README troubleshooting recommends .claudeignore, which Claude Code does not support

[chaosanderos]

The v8 README's Troubleshooting section ('Claude Code prompt cache invalidated after every graphify extract') tells users to add graph.json and graphify-out/ to a .claudeignore file.

Claude Code has no .claudeignore support. Evidence:

• The official docs (code.claude.com/docs, settings page, 'Exclude sensitive files') document permissions.deny Read rules as the mechanism, replacing the deprecated ignorePatterns. No page mentions .claudeignore.
• .claudeignore anthropics/claude-code#579 (the original .claudeignore feature request) was closed with 'You can do this now with deny permission rules!' — no .claudeignore file was ever shipped.
• A long tail of user bug reports confirms the file silently does nothing: [BUG] .claudeignore does not prevent Claude from reading ignored files anthropics/claude-code#36163, #16704, #46699, #56997 ('.claudeignore is silently ignored'), #65812.

So the README's remedy is a no-op: users create the file, nothing changes, and the prompt-cache symptom persists. Suggest either removing the entry or replacing it with the supported equivalent, e.g.:

// .claude/settings.json
{ "permissions": { "deny": ["Read(./graphify-out/**)", "Read(./graph.json)"] } }

(with the caveat that deny rules gate access, which also breaks 'graphify-out/wiki as navigation' workflows — the two goals conflict, which is worth a sentence in the docs).

Found while acting on the same install that produced #1840. Local setup: graphifyy 0.9.13, Claude Code on Linux.

Opened a fix for this: #1877 — swapped the .claudeignore recommendation for the supported permissions.deny Read rules and added a note about the access/cache trade-off.
