Subject: [PATCH 2/8] Add lino! macro for compile-time Links Notation parsing

Implement a procedural macro that provides compile-time validation
and convenient syntax for working with Links Notation in Rust.

Features:
- Compile-time syntax validation with clear error messages
- Zero runtime overhead for validation
- Returns fully typed LiNo<String> structures
- Simple and ergonomic API

Implementation:
- Created links-notation-macro crate with procedural macro
- Added basic syntax validation (parentheses, quotes)
- Re-exported macro from main crate via 'macro' feature (enabled by default)
- Added comprehensive test suite with 12 test cases
- Updated documentation with macro usage examples

The macro validates syntax at compile time and calls the runtime
parser, providing the best of both worlds: compile-time error
checking and full parser capabilities.

Related to #201

 ## Usage
 
-### Basic Parsing
+### Using the `lino!` Macro (Recommended)
+
+The `lino!` macro provides compile-time validation and a convenient way to work with Links Notation:
+
+```rust
+use links_notation::lino;
+
+fn main() {
+    // Parse at compile time with validation
+    let result = lino!("papa (lovesMama: loves mama)");
+
+    // The result is a fully typed LiNo structure
+    println!("Parsed: {}", result);
+
+    // Syntax errors are caught at compile time!
+    // This would fail to compile:
+    // let invalid = lino!("(unclosed parenthesis");
+}
+```
+
+The `lino!` macro:
+- ✅ Validates syntax at compile time
+- ✅ Provides clear error messages for invalid syntax
+- ✅ Returns fully typed `LiNo<String>` structures
+- ✅ Zero runtime parsing overhead for the validation
+
+### Basic Runtime Parsing
+
+For dynamic content, use the runtime parser:
 
 ```rust
 use links_notation::{parse_lino, LiNo};

+/// Procedural macro that provides compile-time validation of Links Notation syntax.
+///
+/// This macro takes a string literal containing Links Notation and validates it at compile time.
+/// At runtime, it calls the parser to construct the `LiNo` structure, but any syntax errors
+/// are caught during compilation.
+///
+/// # Examples
+///
+/// ```rust
+/// use links_notation::lino;
+///
+/// // This will be validated at compile time
+/// let result = lino!("papa (lovesMama: loves mama)");
+///
+/// // This would fail to compile with a clear error message:
+/// // let invalid = lino!("(unclosed parenthesis");
+/// ```
+///
+/// # Benefits
+///
+/// - **Compile-time validation**: Syntax errors are caught at compile time
+/// - **Zero overhead**: Simple wrapper around the runtime parser
+/// - **Type-safe**: Returns fully typed `LiNo<String>` structures
+/// - **Convenient**: No need to manually handle parse errors in most cases
+///
+/// # Implementation
+///
+/// The macro expands to code that:
+/// 1. Contains a compile-time validation check
+/// 2. Calls `parse_lino()` at runtime
+/// 3. Unwraps the result (safe because validation passed at compile time)

Subject: [PATCH 4/8] Add direct syntax support to lino! macro

The lino! macro now supports writing Links Notation directly without
string literals, providing a more native and cleaner syntax:

  lino!(papa (lovesMama: loves mama))

instead of:

  lino!("papa (lovesMama: loves mama)")

Both syntaxes are supported - string literals are still needed for
special cases like newlines, quoted strings with spaces, or indented
syntax.

Implementation:
- Add custom token parser (DirectLinoInput) that converts Rust tokens
  to Links Notation string representation
- Handle identifiers, punctuation, literals, and groups (parentheses)
- Support colons for ID separators in Links Notation
- String literal syntax takes precedence for backward compatibility

Testing:
- Add 15 new tests for direct syntax
- Test equivalence between direct and string literal syntaxes
- Test runtime parser equivalence
- All 27 macro tests passing

+The `lino!` macro provides compile-time validation and a convenient way to work with Links Notation. It supports two syntax options:
+
+#### Direct Syntax (Recommended for Simple Cases)
+
+Write Links Notation directly without quotes for a cleaner, more native feel:
 
 ```rust
 use links_notation::lino;
 
 fn main() {
-    // Parse at compile time with validation
-    let result = lino!("papa (lovesMama: loves mama)");
+    // Direct syntax - no quotes needed!
+    let result = lino!(papa (lovesMama: loves mama));
+
+    // Simple triplets
+    let triplet = lino!(papa has car);
+
+    // Nested links with IDs
+    let nested = lino!((outer: (inner: value)));
+
+    // Multiple links
+    let multi = lino!((a x) (b y));
 
-    // The result is a fully typed LiNo structure
     println!("Parsed: {}", result);
+}
+```
+
+#### String Literal Syntax (For Complex Cases)
+
+Use string literals when you need special characters, newlines, or quoted strings:
 
-    // Syntax errors are caught at compile time!
-    // This would fail to compile:
-    // let invalid = lino!("(unclosed parenthesis");
+```rust
+use links_notation::lino;
+
+fn main() {
+    // String literal for content with newlines
+    let multiline = lino!("papa has car\nmama has house");
+
+    // String literal for quoted identifiers with spaces
+    let quoted = lino!(r#"("quoted id": "quoted value")"#);
+
+    // Indented syntax requires string literal
+    let indented = lino!(r#"3:
+  papa
+  loves
+  mama"#);
+
+    println!("Parsed: {}", multiline);
 }
 ```
 
+#### Benefits
+
 The `lino!` macro:
-- ✅ Validates syntax at compile time
-- ✅ Provides clear error messages for invalid syntax
-- ✅ Returns fully typed `LiNo<String>` structures
-- ✅ Zero runtime parsing overhead for the validation
+- **Direct syntax**: Write Links Notation natively without quotes
+- **Compile-time validation**: Syntax errors are caught at compile time
+- **Clear error messages**: Descriptive errors for invalid syntax
+- **Type-safe**: Returns fully typed `LiNo<String>` structures
+- **Zero overhead**: Validation happens at compile time
+
+#### When to Use Each Syntax
+
+| Use Case | Syntax |
+|----------|--------|
+| Simple identifiers | `lino!(papa has car)` |
+| Nested links | `lino!(papa (loves mama))` |
+| Links with IDs | `lino!((myId: value))` |
+| Multiline content | `lino!("line1\nline2")` |
+| Quoted strings with spaces | `lino!(r#"("my id": "my value")"#)` |
+| Indented syntax | `lino!(r#"id:\n  child"#)` |

Subject: [PATCH 5/8] Update .gitignore to ignore Rust workspace build
 artifacts

Add patterns to ignore target/ and Cargo.lock in Rust sub-crates
(e.g., rust/links-notation-macro/).

Subject: [PATCH 6/8] Move macro unit tests to separate file

- Move tests from lib.rs to tests.rs in links-notation-macro crate
- Mark doc examples as `ignore` since they reference links_notation
  which can't be a dependency of a proc-macro crate
- Keep test logic and implementation logic in separate files

Subject: [PATCH 7/8] Reorganize Rust project structure for clarity

Move main crate from rust/ to rust/links-notation/ so the project
structure clearly shows two distinct packages:
- rust/links-notation/Cargo.toml
- rust/links-notation-macro/Cargo.toml

This makes the architecture visible from the directory structure,
as requested in PR feedback.

Subject: [PATCH 8/8] Add workspace configuration and update CI workflow

- Add rust/Cargo.toml as workspace root including both packages
- Update CI workflow to read package info from links-notation/Cargo.toml
- Update cargo publish to specify -p links-notation
- Fix clippy warning in macro crate (collapsible_match)
