v0.7.1

Added

• Context length in session detail — session detail view now shows the current context window size (input + cache read + cache create tokens)
• Cache read/write breakdown in today card — token detail line splits cache into CRead and CWrite instead of a single combined value

Fixed

• SSE reconnect on server restart — EventSource now properly reconnects with exponential backoff when the server restarts, and refreshes all data on reconnect
• Graph label overlap — memory graph uses more vertical space and truncates long project labels to prevent overlap
• New project directories not detected — file watcher now watches the projects directory itself, so new project dirs are picked up immediately and their existing session files are scanned
