* refactor(ecstore): add per-instance InstanceContext, migrate erasure setup type Phase 5 of the global-singleton consolidation (backlog#939): begin moving runtime identity state out of process globals so multiple ECStore instances can coexist in one process. Isolation is carried by the object graph (ECStore -> Sets -> SetDisks holding an Arc<InstanceContext>), not a task-local, which does not propagate across the many internal tokio::spawn boundaries in the data/background paths. This first slice migrates the erasure setup type -- previously three independent process-global bools -- into a single per-instance RwLock<SetupType> that derives is_erasure / is_dist_erasure / is_erasure_sd, removing a triple source of truth that could drift out of sync. - New runtime::instance module: InstanceContext + process bootstrap context. - The legacy free-function facade (is_erasure/update_erasure_type/...) keeps its signatures and forwards to the current instance's context, falling back to the bootstrap context before a store is published. - ECStore gains a pub(crate) ctx field and setup_is_* accessors; its constructors adopt the bootstrap context (never mint a fresh one) so startup writes and post-construction reads share one cell -- single-instance behavior is byte-for-byte unchanged. Tests: erasure predicate derivation vs the legacy behavior, object-graph carrier isolation across two ECStore instances, and bootstrap adoption. Refs: backlog#939 (Phase 5, Slice 1), backlog#653 (item 8) * refactor(ecstore): thread InstanceContext down the object graph (Phase 5 Slice 2) (#4415) * refactor(ecstore): source the namespace lock manager per-instance (#4417) refactor(ecstore): source the namespace lock manager per-instance (Phase 5 Slice 3) Phase 5 Slice 3 (backlog#939): give each instance its own lock namespace by sourcing SetDisks' lock manager from the instance context instead of the process singleton. This removes the false cross-instance mutual exclusion (and attendant ABBA risk) that a shared GlobalLockManager would cause once multiple instances coexist. - InstanceContext gains a `lock_manager: Arc<GlobalLockManager>`. `new()` mints a fresh manager (independent per-instance); `bootstrap_ctx()` aliases the process singleton via get_global_lock_manager(), so a single-instance deployment keeps exactly one shared namespace. - SetDisks::new sources `local_lock_manager` from `ctx.lock_manager()` (the ctx it already adopts), not `runtime_sources::global_lock_manager()`. Single instance: same Arc as before, so behavior is unchanged. - Remove the now-unused `runtime_sources::global_lock_manager()` wrapper. Tests: bootstrap lock manager aliases the process singleton; two fresh contexts own distinct managers; a SetDisks' lock manager is the one from its context and aliases the global singleton in a single-instance build. Verification: cargo test -p rustfs-ecstore (10 Phase 5 + set_disk locking regressions green), cargo clippy -p rustfs-ecstore --all-targets (clean), make pre-commit (pass). Refs: backlog#939 (Phase 5, Slice 3). Stacked on #4415 (Slice 2).
