chore(release): v9.1.0 → v10.0.0 (semver-honest major bump)

The v9.0.x → v9.1.0 wave introduced 12 major API breaks per
cargo-semver-checks; Rust semver classifies that diff as a major
version bump. v10.0.0 promotes the v9.1.0 surface to a
semver-honest major version. No further code changes.

Bumped: crates/thetadatadx, ffi, tools/{cli,mcp,server},
sdks/{python,typescript}. All standalone Cargo.lock files
re-locked. tdbe stays at 0.13.1 (no API change). CHANGELOG +
docs-site mirror updated with [10.0.0] entry covering migration
guidance and the breaking-change set carried over from v9.1.0.

Pre-push pipeline: cargo fmt --check, clippy --workspace --locked
-- -D warnings, test --workspace --locked, generate_sdk_surfaces
--check, docs consistency.

+Semver-honest version bump for the v9.1.0 surface. The v9.0.x →
+v9.1.0 wave introduced 12 major API breaks per
+`cargo-semver-checks` (subscribe_*-family removal, polymorphic
+`subscribe(spec)`, `Contract::option` arity change, `Error` enum
+reshape, `FpssData::*` `contract_id` removal in favour of typed
+`Arc<Contract>`, `ThetaDataDx` → `ThetaDataDxClient` rename,
+`mdds::decode::v3` → `mdds::decode::dual_type_columns` module
+rename, `IntoOptionSpec` trait removal, `FpssConnectArgs` field
+additions, `FpssConfig.queue_depth` removal, flat
+`TdxFpssControl` → typed per-variant structs, Go SDK removal).
+Rust semver classifies that diff as a major bump.
+
+v10.0.0 is the v9.1.0 surface with no further code changes —
+bumping the version number to align with semver discipline. The
+audit chain on the v9.1.0 wave (cargo fmt, clippy --workspace
