Add FMP node profile negotiation with mixed-profile integration tests

NodeProfile enum (Full/NonRouting/Leaf) with FMP feature bitfield:
bits 0-2 profile, bits 3-6 MMP wants/provides, bit 7 bloom filter
size negotiable. Bloom size TLV always sent with min=max=1KB.

Config mapping: leaf_only -> Leaf, disable_routing -> NonRouting.
Profile and agreed bloom size stored on PeerConnection and
ActivePeer. Handshake msg2/msg3 carry FMP negotiation payload
with profile validation and bloom size agreement.

MMP report sending gated by profile wants/provides. Parent
selection and routing constraints skip non-full peers. One-way
bloom filters for non-routing peers (F inserts N as dependent).
Leaf mode: single-peer enforcement, suppress tree announces and
discovery forwarding.

Mixed-profile integration test: A(Full) + B(Full) + C(NonRouting)
+ D(Leaf) with 9 connectivity assertions.
