chore: track audit-runs summary artifacts (md/csv/diff/txt/json/etc)

Snapshot of every non-log artifact under audit-runs/ from audits 003
through 058: findings.md per audit, comparison CSVs, probe diffs,
schema docs, register-dump txts, lr-trace JSONL streams, the saved
canary patch diffs, etc. ~284 files / ~52 MB total.

Excluded (per .gitignore): probe stdout/stderr/log streams (the raw
firehose), guest-memory dumps under audit-026/027/029 (4.5 GB of
.bin files; *.bin pattern added to .gitignore this commit).

Also adds the orphan audit-058-sub825070F0-activation directory that
a subagent accidentally created at project-root instead of
under xenia-rs/audit-runs/; relocated to its proper home.

Purpose: cross-machine continuity. With these summaries committed,
a fresh clone gives the next session the full per-audit context
(findings + tables + cascade predictions) without dependence on
local-only working tree.
