fix: add scoped error logging for lexer/parser errors
- Add std.log.scoped(.pugz) to template.zig and view_engine.zig - Log detailed error info (code, line, column, message) when parsing fails - Log template path context in ViewEngine on parse errors - Remove debug print from lexer, use proper scoped logging instead - Move benchmarks, docs, examples, playground, tests out of src/ to project root - Update build.zig and documentation paths accordingly - Bump version to 0.3.1

//! Check list tests - validates pug templates against expected HTML output.
|
||||
//! Each test embeds a .pug file and its matching .html file at compile time.
|
||||
//!
|
||||
//! NOTE: Many tests are disabled because they require features not yet implemented:
|
||||
//! - JavaScript expression evaluation (e.g., `(1) ? 1 : 0`, `new Date()`)
|
||||
//! - Filters (`:markdown`, `:coffeescript`, `:less`, etc.)
|
||||
//! - File includes without a file resolver
|
||||
//! - Runtime data variables (tests expect `users`, `friends` etc.)
|
||||
//!
|
||||
//! Tests that pass are those with:
|
||||
//! - Static content only (no JS expressions)
|
||||
//! - No include/extends directives
|
||||
//! - No filters
