Subject: feat: Phase 3 — stories data model, ValidStoryTransition, storage
 CRUD, API endpoints
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- internal/task/story.go: Story struct, StoryState constants, ValidStoryTransition
- internal/task/task.go: add StoryID field
- internal/storage/db.go: stories table + story_id on tasks migrations; CreateStory,
  GetStory, ListStories, UpdateStoryStatus, ListTasksByStory; update all task
  SELECT/INSERT to include story_id; scanTask extended with sql.NullString for story_id;
  added modernc timestamp format to GetMaxUpdatedAt
- internal/storage/sqlite_cgo.go + sqlite_nocgo.go: build-tag based driver selection
  (mattn/go-sqlite3 with CGO, modernc.org/sqlite pure-Go fallback) so tests run
  without a C compiler
- internal/api/stories.go: GET/POST /api/stories, GET /api/stories/{id},
  GET/POST /api/stories/{id}/tasks (auto-wires depends_on chain),
  PUT /api/stories/{id}/status (validates transition)
- internal/api/server.go: register all story routes
- go.mod/go.sum: add modernc.org/sqlite pure-Go dependency
