dhttp v0.2.0

dhttp v0.2.0

DHTTP endpoint facade release for the DHTTP 0.4.0 release wave.

Changes:

• Bump the dhttp workspace release line to 0.2.0 and align Rust, npm, and PyPI package metadata.
• Stage and consume dhttp-identity 0.2.0, including DHTTP certificate-chain key and sequence validation.
• Add public DHTTP DNS planning and construction helpers for endpoint-owned networks and QUIC endpoints.
• Wire endpoint DNS operations into Endpoint::builder() with append-only resolver/publisher configuration and default H3/mDNS/System behavior.
• Make endpoint DNS publishing listen-owned and allow named endpoints with no publishers to listen without starting a publication loop.
• Add Endpoint::from_parts(...) for adapting an existing H3 endpoint, publisher aggregate, and DHTTP network while validating identity and network invariants.
• Update endpoint DNS tests and README dependency examples for the 0.2.0 release line.
• Converge cross-repo release dependencies to published crates.io versions: h3x 0.4.0, dyns 0.4.0, and dhttp-identity 0.2.0.
