Yunfei He 688da13872 fix(runtime): keep text-measure helpers internal, matching Ink (#68)
Ink keeps its `measure-text` module internal and never re-exports it. vue-tui
exported `measureText` / `measureTextNatural` from the public index under the
mistaken belief — stated verbatim in commit 0e7d775's own message — that doing
so "matched Ink's public API". It does not; Ink keeps that module internal. A
later design doc then rationalized the leak post-hoc as an intentional
divergence. It was neither intentional nor a divergence — it was a mistake.

Align with Ink:
- Drop both from the public index. `measureTextNatural` stays as an internal
  helper (yoga.ts uses it). `measureText` had zero production callers (yoga uses
  `wrapText` + `measureTextNatural`, never `measureText`) and is removed.
- Integration tests that used `measureText(stripAnsi(x), 9999).width` as a
  line-width helper now use `stringWidth(stripAnsi(x))` directly.
- public-api.test.ts gains a regression test asserting neither is exported.
- Remove the now-obsolete entry from .agents/docs/ink-divergences.md.
