Re-pin CAP-0084 spike deps to the latest fork branch heads and fix the renamed XDR feature flag: - Rust stellar-xdr -> sisuresh/rs-stellar-xdr@7b46a60d (rs-stellar-xdr#549); feature cap_0084 -> cap_0084_muxed_contract (upstream rename). - -curr host/simulation -> sisuresh/rs-soroban-env@8cf4f5e1 (rs-soroban-env#1696); host-curr enables cap_0084_muxed_contract (next alone no longer pulls it in, else the SCAddress match is non-exhaustive). - Go go-stellar-sdk replace -> sisuresh/go@318bde14 (go-stellar-sdk#5960). integration-p28 core image still on the CAP-0083 vnext build; re-pin to the e32fa423-prefixed -vnext once the upstream stellar-core PR (stellar/stellar-core#5332) Jenkins build publishes it.
…bump go-sdk replace to 51284c1e
Advance the CAP-0084 spike's -curr host/simulation deps to the current rs-soroban-env#1696 fork head (87a9b566 -> 448016ac; picks up the anyhow 1.0.103 RUSTSEC-2026-0190 bump). Feature flags unchanged: `next` still transitively enables stellar-xdr/cap_0084_muxed_contract. stellar-xdr stays at 8f826caa: env#1696's head still pins that xdr rev, and cargo must unify preflight's stellar-xdr with the host's into one package. stellar#549's tip (4761390051) is 1 commit ahead but only regenerates JSON schemas (no Rust change), so nothing is lost holding here. Bump both together once env re-pins to the newer xdr rev. Verified: `cargo build -p preflight` resolves to a single stellar-xdr and a single soroban-env-host source and compiles.
The integration-p28-pkg re-pin note pointed at a stale stellar-core commit prefix (e32fa423). stellar-core#5332 head is now b2b06a8; update the deferral comment so the next pass polls for and pins the correct ~vnext build. No functional change (CAP-0083 vnext image still in place).

SPIKE: bumps stellar-rpc's Rust/Go dep chain for Protocol 28 (CAP-0084, muxed contract addresses). Draft — pins to open upstream PR heads.
