Claude 36c85500bd Add unit tests for parser and codegen
29 tests covering:
- Parser: binding kinds, variadic patterns, literal tokens, ident
  constructs, spread-for detection, escape/template output blocks,
  multi-macro files, comment skipping, error reporting (line/col)
- Codegen: proc_macro fn emission, single/structural/variadic patterns,
  escape blocks, ident construction, keyword vs non-keyword tokens,
  and round-trip tests for the hello and derive_getters examples

Claude e8d835e196 Add misses-rt crate, component example, README, and fix codegen for non-keyword literal tokens
- misses-rt: add Buffer/Markup HTML helpers, name/type helpers, parse_sections/parse_kv, and template AST
- codegen: add is_syn_keyword() — non-keyword idents in patterns now generate parse+compare instead of syn::Token![…]
- parser: split punct vs ident chars in literal pattern tokens so `props:` becomes two tokens
- examples: add component.mrs/.rs demonstrating named literal tokens and tt capture
- README: comprehensive guide covering .mrs syntax, running the compiler, misses-rt helpers, and examples

Claude f90953a3bb Add examples with cargo run --example support
- Move .mrs files into misses-compiler/examples/ alongside .rs runners
- Add lib.rs exposing parse/codegen for use by example binaries and main.rs
- Fix parser: #[attr] vs #[a => b] disambiguation (look for => before ])
- Fix parser: `for` keyword in `impl Foo for Bar` no longer triggers spread
  (is_spread_for lookahead: must match `for <ident> in $<ident> =>`)
- Add derive_getters.mrs: getter methods via spread iteration
- Add make_id_type.mrs: newtype u64 wrapper with From impls, derive attrs

Run with: cargo run --example hello|derive_builder|declare_table|derive_getters|make_id_type

Claude ed62264870 Implement Misses DSL compiler (parser + codegen)
- ast.rs: Full AST for .mrs files (MacroDef, Pattern, OutputBody, TemplateItem)
- parser.rs: Hand-written recursive descent parser with line/col error reporting
- codegen.rs: Transforms AST to Rust proc macro code using syn/quote/proc_macro2
- main.rs: CLI reads .mrs file, runs parse→codegen, writes to stdout or file
- Cargo.toml: Workspace with syn, quote, proc-macro2, prettyplease deps
- examples/: hello.mrs, derive_builder.mrs, declare_table.mrs reference examples

All three reference examples parse and produce prettyplease-formatted Rust output.
Generated code uses syn::parse::Parser closures for structural patterns, quote!
for token templates, spread iteration via .iter().map().collect(), and
format_ident! for identifier construction.
