docs(wiki): complete v8 "Aurora" wiki — 23 content pages, fact-verified Replaces the v7-era page set with a wiki verified against source commit 124e849 and an execution battery (mingw-w64 build + Wine 8 CLI/GUI matrix, release-binary comparison). 24k words, 488 table rows, 207 wiki-links, 0 QA errors (qa_wiki.py --strict with ban/term lists). New: mechanics canon with decay problem, legacy script editions with verbatim v6/v7 examples and the audit that froze them, guard-watcher page documenting the armed-event-not-waited defect plus shipped fix, configuration/CLI references with measured outputs and exit codes, Oct-2026 competitor landscape, version-drift and reproducibility record, roadmap, glossary. Retained: Independent-Audits.md (v7 audit record; provenance of defect IDs cited by v7 source comments), bannered and relinked.
