imre.agent 61d176fb5e feat(archlinexp.eu): add clean deployable baseline on Joomla 3.9.2
Build the archlinexp.eu/www baseline from clean sources on a dedicated
site branch, per the web-baseline deploy model: vanilla Joomla 3.9.2 core
plus the developer-sourced own-code plus a vetted module layer, with the
Cadline core delta applied on the 3.9.2 base. The generator is reused
unchanged: build-baseline.sh is site-agnostic, only the content differs.

Layers:
- core/      vanilla Joomla 3.9.2 official package (installer removed)
- cadline/   own-code from the developer source (beiratkozas, maintenance,
             mod_al_*, mod_alusers, mod_course_list) plus 11 assets that
             the developer source lacks
- deployed/  third-party module slugs taken from live, vetted
- overrides/ the 5 genuine Cadline core modifications, on the 3.9.2 base

The live core carried 31 stale com_users files: the updater skipped the
customized ones, so the version string said 3.9.2 while the code did not.
Taking vanilla 3.9.2 plus the 2 real deltas fixes that silently.

Vetting caught two items that content-based YARA did not flag. Both come
from a structural rule: an extra file on a core-component path that is
not a template override is not a module -- it is a leftover or a plant.
Both are excluded through malware-iocs.paths:
- components/com_mailto/mail.php: an unauthenticated file-write webshell
  (POST save_file + file_content -> fopen/fwrite, no auth check at all),
  present on live since 2021-07-26
- administrator/components/com_joomlaupdate/restoration.php: an Akeeba
  Kickstart leftover carrying a security password (known RCE vector)

Verification: build-baseline.sh -> out/ = 12284 files; YARA (16 rules) on
every source layer and on the built tree = 0 hits; none of the 291 IOC
paths present; no disguised .json dropper; core verified as 3.9.2; the
only extra file left on a core path is the legit Google reCAPTCHA library.
