v0.5.0

Added

• Battle testing — expanded CI (feature matrix, MSRV, docs, cargo-deny, cargo-semver-checks, weekly fuzz), tests/url_edge_tests.rs, proptest coverage for URL/query/path, criterion benches, and fuzz targets under fuzz/.

Changed

• MSRV — raised to 1.88 (matches current dependency floor, e.g. cookie_store).
• CI — dropped Miri job (low signal with workspace unsafe_code = "forbid").

Fixed

• max_response_bytes on buffered responses — ClientBuilder::max_response_bytes and per-request .max_response_bytes() now apply to send() and send_json(), not only send_stream() / collect(). Bodies are read via the streaming transport when a cap is set; oversized Content-Length headers fail fast with Error::BodyTooLarge.
• Streaming non-2xx bodies — send_stream() preserves the full response body when status is not 2xx and throw() is not set.
