release 3.0.0: iroh 1.0-rc.0, gossip 0.99, rendezvous 0.2

Pre-upgrade, `Gossip::shutdown()` synchronously published a "remove
self" entry to mainline DHT — that's where the TUI's "updating
DHT..." overlay came from, and it was genuinely slow. The
iroh-gossip-rendezvous 0.1 migration dropped that publish (entries
age out instead), but the shutdown flow didn't change: the overlay
still drew before shutdown ran, and the terminal was restored after.
So `q` would land the user on the misleading screen for as long as
`endpoint.close()` took to flush.

Restore the terminal the instant `q` is pressed, remove the overlay,
and bound `swarm.shutdown()` with a 2s timeout so a slow endpoint
close can't stall the process.

 # Changelog
 
+## [3.0.0] - 2026-05-11
+
+### Breaking
+
+- **`iroh` bumped 0.98 → `=1.0.0-rc.0`** and **`iroh-gossip` bumped
+  0.98 → 0.99**. The bridge is now built on iroh's first 1.0 release
+  candidate. iroh-gossip 0.99 hard-pins `iroh = "=1.0.0-rc.0"`, so the
+  bridge does too until iroh ships a final 1.0 — once it does, this
+  pin will relax to plain `"1"`. Any downstream consumer that pulls
+  iroh transitively must move in lockstep.
+- **`iroh-gossip-rendezvous` bumped 0.1 → 0.2** (now consumed from
+  crates.io; the local path-dep is gone). The 0.2 release of the
+  rendezvous crate carries the same iroh 1.0-rc.0 bump and pins
+  `ed25519-dalek = "=3.0.0-pre.7"` to match iroh-base's pre-release.
+
+### Changed
+
+- `donglora-client` resolves to 1.1.1 (was 1.0.x). Adds the
+  `connect()`-time auto-clamp of `tx_power_dbm` against
+  `GET_INFO.tx_power_min/max` and pre-flight rejection of
+  out-of-range `freq_hz` / `sf` / `bw` with
+  `ClientError::ConfigNotSupported` — both surface as ordinary
+  bridge connection errors today.
+- `Cargo.lock` refreshed end-to-end: `mainline` 6.0 → 6.1.2, plus
+  the usual tokio/rustls/hyper patch sweep.
+
+### Notes
+
+- **Pre-v2 config files were silently mis-loaded.** A stale
+  `~/.config/donglora-bridge/config.toml` from v0.x / v1.x — with
+  `sync_word = 13380` (`0x3444`, the old LoRaWAN-public default),
+  `tx_power = "22"` (old string field), or `cad = true` (removed in
+  v2) — would deserialize without error: serde silently ignored the
+  unknown `tx_power` / `cad` fields and the bridge fell back to its
+  per-field defaults, producing a "requested config" that didn't
+  match what the user had ever entered. On a shared mux the TUI
+  flagged this as a `!` against the active config. Re-run
+  `donglora-bridge config` (or update the file by hand) if your
+  config still has any of `tx_power`, `cad`, or
+  `sync_word = 13380`. A future minor will tighten the loader so
+  this fails loudly instead.
+
+## [2.0.1] - 2026-04-25
+
+### Fixed
+
+- **TUI quit no longer hangs on a misleading "updating DHT" screen.**
+  The 2.0.0 migration to `iroh-gossip-rendezvous` removed the
+  synchronous mainline-DHT publish that the old `Gossip::shutdown()`
+  performed (rendezvous entries age out instead), but the TUI flow
+  was unchanged: pressing `q` drew an "updating DHT…" overlay,
+  awaited `swarm.shutdown()`, and only then restored the terminal —
+  so the user sat on the stale message for as long as
+  `endpoint.close()` took to flush in-flight connections. Restore
+  the terminal the moment `q` is pressed, drop the overlay, and
+  cap the graceful-shutdown wait at 2 s so a slow endpoint close
+  can't stall the process.
+
