* feat(claudecode): respect Claude Code PermissionRequest hooks When cc-connect bridges Claude Code via --permission-prompt-tool stdio, Claude Code's PermissionRequest hooks are executed but their results are ignored — the control_request is sent on stdout regardless. This fix adds a hook runner in the claudecode agent that independently reads and executes the user's PermissionRequest hooks from ~/.claude/settings.json before forwarding permission requests to the messaging platform. If a hook returns "allow" or "deny", the decision is respected directly. If the hook returns "ask" or no hook matches, the existing behavior (forward to platform) is preserved.

PermissionRequest hooks can check this to skip expensive work (e.g. LLM calls) on the Claude Code side, since the hook result is ignored anyway when --permission-prompt-tool stdio is active. cc-connect's own hook runner explicitly strips this env var so the hook does real work only once — when cc-connect calls it directly. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com> * fix(claudecode): improve cc_hooks protocol compat and test coverage - Add hook_event_name field to hook stdin for Claude Code protocol compat - Change hook timeout from 10s to 60s to match Claude Code's own timeout - Log non-ENOENT errors when loading settings files for debuggability - Return original data on unclosed block comments in stripJSONC - Add tests for multi-entry fallthrough, settings merging, deny message field, CC_CONNECT_PERMISSION_HOOK_SKIP env stripping, timeout, and unclosed block comments Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com> * docs: add Claude Code PermissionRequest hooks section to usage guide Explain that cc-connect re-runs hooks independently (hooks execute twice per request) and document the CC_CONNECT_PERMISSION_HOOK_SKIP env var for LLM-based hooks to avoid double token cost. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com> * refactor(claudecode): load hook settings once per session instead of caching Replace 30s TTL cache with sync.Once — settings are read on first tryHook call and reused for the session lifetime. Avoids repeated JSON parsing on every permission request. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com> * refactor(claudecode): introduce hookContext for richer hook stdin payload Bundle hook parameters into a hookContext struct and add fields that match Claude Code's PermissionRequest hook input spec: permission_mode, transcript_path, permission_suggestions, agent_id, agent_type. Optional fields are omitted from stdin JSON when empty.
