chore: add ASF headers to session status files

[Astro-Han]

Problem

main is currently red: npm run check:asf-headers fails with

2 file(s) are missing the ASF license header:
  packages/cli/src/__tests__/tui-session-status.test.ts
  packages/cli/src/tui-session-status.ts

Both files were introduced by #3441. Its CI ran at 2026-08-22T05:55Z, while the ASF source header gate landed later the same day in c633ea5 (2026-08-22T13:48Z), so the PR's green predates the gate and the files merged without headers.

What changes

Headers added by the repository's own tool, npm run write:asf-headers. Nothing else is touched.

Note

This is repair for a merge I performed on a stale green check. Flagging the process gap rather than just the file fix: a check that is green on the exact head can still predate a gate that landed on the base afterwards, so exact-head green needs a freshness dimension too, not only a commit-identity one.

Independent review of exact head 4a4e10901b8f374b00b792320cb192e68cbd05ca: APPROVE — no P0–P3 findings.

The patch adds exactly the canonical 19-line ASF block header to the two previously uncovered TypeScript files and makes no executable-code changes. node scripts/asf-license-headers.mjs check audited 2,757 covered + 130 reviewed exclusions and passed; git diff --check and the current-main merge tree are clean. The exact-head hosted test check is completed / success. All three review endpoints were empty at publication time.

独立审查绑定精确 head 4a4e10901b8f374b00b792320cb192e68cbd05ca：APPROVE，无 P0–P3。 变更仅为两个遗漏的 TypeScript 文件各补仓库标准 19 行 ASF header，没有可执行代码变化。header 审计覆盖 2,757 个文件 + 130 个已审排除项并通过；git diff --check、当前 main merge-tree 和 exact-head hosted test 均通过。发布时三类 review 端点均为空。

Closing as a duplicate: #3589 fixed the same two files and merged at 10:07:36Z, a couple of minutes after I opened this. main is green again on dcebc1e25 and both files carry the header, so there is nothing left for this PR to do.

Apologies for the noise — I opened this without checking whether a fix was already in flight, which is exactly the duplicate-work check I should have run first. Thanks to @1625567290 for getting there first, and to the reviewer who approved this one for the wasted round.
