…ure in Wasm (#3206) ## Description - Enables the `netwatch` dependency in Wasm - Un-cfg-s the `netwatch::netmon::Monitor` in `magicsock::Actor` - Enables the `metrics` feature for Wasm by depending on a newer iroh-metrics - Minor: We go back to using `netwatch::ip::is_unicast_link_local`, as we can depend on that in Wasm again now. ## Notes & open questions There's some dependencies: - [x] Needs #3203 to be merged first - [x] Depends on n0-computer/net-tools#14 being merged - [x] And released - [x] Depends on a new release of the `iroh-metrics` main branch (I.e. n0-computer/iroh-metrics#11 being released) Closes #3195 ## Change checklist - [x] Self-review.

Description
Uses
window.navigator.onLineandwindow.addEventListener("online", ...)and friends to listen for network changes.Notes & open questions
I tested this manually in firefox, chromium and gnome's WebKit-based browser.
I'm not sure how easy it would be to set up automated testing for this :SPretty hard. I've at least made sure there's a node.js smoke test for this, so that using the API doesn't fail, even if the underlying
navigator.onLineor "online"/"offline" event listener APIs don't exist.Even if this were run in a browser, it'd be hard to trigger online/offline.
The code generally falls back to not doing monitoring when the platform doesn't support it (e.g. node.js). In that case, you just won't get any events.
