Evan Almloff d8d11db403 Boxed and mapped signals preparing for stores (#4413)
This PR contains just the breaking changes required for the upcoming store implementation. It adds two new primitives:

Mutable mapped signals (without a different subscriber list). This lets you scope a writable value and pass it to a child component. It requires two closures to map the immutable and mutable references to the inner signal. With stores, these closures will be derived
Boxed readable and writable values (ReadSignal, and WriteSignal). Any readable or writable types can be converted to a read signal or write signal with the boxed method or built in types are automatically converted into the boxed variants when passing into props

Evan Almloff b47a6cf83e Move to a generic GlobalLazy<T> (#2851)
* Expose a generic lazy type

* Switch to generic lazy globals

* simplify global lazy context a bit

* rename LazyGlobal to Global

* use Memo::global in more examples

* Fix soundness issue with deref_impl. It relies on the size of self, so it cannot be safe

* add a comment about safety

* Make clippy happy

* fix formatting

* Restore changes to signal impl

* Add helper methods for global signal and global memo to make getting the inner value easier

Jonathan Kelley e42b71b1ba Fix #2612: adjust readable trait to allow try_peek (#2714)
* Fix #2612: adjust readable trait to allow try_peek

Our implementation for Readable was inconsistent.
We had a try_unchecked variant for read but not for peek.
This resolves that by making a breaking change to the
Readable interface.

* fix doctests too

88af3e7eff Hotreloading of for/if/body, formatted strings, literals, component props, nested rsx, light CLI rewrite, cli TUI (#2258)
Hotreload the contents of for loops, if chains, component bodies, props, attributes, and any literals discovered in rsx!
Add a TUI renderer to the CLI.
Improve the CLI build system to be async and parallel.
Refactor RSX to allow partial expansion of expressions.
Merge autofmt implementations for consistency.
Merge the representation of elements and components under the hood.
Add a diagnostics system for rsx for improved error messages.
Drop interprocess and move to websockets for communication between the CLI and the server.
Assign IDs to nodes and attributes in a stable way to be used in non compiler contexts.
Add hotreloading to any body of component/for loop/if chain/etc.
