fix: lazily load @parcel/watcher in @tailwindcss/cli

[deepshekhardas]

Cherry-pick of PR #20325

[greptile-apps]

Confidence Score: 5/5

The change is safe to merge. It only affects module loading order and error formatting; no build logic, CSS compilation, or watcher behaviour is altered.

The lazy-load refactor is a targeted, low-risk change: a static top-level import becomes a dynamic import wrapped in a try/catch with a clear user-facing error. The formatError consolidation removes duplicated inline code with correct cycle detection. The wordWrap fix addresses a cosmetic edge case without touching any logic paths that matter for compilation output.

No files require special attention.

Walkthrough

The CLI build command now formats errors with wrapped output and recursive cause handling. Watcher loading moved from module initialization to a dynamic import performed before watch-mode setup, with failures reported through the CLI error path. Watch and polling rebuild handlers use the shared formatter. Renderer word wrapping avoids creating an empty line before an oversized word. The unreleased changelog records the watcher-loading fix.
