The hook script was draining stdin (`cat > /dev/null`) and using PID walking to find the session ID. For resumed sessions, the PID-based session file contains a different ID than the original JSONL transcript, so `getUsage` could never find the file. Now reads `session_id` from stdin JSON (provided by Claude Code on every hook invocation), which works for both new and resumed sessions. PID walking is retained as a fallback if stdin doesn't contain session_id. Also removes the guard in `updateSessionId` that blocked session ID updates for tabs that already had one — this was a workaround for the PID walking bug and is no longer needed.

Fixes #71
Summary
session_idfrom stdin JSON (provided by Claude Code on every hook) instead of draining stdin and relying solely on PID walking. PID walking is retained as fallback if stdin doesn't contain session_id.Why
For resumed sessions,
~/.claude/sessions/<pid>.jsoncontains a new PID-based session ID that doesn't match the original JSONL transcript.ContextMonitor.getUsage()looks for the JSONL using this wrong ID and never finds it, leaving the context bar empty.Test plan
