feat: add linkOnPaste prop to EnrichedTextInput (iOS, Android, Web)

[jtatar]

Summary

Adds an opt-in linkOnPaste prop to <EnrichedTextInput /> (iOS, Android, Web).

When enabled, pasting clipboard content that is solely a URL over a
non-empty selection turns the selected text into a link pointing to that
URL, instead of replacing the selection with the pasted text. This is a common
rich-text convenience (it mirrors the "paste URL onto selected text" behavior
of editors like Google Docs, Notion, Slack).

Disabled by default (linkOnPaste={false}), so existing behavior is
unchanged for current users — the feature only activates when explicitly turned
on.

Behavior details:

• The pasted text is recognized as a URL only when it fully matches the
  configured linkRegex (or the default link-detection patterns when
  linkRegex is not set). Clipboard text containing a URL plus other text
  (e.g. see https://example.com) is not treated as a link and falls back
  to a normal paste.
• Scheme-less URLs (e.g. www.example.com) get an https:// prefix in the
  resulting link href, while the visible selected text is preserved.
• Falls back to the normal paste when the selection is empty/whitespace-only,
  or when the link style cannot be applied at the selection (inside inline code
  or a code block).
• Has no effect when link detection is disabled with linkRegex={null}.

Implementation:

• JS: prop on the codegen spec, types.ts, default props (false), and the
  native/web EnrichedTextInput wrappers.
• iOS: gated branch in EnrichedInputTextView's paste:; a new
  tryAddLinkAt:... (returns whether the link was applied) and
  linkURLIfEntireString: on EnrichedTextInputView; a
  matchesEntireLinkRegexWithConfig: full-string variant on LinkStyle.
• Android: gated branch in handleTextPaste; a linkifySelectionOnPaste
  helper plus a linkExactRegex (whole-string) companion to linkRegex, and a
  setLinkOnPaste ViewManager setter.
• Web: handleLinkOnPaste wired into the TipTap editor's handlePaste,
  reusing the existing autolink regex and the EnrichedLink.setLink command
  (which already bails out when the link style is blocked).

Test Plan

Web (automated): added a test-links linkOnPaste suite to
.playwright/tests/links.spec.ts covering: linkifying the selection with a full
URL, https:// prefixing for a scheme-less URL, and the two fallback cases
(non-bare-URL text, and no selection). Run with yarn test:e2e:web. The full
links suite (35 tests) passes.

Manual (all platforms). The example app enables linkOnPaste on its editor
screens. To verify:

1. Type Hello world, select world.
2. Copy a URL that the editor's linkRegex accepts and paste over the selection
   → world becomes a link to that URL (visible text unchanged).
3. Copy a scheme-less form (www.…) → the link href is prefixed with https://.
4. Copy text that is not a bare URL (e.g. see https://…) → normal paste
   (selection replaced, not linkified).
5. Set linkOnPaste={false} → step 2 becomes a normal paste again (selection
   replaced), confirming the default/off behavior is unchanged.

yarn typecheck, yarn lint, and yarn lint-clang all pass; the Android
Gradle lintVerify builds the module cleanly.

Pull request overview

Adds an opt-in linkOnPaste prop to EnrichedTextInput across iOS/Android/Web so that pasting a bare URL over a non-empty selection linkifies the selected text instead of replacing it, matching common rich-text editor behavior while keeping default behavior unchanged.

Changes:

• Introduces the linkOnPaste prop end-to-end (types/defaults, native codegen spec, native + web wrappers).
• Implements platform-specific paste interception/linkification logic (iOS/Android/Web) with “whole-string URL” detection and scheme-less https:// normalization.
• Updates example apps and adds Playwright E2E coverage for Web.
