Recall a past Claude Code chat by grepping transcript JSONLs

When a user says "remember when we discussed X", grep -li the keyword across ~/.claude/projects/<project-dir>/*.jsonl, sort the hits with ls -t, and skip the current session file. Then parse the JSONL with a short python3 script that prints only user/assistant text blocks (message.content is either a string or a list of {type:text}). For the email half of the task, filter MS Graph list messages on conversationId eq <id> to get the whole thread, including your own sent replies, in one call. A $search on keywords misses short replies that never mention the keyword.
