build(baseline): constituents+generator skeleton

Re-architect the baseline as constituents + a generator script (build-baseline.sh)
instead of a checked-out deployed tree: a deployed Joomla docroot differs from the
repo/source layout, so the script manifest-maps packaged extensions (lib/jmap.py),
places no-source and Cadline files, applies core overrides, excludes malware/data,
and emits out/ = the code baseline the operator HIDS verifier consumes.

Adds RUNBOOK.md (recipe+inventory), PROVENANCE.md (upstream map), malware-iocs.

+# RUNBOOK — building the www.archline.hu baseline
+
+This repo stores the **constituents** of the clean code baseline, not the deployed
+tree. [`build-baseline.sh`](build-baseline.sh) deterministically "deploys" them into
+`out/` — the code docroot that `illusion/hids` (imrcli `vanilla_ref`) diffs the live
+server against. The deployed layout differs from the repo layout, so the build maps
+each constituent to its Joomla-installed location.
+
+## Goal
+
+Reproduce the live www.archline.hu **source files as faithfully as possible, minus
+malware**. Authority = the live docroot (RO mirror); the previous single-commit
+"monolith" baseline is an unvalidated helper only (it dropped manifests and clean
+core files, kept junk — not a target).
+
+## Directory contract
+
+| Dir | Holds | build-baseline.sh step |
+|---|---|---|
+| `core/` | Joomla 3.8.11 official full package (deployed form, installer removed) | 1 — rsync minus demo/data |
+| `packages/<slug>/pristine/` | extracted upstream package (with manifest) | 2 — `lib/jmap.py` manifest-map |
+| `packages/<slug>/cadline.patch` | our legit delta on that module (optional) | 2 — `patch -p1` after map |
+| `deployed/<slug>/` | no-source extension, vetted deployed files (deployed layout) | 3 — direct rsync |
+| `cadline/<slug>/` | Cadline own-code (deployed layout) | 4 — direct rsync |
+| `overrides/*.patch` | Cadline core modifications (vs vanilla) | 5 — `patch -p1` |
+| `malware-iocs.paths` | IOC exclusion safety net | 6 |
+
+Modified module → **two git commits**: pristine (`packages/<slug>/pristine/`) then the
+delta (`cadline.patch`), so `git diff` documents exactly our change vs upstream.
+
+## Build & verify
+
+```
+./build-baseline.sh            # → out/  (the deployed code baseline)
+```
+
+Verification (residual→0, malware/data buckets) lives in **`illusion/hids`** (imrcli),
+which consumes `out/` as the per-vhost `vanilla_ref`. This repo only produces the input.
