fix(hooks): align Claude Code hooks with opencode-cc-plugin reference

100% port verification via Oracle agent parallel checks:
- PreToolUse: recordToolUse(), isHookDisabled(), Object.assign(), error message
- PostToolUse: recordToolResult(), isHookDisabled(), permissionMode, title field
- Stop: isHookDisabled(), parentSessionId, error/interrupt state tracking
- UserPromptSubmit: interrupt checks, recordUserMessage(), log messages

All four hooks now match opencode-cc-plugin/src/plugin/*.ts exactly.
