chore: prepare dquic v0.7.0-beta.1

[eareimu]

Summary

Prepare the dquic beta release line for v0.7.0-beta.1.

Changed crates:

• qresolve 0.7.0-beta.1
• qtraversal 0.7.0-beta.1
• qconnection 0.7.0-beta.1
• dquic 0.7.0-beta.1

qtraversal and qconnection follow this beta line because their published dependency contract includes qresolve.

Unchanged crates remain on their existing versions, including qmacro, qbase, qevent, qinterface, qprotocol, qdatagram, qcongestion, qrecovery, qudp, and h3-shim.

Release surfaces

• crates.io: qresolve, qtraversal, qconnection, dquic
• GitHub tag/release after merge: v0.7.0-beta.1
• Initial/incremental status: incremental prerelease updates for existing crates

• cargo +nightly fmt --all -- --check
• cargo +nightly clippy --all-targets --all-features -- -Dwarnings

Downstream waits

Downstream beta PRs should wait for these crates to be published and visible on crates.io before final registry-converged merge/tag gates.
