The SDK package bump that follows the antd 0.15.0 release. Only antd-rust's public API changed since the 0.2.0 packages, so it is the only package bumped.

This PR

antd-client (antd-rust) 0.2.0 → 0.3.0, a minor bump:

• 0.3.0 is the first version with the byte-range methods from feat(antd-rust): byte-range stream methods on the REST and gRPC clients #317: data_stream_range and data_stream_public_range on both Client and GrpcClient.
• It also adds AntdError::RangeNotSatisfiable. AntdError is not #[non_exhaustive], so the new variant breaks a match without a catch-all arm.

Docs and text:

• The range method docs say they need antd >= 0.15.0.
• The error for a daemon that ignores the range now ends "upgrade to antd 0.15.0 or later", the same text antd-go uses since chore(antd): bump version to 0.15.0 #323.
• README:
  • dependency line antd-client = "0.3";
  • the compatibility note said "Tested against antd 0.12.x"; it now says ranges need antd 0.15.0 and the rest of the API works with 0.14.x;
  • "new in 0.3.0" markers on the range rows and the error row;
  • an "Upgrading from 0.2.x" note for the new variant.

Not bumped

Package	Changes since its 0.2.0 release	Why no new version
antd-py, antd_client (Dart), antd (Ruby)	Regenerated gRPC stubs (#315) and regen scripts and READMEs (#318, #320)	The stubs gain the offset/length request fields, but none of these clients calls them, so their public API is unchanged
@withautonomi/antd (JS), Autonomi.Antd (C#), autonomi/antd (PHP), antd-mcp	None	Nothing changed
antd-go	Range API	Already released as antd-go/v0.15.0 with the daemon tag

Publishing

antd-client has never been on crates.io. publish-rust.yml needs a CARGO_REGISTRY_TOKEN on the crates-io environment for the first publish, and no such secret exists at environment or repo level yet. So after this merges, a rust-v0.3.0 tag would fail at the publish step. Push the tag once the token is in place; after the first publish, trusted publishing can replace it.

Testing (Windows)

• cargo fmt --check, cargo clippy --all-targets --all-features --locked -D warnings and cargo doc --locked --no-deps are clean.
• cargo test --locked: 139 tests pass across the unit, integration and doc-test suites.
• cargo publish --dry-run --locked packages and builds antd-client 0.3.0.
• The range methods themselves passed the 4.5 GiB devnet acceptance on dev2 against an antd built from main before the release.
