* fix: rename .claude.json to .openclaude.json with legacy fallback
Rename the global config file from ~/.claude.json to ~/.openclaude.json,
following the same migration pattern as the config directory
(~/.claude → ~/.openclaude).
- getGlobalClaudeFile() now prefers .openclaude.json; falls back to
.claude.json only if the legacy file exists and the new one does not
- Add .openclaude.json to filesystem permissions allowlist (keep
.claude.json for legacy file protection)
- Update all comment/string references from ~/.claude.json to
~/.openclaude.json across 12 files
New installs get .openclaude.json from the start. Existing users
continue using .claude.json until they rename it (or a future explicit
migration).
* test: add unit tests for getGlobalClaudeFile migration branches
Covers the three cases:
- new install (neither file exists) → .openclaude.json
- existing user (only legacy .claude.json exists) → .claude.json
- migrated user (both files exist) → .openclaude.json
