Breaking Changes in v1.0.0

# This was supported in v0.x
config = {
    "version": "v1.0"  # ❌ No longer supported
}

result = m.add(
    "memory content",
    user_id="alice",
    output_format="v1.0"  # ❌ No longer supported
)

# v1.1 is the minimum supported version
config = {
    "version": "v1.1"  # ✅ Required minimum
}

result = m.add(
    "memory content",
    user_id="alice"
    # output_format parameter removed
)

ValueError: The v1.0 API format is no longer supported in mem0ai 1.0.0+.
Please use v1.1 format which returns a dict with 'results' key.
