3_plans_phase``: add ``'action'``, remove ``'applied'``
+- ``ck_v3_plans_state``: add ``'applied'`` and ``'constrained'``
+- Default ``phase`` changes from ``'strategize'`` to ``'action'``
+
+SQLite does not support ``ALTER TABLE ... DROP CONSTRAINT``, so we rebuild
+the ``v3_plans`` table using the standard temp-table-copy-rename approach.
+Child tables (``plan_projects``, ``plan_arguments``, ``plan_invariants``)
+have their FKs re-pointed during the rebuild.

+Feature: Plan phase/state constraint rebaseline
+  As the system operator
+  I want the v3_plans table to accept the Action phase and Apply terminal states
+  So that plans can follow the four-phase lifecycle: Action -> Strategize -> Execute -> Apply
+
+  Background:
+    Given the plan phase rebaseline database is initialized
+
+  Scenario: Phase constraint accepts 'action' phase
+    When I insert a plan with phase "action" and state "queued"
+    Then the plan should be persisted successfully with phase "action"
+
+  Scenario: Phase constraint rejects 'applied' as a phase
+    When I try to insert a plan with phase "applied" and state "queued"
+    Then the insert should fail with a constraint violation
+
+  Scenario: Processing state accepts 'applied' state
+    When I insert a plan with phase "apply" and state "applied"
+    Then the plan should be persisted successfully with state "applied"
+
+  Scenario: Processing state accepts 'constrained' state
+    When I insert a plan with phase "apply" and state "constrained"
+    Then the plan should be persisted successfully with state "constrained"
+
+  Scenario: Default phase is 'action'
+    When I insert a plan using default phase
+    Then the rebaselined plan phase should be "action"
+
+  Scenario: Phase constraint rejects legacy 'applied' phase value
+    When I try to insert a plan with phase "applied" and state "complete"
+    Then the insert should fail with a constraint violation
