Hikari-miru

- Upgrade alluka to `0.3`.
- Upgrade hikari to `2.0`.
- Add Python 3.13 support.
- Message builders returned by `Menu` and `NavigatorView` now try to set `View.message` when issuing a response through them.
- Fix `self.attr` referring to a `DecoratedItem` instead of the item when using a decorator.
- Fix message builders not passing through flags when using their respective response methods.

- Set `View.message` if a `hikari.Message` is passed to `Client.start_view()`'s `bind_to=`.

- Add the ability to specify view items as classvars, similarly to modals
- Add the ability to pass the title to the modal as a class argument
- Fix `miru.ext.menu.Menu.build_response_async()` ignoring the `ephemeral=` kwarg.
- Fix items created with decorators always having the same custom_ids, even when randomly generated.
- Fix `NavigatorView` default buttons being added when `items=` is specified.
- Remove accidental `typing_extensions` import in `miru.ext.nav`.

This is a major breaking release, adding REST bot support, dependency injection, removing global state from the library, and generally cleaning up old mistakes and weirdness that accumulated over the past 2 years.

Alongside this release comes overhauled [documentation](https://miru.hypergonial.com/), with improved navigation, layout & search and extended examples. If you are looking for the v3 docs, you can find them [here](https://hikari-miru.readthedocs.io/en/v3/index.html).

> [!TIP]
> If you already have an application that depends on v3 of miru, see the [migration guide](https://miru.hypergonial.com/guides/migrating_from_v3/).

- **BREAKING:** Raised the minimum supported Python version to **3.10** or greater.
- **BREAKING:** Change all `miru` decorators to take `Context` as their first argument and the item (button/select etc..) as their second.
- **BREAKING:** Seperate link buttons out of `miru.Button` as `miru.LinkButton`.
- **BREAKING:** Remove `miru.install()`. Use `miru.Client` instead.
- **BREAKING:** Remove `View.start()` and `Modal.start()`. Use `Client.start_view()` and `Client.start_modal()` respectively instead.
- **BREAKING:** Remove `NavigatorView.send()`. Use `NavigatorView.build_response()` instead and send the builder.
- **BREAKING:** Remove `Modal.send()`. Use `Modal.build_response()` instead and send the builder.
- **BREAKING:** Remove `Menu.send()`. Use `Menu.build_response()` instead and send the builder.
- **BREAKING:** Remove `miru.ModalInteractionCreateEvent` and `miru.ComponentInteractionCreateEvent`. Use the unhandled interaction hooks instead.
- **BREAKING:** Made `ViewItem.callback` only accept positional arguments. This is to allow renaming the context variable's name when overriding it in subclasses. This should not affect most people.
- **BREAKING:** Move `miru.Context` to `miru.abc.Context`.
- **BREAKING:** Move `miru.SelectBase` to `miru.abc.SelectBase`.
- **DEPRECATION:** Passing `buttons=` to `ext.nav.NavigatorView()` constructor. Use the newly added `items=` instead. The `buttons=` argument will be removed in v4.2.0.

- Add `miru.Client`. The client manages the state of all currently running views & modals & routes interactions to them.
- Add **RESTBot** support. Simply pass a RESTBot to `miru.Client` when initializing it.
- Add first-class support for **dependency injection**. This allows to better manage state across the library, along with adding better compatibility to `arc` and `Tanjun` via `Client.from_arc()` and `Client.from_tanjun()` classmethods respectively.
- Add the ability to configure `autodefer` at the item level for views. If an item does not specify `autodefer`, the view's setting will be used.
- Add the ability to configure if the autodefer should be ephemeral, along with it's response type through `AutodeferOptions`.
- Stabilize `Context.issued_response`. This property returns a boolean that is `True` if the underlying interaction has already received an initial response.
- Add response builders for entire responses from views or modals.
- Add `Context.respond_with_builder()`.
- Add `Client.set_unhandled_component_interaction_hook` and `Client.set_unhandled_modal_interaction_hook`. These are called when an interaction is received that is not handled by any running modal or view.
- Add `miru.abc.InteractiveViewItem` for all view items that have callbacks. This includes all current `miru.abc.ViewItem` except `miru.LinkButton`.

- Add `miru.ext.menu`, which aims to make creating complex, nested menus easy. See the documentation & example on how to use it.
- Overhaul `View` autodefer logic. `ViewContext` are now automatically deferred if a response is not issued within 2 seconds, even if the callback is still running.
- Add `ItemHandler.get_item_by()` and `ItemHandler.get_item_by_id()`.
- Deprecate `ModalContext.get_value_by_predicate` in favour of `ModalContext.get_value_by`. It will be removed in the next minor release (3.5.0).
- Large amounts of typing improvements across the library.
- Add `CONTRIBUTING.md` and configuration for common editors for better contributor experience.

Fix `View.last_context` and `Modal.last_context` incorrectly casting variable types.
