/**
 * Every top-level domain delegated in the root zone, in each form it can appear in
 * a post: ASCII, punycode (`xn--p1ai`) and the Unicode it decodes to (`рф`). This
 * mirrors the list X's own link detection uses, and that parity is the point — a
 * post X turns into a link is exactly a post X bills at the link rate, so a
 * hand-picked subset would leave {@see ContentSanitizer}
 * paying for its own gaps.
 *
 * Regenerate when TLDs are added or retired. Source of truth:
 * https://data.iana.org/TLD/tlds-alpha-by-domain.txt — lowercase every entry and,
 * for each `xn--` one, add `idn_to_utf8()` of it alongside.

-												Defuse links in X posts to avoid the link-post fee (#308)

X bills a post containing a URL at a much higher rate than a plain post, and
its algorithm demotes link posts. The X version of a post now rewrites every
URL non-clickable (https://example.com/post becomes example(.)com/post):
scheme and www. dropped, every dot of the host replaced with (.).

Leaving a single dot intact would still leave a resolvable domain for X to
detect, so all of them are broken. A scheme or www. proves a token is a URL on
its own; a bare host only counts when its last label is a delegated TLD, which
is the one thing telling acme.com apart from Node.js. That check runs against
App\Support\LinkTlds, generated from the whole IANA root zone in every form a
TLD can appear in a post -- ASCII, punycode and the Unicode it decodes to --
because whatever X links is what X bills, so a hand-picked subset would leave
us paying for its gaps. If the regex engine bails out on pathological input the
original content is returned instead of crashing the publisher.

The transform lives in the Platform::X arm of ContentSanitizer, so it reaches
publishing and the app/API/MCP previews from one place and cannot touch any
other network. Off by default; opt in with X_DEFUSE_LINKS.

The editor counts characters and renders its preview client-side and cannot ask
the server on every keystroke, so the rewrite is mirrored in TypeScript. PHP
stays the source of truth: a parity test fails if the two TLD sets drift, and a
browser test drives the real editor so the mirror is covered rather than
assumed. Without it the composer promised text the network never receives.

Character limits now measure the text a reader will see: sanitized, then with
markup resolved away. Measuring the raw draft blocked saving posts that publish
fine and let through posts the network rejects, and counted the editor's HTML
toward the limit. Measuring the sanitized form alone would have counted
Telegram's escaped entities, rejecting messages Telegram accepts.

Empty content is handled once inside the sanitizer instead of by a guard
repeated at every call site.
