Initial release: v0.1.0

Passphrase-based peer rendezvous for iroh-gossip swarms over the public
Mainline DHT. Two nodes that share a passphrase + application salt find
each other and join the same gossip topic — no bootstrap server, no
prior knowledge of peer addresses.

The algorithm is a clock-free variant of HyParView-style partition
healing on BEP 44 mutable items, with K-sharded slots, logical aging
with random-tie eviction, vouching of up to V neighbors at age 1, and
a two-layer AEAD record envelope. Full spec in PROTOCOL.md.

Ships with:

* 119 tests (unit / property / integration / doctest) all green
* 100% mutation-testing catch rate (cargo-mutants)
* cargo-fuzz harnesses for the parse surface
* Kani proofs of no-UB / no-panic on crypto::epoch_of and
  wire::decode_entries across their full symbolic input spaces
* Stateright distributed-system model: safety invariants S1 + S2
  proved exhaustively for N ≤ 6, K ≤ 3; liveness witness under weak
  fairness
* Miri green on the synchronous modules
* cargo-deny + cargo-audit clean
* criterion benches
* Full-matrix CI (Linux + macOS + Windows × stable + MSRV 1.93.0)
* Dedicated nightly lane for Miri / mutation / fuzz / Kani / Stateright
