chore: track pre-production Qwen analyser and redactor wrapper

pz_redact_all.sh is the one-shot Docker wrapper that runs the PHP
ProjectZomboidRedactor over .scratch/pz/Logs/ and produces the
gitignored .scratch/pz/Logs.redacted/ directory consumed by both
the Qwen analyser and the deterministic classifier.

pz_error_analysis.py is the developer-facing Qwen-backed log
analyser: walks the redacted directory, dedupes signatures, and
asks the local sam-desktop Qwen endpoint to classify each unique
shape into a fixed taxonomy with title / cause / fix / confidence.
Runtime depends on the Qwen endpoint; the deterministic classifier
at pz_classify.py is the production-bound counterpart.
