fix(hooks): include required hookEventName in hookSpecificOutput JSON

Browse source 
outputWithContext() emitted a hookSpecificOutput object without the
required hookEventName field, so Claude Code rejected the hook output
("hookSpecificOutput is missing required field hookEventName") and
dropped the context the SessionStart, UserPromptSubmit, and PostToolUse
hooks tried to inject. Thread the event name through the helper; each
caller now passes its own (SessionStart / UserPromptSubmit / PostToolUse).
Existing emission tests now assert hookEventName per event.
