feat: add display UI with splash screen, dashboard, and RSSI sparkline

Browse Source 
Implement full SSD1306 OLED display support:
- Splash screen on boot (1.5s) with project name, version, board
- Dashboard showing radio state, config, counters, RSSI/SNR
- RSSI history sparkline (64-sample ring buffer, 2px-wide bars)
- DisplayOn/DisplayOff host commands routed via dedicated channel
- Pure render functions against generic DrawTarget (no hardware coupling)
- Display on/off control bypasses radio task entirely

Compiler version cfg

This crate provides macros for conditional compilation according to rustc
compiler version, analogous to [`#[cfg(...)]`][cfg] and
[`#[cfg_attr(...)]`][cfg_attr].
[cfg]: https://doc.rust-lang.org/reference/conditional-compilation.html#the-cfg-attribute
[cfg_attr]: https://doc.rust-lang.org/reference/conditional-compilation.html#the-cfg_attr-attribute
```toml
[dependencies]
rustversion = "1.0"
```
<br>
## Selectors
- <b>`#[rustversion::stable]`</b>
—<br>
True on any stable compiler.
- <b>`#[rustversion::stable(1.34)]`</b>
—<br>
True on exactly the specified stable compiler.
- <b>`#[rustversion::beta]`</b>
—<br>
True on any beta compiler.
- <b>`#[rustversion::nightly]`</b>
—<br>
True on any nightly compiler or dev build.
- <b>`#[rustversion::nightly(2025-01-01)]`</b>
—<br>
True on exactly one nightly.
- <b>`#[rustversion::since(1.34)]`</b>
—<br>
True on that stable release and any later compiler, including beta and
nightly.
- <b>`#[rustversion::since(2025-01-01)]`</b>
—<br>
True on that nightly and all newer ones.
- <b>`#[rustversion::before(`</b><i>version or date</i><b>`)]`</b>
—<br>
Negative of *#[rustversion::since(...)]*.
- <b>`#[rustversion::not(`</b><i>selector</i><b>`)]`</b>
—<br>
Negative of any selector; for example *#[rustversion::not(nightly)]*.
- <b>`#[rustversion::any(`</b><i>selectors...</i><b>`)]`</b>
—<br>
True if any of the comma-separated selectors is true; for example
*#[rustversion::any(stable, beta)]*.
- <b>`#[rustversion::all(`</b><i>selectors...</i><b>`)]`</b>
—<br>
True if all of the comma-separated selectors are true; for example
*#[rustversion::all(since(1.31), before(1.34))]*.
- <b>`#[rustversion::attr(`</b><i>selector</i><b>`, `</b><i>attribute</i><b>`)]`</b>
—<br>
For conditional inclusion of attributes; analogous to `cfg_attr`.
- <b>`rustversion::cfg!(`</b><i>selector</i><b>`)`</b>
—<br>
An expression form of any of the above attributes; for example
*if rustversion::cfg!(any(stable, beta)) { ... }*.
<br>
## Use cases
Providing additional trait impls as types are stabilized in the standard library
without breaking compatibility with older compilers; in this case Pin\<P\>
stabilized in [Rust 1.33][pin]:
[pin]: https://blog.rust-lang.org/2019/02/28/Rust-1.33.0.html#pinning
```rust
#[rustversion::since(1.33)]
use std::pin::Pin;
#[rustversion::since(1.33)]
impl<P: MyTrait> MyTrait for Pin<P> {
/* ... */
}
```
Similar but for language features; the ability to control alignment greater than
1 of packed structs was stabilized in [Rust 1.33][packed].
[packed]: https://github.com/rust-lang/rust/blob/master/RELEASES.md#version-1330-2019-02-28
```rust
#[rustversion::attr(before(1.33), repr(packed))]
#[rustversion::attr(since(1.33), repr(packed(2)))]
struct Six(i16, i32);
fn main() {
println!("{}", std::mem::align_of::<Six>());
}
```
Augmenting code with `const` as const impls are stabilized in the standard
library. This use of `const` as an attribute is recognized as a special case by
the rustversion::attr macro.
```rust
use std::time::Duration;
#[rustversion::attr(since(1.32), const)]
fn duration_as_days(dur: Duration) -> u64 {
dur.as_secs() / 60 / 60 / 24
}
```
Emitting Cargo cfg directives from a build script. Note that this requires
listing `rustversion` under `[build-dependencies]` in Cargo.toml, not
`[dependencies]`.
```rust
// build.rs
fn main() {
if rustversion::cfg!(since(1.36)) {
println!("cargo:rustc-cfg=no_std");
}
}
```
```rust
// src/lib.rs
#![cfg_attr(no_std, no_std)]
#[cfg(no_std)]
extern crate alloc;
```

//! # Use cases
//!
//! Providing additional trait impls as types are stabilized in the standard library
//! without breaking compatibility with older compilers; in this case Pin\<P\>
//! stabilized in [Rust 1.33][pin]:
//!
//! [pin]: https://blog.rust-lang.org/2019/02/28/Rust-1.33.0.html#pinning
//!
//! ```
//! # trait MyTrait {}
//! #
//! #[rustversion::since(1.33)]
//! use std::pin::Pin;
//!
//! #[rustversion::since(1.33)]
//! impl<P: MyTrait> MyTrait for Pin<P> {
//! /* ... */
//! }
//! ```
//!
//! Similar but for language features; the ability to control alignment greater than
//! 1 of packed structs was stabilized in [Rust 1.33][packed].
//!
//! [packed]: https://github.com/rust-lang/rust/blob/master/RELEASES.md#version-1330-2019-02-28
//!
//! ```
//! #[rustversion::attr(before(1.33), repr(packed))]
//! #[rustversion::attr(since(1.33), repr(packed(2)))]
//! struct Six(i16, i32);
//!
//! fn main() {
//! println!("{}", std::mem::align_of::<Six>());
//! }
//! ```
//!
//! Augmenting code with `const` as const impls are stabilized in the standard
//! library. This use of `const` as an attribute is recognized as a special case
//! by the rustversion::attr macro.
//!
//! ```
//! use std::time::Duration;
//!
//! #[rustversion::attr(since(1.32), const)]
//! fn duration_as_days(dur: Duration) -> u64 {
//! dur.as_secs() / 60 / 60 / 24
//! }
//! ```
//!
//! Emitting Cargo cfg directives from a build script. Note that this requires
//! listing `rustversion` under `[build-dependencies]` in Cargo.toml, not
//! `[dependencies]`.
//!
//! ```
//! // build.rs
//!
//! fn main() {
//! if rustversion::cfg!(since(1.36)) {
//! println!("cargo:rustc-cfg=no_std");
