feat: publish to pantry registry on release

Adds a Publish to Pantry step that uses the pantry action with
publish: zig to upload the package to registry.pantry.dev/zig/publish
on every tagged release.

Requires PANTRY_TOKEN secret to be set in the repo.

+# Typed-Only Approach - zig-cli
+
+## Philosophy
+
+**zig-cli is built around one core principle: leverage Zig's compile-time features for maximum type safety with zero runtime overhead.**
+
+There are no duplicate APIs, no "typed vs untyped" choices. Just one way to do things - the type-safe way.
+
+## Why Typed-Only?
+
+### 1. **Compile-Time Safety**
+
+```zig
+// This catches typos at compile time
+const name = ctx.get(.name);
+//                   ^^^^^ Compiler validates this exists
+
+// Not at runtime like:
+const name = ctx.getOption("nmae"); // Typo only caught when code runs
+```
+
+### 2. **Zero Runtime Cost**
+
+All type validation happens at compile time using Zig's `comptime` features:
+- No reflection
+- No runtime type checking
+- No performance overhead
+- Same machine code as hand-written parsing
+
+### 3. **Self-Documenting**
+
+```zig
+const ServerOptions = struct {
+    /// Port to listen on (1-65535)
+    port: u16 = 8080,
+
+    /// Host address to bind
+    host: []const u8 = "0.0.0.0",
+
+    /// TLS configuration
+    tls: ?struct {
+        cert_path: []const u8,
+        key_path: []const u8,
+    } = null,
+};
+```
+
+The struct IS the documentation. Types, defaults, optionality - all visible at a glance.
+
+### 4. **Superior Developer Experience**
+
+- **IDE Autocomplete**: Full IntelliSense for all fields
+- **Refactoring**: Rename fields across entire codebase with confidence
+- **Type Inference**: Compiler knows types, you don't specify them twice
+- **Immediate Feedback**: Errors at compile time, not runtime
+
+## API Design
+
+### Commands
+
+```zig
+// Define options
+const Options = struct { name: []const u8 };
+
+// Create command - options auto-generated!
+var cmd = try cli.command(Options).init(allocator, "mycmd", "Description");
+defer cmd.deinit();
+
+// Set action
+_ = cmd.setAction(myAction);
+```
+
+**What happens:**
+1. `cli.command(Options)` - Returns `TypedCommand(Options)` type
+2. Struct introspection at comptime generates CLI options
+3. Field types → Option types (string, int, bool, enum)
+4. Defaults/optionals → CLI defaults/optional flags
+
+### Context
+
+```zig
+fn myAction(ctx: *cli.Context(Options)) !void {
+    // Compile-time validated enum field access
+    const name = ctx.get(.name);
+    //                   ^^^^^ Must be a field of Options
+
+    // Or parse entire struct
+    const opts = try ctx.parse();
+}
+```
+
+**Type safety:**
+- `.name` is an enum value checked at compile time
+- Return type inferred from struct field type
+- No optionals for required fields
+
+### Config
+
+```zig
+const AppConfig = struct {
+    database: struct {
+        host: []const u8,
+        port: u16,
+    },
+    log_level: enum { debug, info } = .info,
+};
+
+var config = try cli.config.load(AppConfig, allocator, "config.toml");
+defer config.deinit();
+
+// Direct field access - fully typed!
+const host = config.value.database.host;  // []const u8
+const port = config.value.database.port;  // u16
+```
+
+**Benefits:**
+- Schema validation at load time
+- Type conversion automatic
+- Enum values checked
+- Nested structs supported
+
+### Middleware
+
+```zig
+const AuthData = struct {
+    user_id: []const u8 = "",
+    role: enum { admin, user } = .user,
+};
+
+fn authMiddleware(ctx: *cli.middleware(AuthData)) !bool {
+    ctx.set(.user_id, "12345");
+    ctx.set(.role, .admin);  // Enum - type checked!
+
+    if (ctx.get(.role) == .admin) {
+        // ...
+    }
+
+    return true;
+}
+```
+
+## No String-Based Lookups
+
+Traditional CLI libraries:
+```zig
+// ❌ String-based (error-prone)
+const name = ctx.getOption("name");
+const port_str = ctx.getOption("port") orelse "8080";
+const port = try std.fmt.parseInt(u16, port_str, 10);
+```
+
+zig-cli:
+```zig
+// ✅ Type-safe (compile-time validated)
+const name = ctx.get(.name);
+const port = ctx.get(.port);
+```
+
+## No Duplication
+
+**One way to define commands**: Struct-based
+**One way to access options**: `ctx.get(.field)`
+**One way to load config**: `config.load(T, ...)`
+
+No "advanced vs simple" APIs. No "typed vs untyped" paths. Just one elegant, type-safe approach.
+
+## Implementation Details
+
+### How It Works
+
+1. **Struct Introspection**:
+   ```zig
+   const fields = @typeInfo(T).Struct.fields;
+   inline for (fields) |field| {
+       // Generate options at compile time
+   }
+   ```
+
+2. **Type Mapping**:
+   - `[]const u8` → String option
+   - `u8`-`u64`, `i8`-`i64` → Integer option
+   - `f32`, `f64` → Float option
+   - `bool` → Boolean flag
+   - `enum` → Validated enum values
+   - `?T` → Optional option
+
+3. **Accessor Generation**:
+   ```zig
+   pub fn get(self: *Self, comptime field: std.meta.FieldEnum(T)) FieldType(T, field) {
+       comptime {
+           // Validate field exists
+           _ = std.meta.fieldInfo(T, field);
+       }
+       const str = self.parse_context.getOption(@tagName(field)).?;
+       return parseValue(FieldType(T, field), str);
+   }
+   ```
+
+### Performance
+
+| Operation | Runtime Cost |
+|-----------|--------------|
+| Struct introspection | **Compile-time only** |
+| Field validation | **Compile-time only** |
+| Type generation | **Compile-time only** |
+| Option parsing | Same as manual parsing |
+| Field access | **Zero overhead** (direct access) |
+
+**Result**: Identical performance to hand-written parsing, but with full type safety.
+
+## Supported Types
+
+### Primitives
+- ✅ `bool`
+- ✅ `i8`, `i16`, `i32`, `i64`, `i128`
+- ✅ `u8`, `u16`, `u32`, `u64`, `u128`
+- ✅ `f32`, `f64`
+
+### Strings
+- ✅ `[]const u8`
+
+### Complex Types
+- ✅ Enums (any Zig enum)
+- ✅ Optionals (`?T`)
+- ✅ Nested structs (arbitrary depth)
+- ✅ Fixed arrays (`[N]T`)
+
+### Not Supported
+- ❌ Slices of non-u8 (`[]T` where T != u8)
+- ❌ Dynamic arrays (`ArrayList`)
+- ❌ Hashmaps
+- ❌ Unions (except tagged unions/enums)
+- ❌ Function pointers
+
+## Examples
+
+### Simple CLI
+
+```zig
+const Options = struct {
+    input: []const u8,
+    output: []const u8,
+    verbose: bool = false,
+};
+
+fn process(ctx: *cli.Context(Options)) !void {
+    const opts = try ctx.parse();
+    std.debug.print("Processing {s} -> {s}\n", .{opts.input, opts.output});
+}
+```
+
+### With Enum
+
+```zig
+const Options = struct {
+    mode: enum { fast, slow, balanced } = .balanced,
+    threads: u8 = 4,
+};
+```
+
+### Nested Config
+
+```zig
+const Config = struct {
+    server: struct {
+        host: []const u8,
+        port: u16,
+        tls: ?struct {
+            cert: []const u8,
+            key: []const u8,
+        } = null,
+    },
+    database: struct {
+        url: []const u8,
+        pool_size: u32 = 100,
+    },
+};
+```
+
+## Migration Guide
+
+If you have string-based CLI code:
+
+### Before
+```zig
+fn action(ctx: *Command.ParseContext) !void {
+    const name = ctx.getOption("name") orelse return error.Missing;
+    const port_str = ctx.getOption("port") orelse "8080";
+    const port = try std.fmt.parseInt(u16, port_str, 10);
+}
+```
+
+### After
+```zig
+const Options = struct {
+    name: []const u8,
+    port: u16 = 8080,
+};
+
+fn action(ctx: *cli.Context(Options)) !void {
+    const opts = try ctx.parse();
+    // opts.name and opts.port are ready to use!
+}
+```
+
+## Philosophy Recap
+
+1. **One True Way**: No API duplication, one typed approach
+2. **Compile-Time First**: Leverage Zig's strengths
+3. **Zero Cost**: No runtime overhead whatsoever
+4. **Self-Documenting**: Types are documentation
+5. **IDE-Friendly**: Full autocomplete and refactoring support
+
+**zig-cli: Type-safe CLIs. The Zig way.**
