…oundation Squashed from feat/rust-migration-sdk (WALM-184 commits, split into its own branch/PR so it doesn't keep growing alongside the Rust SDK work): - native Sui transaction building/signing (sui_tx.rs) - Walrus blob discovery off the sidecar (walrus.rs) - RedStuff blob encoding wired natively (walrus_encode.rs) - reserve_space + register_blob PTB construction (walrus_tx.rs) - live n_shards/committee_size + initial_shared_version reads - Upload Relay HTTP client (walrus_upload_relay.rs) - store_blob: complete native Walrus write-path entry point (walrus_write.rs) - WAL coin selection (sui-rpc's official select_coins) + metadata-stamp + transfer-to-owner (1:1 port of blob-metadata.ts), gated behind WALRUS_NATIVE_WRITE (default off) and wired into engine::store_blob - SIDECAR_DISABLED escape hatch in main.rs (still requires the sidecar today — SEAL and Enoki aren't natively migrated yet) SEAL and Enoki still go through the TS sidecar — no viable Rust SEAL crate exists yet, and Enoki hasn't been started. Native Walrus write is opt-in only (WALRUS_NATIVE_WRITE=true) and untested against real testnet funds in this environment (network-restricted sandbox) — needs a live supervised test before enabling anywhere real.

services/server (native Walrus/SEAL sidecar-replacement work) now lives on its own branch/PR (feat/replace-sidecar, PR #375) so it doesn't keep growing alongside the Rust SDK client. Restores services/server to match dev exactly — this branch is now scoped to packages/rust-sdk only.

Split out of feat/rust-migration-sdk (PR #367) so this doesn't keep growing alongside the Rust SDK client work — same commits, own branch.
