The 3x-ui session cookie is Path-scoped to the panel base path, so the
diag vhost locations can never see it directly. Instead a bridge
location under the panel path (/<panel_path>/diag) validates the
session with auth_request against GET <basePath>/panel/ (sent with
X-Requested-With: XMLHttpRequest so 3x-ui answers 401 instead of a
login redirect), then issues a path-scoped diag_key cookie and
redirects to the diagnostics page. All diag locations return 404
without that cookie.
auth_request runs in the access phase while "return" runs in the
rewrite phase, so the success path hops through try_files to a named
location; the cookie is set only there, never on the 401 redirect.
Replaces the previous ?key= token link, which is removed entirely.

Bug fixes:
- Root check: exit with message instead of "sudo su -" (which continued
the script as non-root after the shell exited)
- Move destructive cleanup into clean_previous_install(), called after
domain validation - wrong args no longer wipe a working install
- x25519 keygen: use xray-linux-$(_arch) instead of hardcoded amd64,
with fallback for renamed ARM binaries
- Cert renewal: certs are standalone-issued, so renew with pre/post
hooks stopping nginx instead of --nginx (which could not bind :80)
- Drop ngx_stream_geoip2 load_module insertion: module was never
installed or used and broke nginx -t when the .so was absent
- emoji_flag: 10s curl timeout + fallback when ipwho.is unavailable
- Uninstall: rm -f /usr/bin/x-ui (trailing slash made rm fail on file)
nginx >= 1.25.1 deprecates "listen ... http2"; emit "http2 on;" there
and keep the old syntax on older versions (Debian 12, Ubuntu 24.04).
Results screen: drop certbot/ssl cert dumps and Clash sub links, keep
panel URL + credentials + diagnostics. Update CLAUDE.md to current
repo state.

Single 512 MB POST over HTTP/2 was throttled by the per-stream h2
flow-control window, reading ~4x low. LibreSpeed uses parallel upload
streams measured via XHR progress events, which amortizes the window
limit (h2 must stay on for trojan-gRPC).
- Vendor speedtest.js + speedtest_worker.js (LGPL) into assets
- mtr-backend.py: ThreadingHTTPServer, /api/st/up upload sink,
/api/st/getip; parallel streams need concurrent handling
- nginx: speedtest locations without limit_req (limit_conn instead),
ping answered by nginx directly, h2 preread/body buffer tuning
- No telemetry, no database
- Drop 512 MB test file; patch script now also substitutes
