* barely got text entry working again

* remove local optimizations

i should really put them somewhere else on my machine

* delete most stuff to get the basics nearly working

* editable text

lots of cloning but seems to be the only way if buffers are in the ECS

editor widgets don't relayout when edited, but when unfocused the buffer does

* fix backspace on native and make basic_ui wasm editable

* fix mid-edit layout

* reimplement text cursor blinking

uhoh it's looking like im using the not a starting point pr as a starting point lol

* update `basic_sprite` example

adds a util crate for common example systems
also removes history tracking structs

* `image_background`+`bevy_api_testing` examples

MV `bevy_api_testing.rs` > `sprite_and_ui_clickable.rs`

* remove `CosmicText` in favor of buffer functions

simplifys API and mirrors Bevy's Text functions more closely

* strip autoheight + example, update other examples

* fix wasm compilation

* clippy

* fix text

* add TODOs

* separate CosmicEdit from display

breaks loads of stuff: sizing, click functions, cursor hovering just a few

Only tested on login example

not optimized; spams handle weak clones to ensure got correct handle (will be fixed by new handle swapping routine)

not sure about the API changes but might just need to get used to it, is much more extensible

* break render function apart

centered padding now broken, not tested other text positions

* reshape earlier in render to fix padding issue

* move image creation to own system

* resize internal sprite to computed UI size

* prevent panic on zero size UI elements

* clicks + editor-display one-to-many relationships

* add render systemset

* fix hoverable invisible sprites

* update examples

* fix auto-height bugs

* clippy

adds a `CosmicCanvas` component to hold the image cosmic draws to. allows easier interop between UI and Sprite widgets

Each type of widget now uses a single `CosmicEditBundle`, adding widget specific components with `.insert()` or as tuples.

should allow a user to install and use the plugin without needing their own install of cosmic-text

the violet color changed slightly when i set all the colors to bevy colors >.<
