bynk-syntax 0.142.0

The **syntax foundation of the [Bynk](https://github.com/accuser/bynk)
compiler** — the lowest leaf of the compiler's layered crate set.

It holds the modules every other layer depends *on* and none depend *up* from:

- `lexer` — the [`logos`](https://crates.io/crates/logos)-driven token stream.
- `parser` / `ast` — hand-written recursive descent and the syntax tree it builds.
- `span` — source byte ranges, plus the `line_col` position utility.
- `keywords` — the reserved-word table.
- `error` — `CompileError` (the structured, spanned diagnostic every phase
  produces) and `Severity`.
- `diagnostics` — the registry of `bynk.*` diagnostic codes (the single source of
  truth for the codes, summaries, and grammar links).

Because diagnostics, positions, and codes all live here, they cross every crate
in the compiler without an upward dependency.

## Where it sits

`bynk-syntax` is the leaf of the layered compiler:

```text
bynk-syntax  ◀── bynk-render · bynk-fmt · bynk-check ◀── bynk-emit ◀── bynk-ide
```

The `bynkc`, `bynk`, and `bynk-lsp` binaries are front-ends over this set. Most
users compile Bynk through the [`bynkc`](https://crates.io/crates/bynkc) or
[`bynk`](https://crates.io/crates/bynk) CLIs rather than depending on this crate
directly; it is published so tooling that needs only to lex or parse Bynk can do
so without linking the whole compiler.

## Use

```toml
[dependencies]
bynk-syntax = "0.142"
```

```rust
use bynk_syntax::{lexer, parser};

let tokens = lexer::tokenize(source)?;
let unit = parser::parse(&tokens, source)?;
```
