feat(render): deprecate pretty helper and option

[emiliosheinz]

Deprecates the pretty helper and options.pretty across node, browser, and edge render paths. Adds JSDoc and inline comments referencing issue #2426 explaining removal goal (dropping Prettier dependency) and migration (call render then run your own formatter). No runtime behavior change unless consumers check new comments.

Follow-up: remove option and dependency in next major after warning period.

Summary by cubic

Deprecates the pretty helper and the options.pretty flag across node, browser, and edge render paths. Adds JSDoc guidance to format rendered HTML yourself; no runtime changes, aligning with the plan to drop the Prettier dependency (see #2426).

• Migration
  • Stop using options.pretty and pretty().
  • Render HTML, then run your own formatter (e.g., Prettier) if needed.
  • Removal planned for the next major release.
