Add Hyprlang lexer (#1286)

Browse Source 
Adds a Hyprlang lexer for Hyprland configuration files.

Closes #1046.

The lexer covers common Hyprland config syntax including variables,
assignments, sections and device sections, exec/source directives,
colors, monitor dimensions, booleans, modifiers, and window-rule command
lists.

Test fixtures were generated for the lexer and analyser.

Validation run locally:

- `RECORD=true go test ./lexers`
- `go test ./lexers -count=1`
- `go test ./... -count=1`
- `./bin/golangci-lint run`
