chore(issue-templates): split bug_report into 3 focused templates

Replaces the single bug_report.yml with 3 templates that each require
only the fields relevant to their bug category. The old form asked every
reporter for URL / selector / runnable repro snippet, which made no sense
for launch failures (no browser to navigate, no element to select) and
overshot for detection reports (proxy region matters more than selector).

  01-launch-failure.yml      browser or wrapper never reaches new_page
  02-site-or-action-bug.yml  browser starts, an op (click / navigate / eval) fails
  03-stealth-detection.yml   a detector flags the browser (FpJS, CreepJS, BotD, ...)

Each template asks for the env basics plus the fields specific to its
category. The site/action one keeps the strict requirements introduced in
the previous template revision (headless, proxy, profile_dir, URL, selector,
runnable repro). The detection one drops selector/profile and asks for
detector name + verdict paste + screenshot. The launch one drops URL /
selector / proxy and asks for install command + full traceback.

Also fixes the contact_links: the old "Bug in the patched Firefox itself"
link pointed to feder-cr/firefox-stealth, a repo that was deleted on
2026-05-19 when source moved to feder-cr/invisible-firefox. Updated to
the new URL and clarified the boundary with the new stealth detection
template (detection results stay in this repo, source-level C++/IDL
patches go in invisible-firefox).
