v2.0.3

Changelog

• 4721b75 End to End Accuracy & confidence factor - how each of this work
• 67ecc17 Feature: Session Boundaries - session history stores at start of mcp/session & user can recall history upto last 5 sessions
• f5e689c Feature: Tool specifically designed people to allow Directories for costwise to indexing, remember & session cache management
• 90691ad Fixed: added .mycli-fts/ to watcher's no-read list to fix this loop, loop: everytime ledger appends something into session_events,jsonl - watcher saw changes - re-index - ledger again append - continue
