Engram v1.10.10 — Correct Version for go install

Users installing via go install now see the correct version instead of dev.

Bug Fix

• Version resolution from Go module info — added a runtime fallback using debug.ReadBuildInfo() that reads the version embedded by Go's module system when ldflags aren't set
• go install github.com/Gentleman-Programming/engram/cmd/engram@v1.10.10 now correctly reports engram 1.10.10
• Goreleaser builds (Homebrew, GitHub release binaries) are unaffected — they continue using ldflags as before
