Engram v1.7.0 — Module Path Migration

Migrated the Go module path from alanbuscaglia/engram to Gentleman-Programming/engram to match the canonical GitHub organization.

What Changed

• Module path — all imports now use github.com/Gentleman-Programming/engram/...
• This is a breaking change for anyone importing Engram as a Go library (unlikely — it's a standalone binary)
• No functional changes to the binary itself
