fix(view): count nested task files

[hutiefang76]

Fixes #1202

Summary

• count every tasks.md under a change directory when computing task progress
• keep root tasks.md behavior intact while supporting layered schemas such as backend/tasks.md and frontend/tasks.md
• add a view regression test for nested task files

Verification

• pnpm vitest run test/core/view.test.ts
• pnpm vitest run test/core/list.test.ts test/core/archive.test.ts test/core/view.test.ts
• pnpm run build
• pnpm run lint
• git diff --check

I used OpenAI Codex to help implement and check this change, and reviewed the diff and test results before submitting.

Summary by CodeRabbit

• New Features

  • Task progress tracking now aggregates information from multiple task files within nested directory structures.

• Tests

  • Added test coverage to verify task progress calculation correctly handles nested directory scenarios.

📝 Walkthrough

Walkthrough

getTaskProgressForChange is refactored to recursively locate all tasks.md files under a change directory using a new findTaskFiles helper, then aggregate task counts across all found files. A new test in view.test.ts validates this behavior with nested backend/tasks.md and frontend/tasks.md files.

Changes

Nested tasks.md Aggregation

Layer / File(s)	Summary
findTaskFiles helper and getTaskProgressForChange refactor src/utils/task-progress.ts	findTaskFiles(dir) recursively traverses subdirectories and returns sorted paths for files named tasks.md. getTaskProgressForChange now calls findTaskFiles, reads each result, and sums { total, completed } from countTasksFromContent across all files. formatTaskStatus is unchanged.
ViewCommand nested tasks test test/core/view.test.ts	Adds a test that writes backend/tasks.md (0/2 complete) and frontend/tasks.md (1/1 complete) under layered-change, executes ViewCommand, and asserts the rendered output shows Task Progress: 1/3 (33% complete) and the ◉ layered-change indicator.

Poem

🐇 Hopping through folders, deep and wide,
No tasks.md now left to hide!
Backend, frontend — count them all,
No nested checkbox shall ever fall.
The view now sees what status knew,
One rabbit fixed it, through and through! ✅

Linked Issues check	✅ Passed	The PR fully addresses issue #1202 by implementing recursive task file detection and aggregating task counts across nested directories, making openspec view consistent with openspec status.
Out of Scope Changes check	✅ Passed	All changes are directly scoped to the stated objective: updating task progress computation in task-progress.ts and adding a regression test in view.test.ts.
