v0.4.26

Fixes

• wiki.py (#496): Add encoding="utf-8" to all write_text() calls — fixes crash on Windows cp1252 when articles contain Unicode characters like →
• wiki.py (#497): Deduplicate wiki filenames with _unique_slug() — prevents silent article overwrites when two communities get the same label
• hooks.py (#485): Skip post-commit and post-checkout hooks during git rebase, git merge, and git cherry-pick — prevents unstaged changes blocking --continue
• detect.py (#495): Resolve root path at detect() entry — fixes .graphifyignore patterns from parent directories not matching when graphify is run with a relative path like ./raw
• README.md (#369): Document manifest.json and cost.json gitignore recommendations; add .graphifyignore example for platform install files
