[do not merge] dispatch namespaces in dev

[GregBrimble]

Still to do

• [ ] Environments (from a very brief glance at the code, these look like they could be busted across all local dev bindings incl. service bindings/DOs?)
• [ ] WebSockets (I assume supported in prod?)
• [ ] RPC (definitely won't be supported here and the way I've hacked this in is objectively wrong for RPC support, so we need to test what happens in prod and very probably rip out a chunk of what I've done in this PR to fix properly)
• [ ] Dispatching from Pages projects (not supported in prod, but we should probably follow up with that quickly anyway — there's some weirdness in this PR around validation because of it)
• [ ] Does production support non-JSON-stringify-able (e.g. v8 serializable) parameters?
• [ ] In prod, do script env var bindings take precedence over parameters in outbound scripts? Or vice versa? I guessed and made parameters take precedence here.
• [ ] I've pulled up dispatch_namespaces to a non-inheritable config field. It was previously kinda both inheritable and non-inheritable, depending on where you looked in the code.
• [ ] Need to fix the tests in CI incl. the Pages variant (but Workers one works locally 🎉)
• [ ] Confirm happy with --dispatch (very confusing, but vaguely consistent)
• [ ] What happens if I pass in parameters but don't allow-list them in the binding?
• [ ] Does dispatch_namespace in wrangler.toml work for wrangler deploy too?

Hi, would it be possible to update this with the latest main, and publish an NPM release? I'm missing the module aliasing feature that got added later. Thanks.

Closing this since it's no longer referenced in the docs page: https://developers.cloudflare.com/cloudflare-for-platforms/workers-for-platforms/get-started/developing-with-wrangler/ and is pretty stale
