Initial commit: SEO rule engine, auditor, validator, exceptions, mirror

Versioning ~/seo-tools as critical SEO infrastructure (was home-dir only).
Canonical home of seo_rules.py — ResearchOwl will vendor a copy with a CI diff
guard against this repo. No secrets; Ghost access is via the ghst-en wrapper.

+# seo-tools
+
+SEO rule engine + tooling for the Ghost blogs (EN: theexclusionzone.com).
+
+- `seo_rules.py` — shared rule engine (pure functions, no I/O). Single source of truth
+  for thresholds + checks. Consumed by the auditor, the validator, and (vendored) by
+  ResearchOwl's blog pipeline.
+- `seo_audit.py` — Tool A: site-wide auditor (reads all published posts via `ghst-en`).
+- `seo_validate.py` — Tool C: single-post pre-publish validator (`seo-check` wraps this).
+- `seo_exceptions.py` — documented, consciously-accepted waivers (auditor reporting filter).
+- `seo_mirror.py` — OG/Twitter mirroring helper.
+- `phase2_*.py/json` — one-off batch helpers (kept for provenance).
+
+No secrets live here. Ghost access is via the `ghst-en` wrapper (`~/.local/bin`), which
+fetches a staff token on demand from the pod and never writes it to disk.
