44f88afcf8 docs: add comprehensive language documentation
Documentation structure inspired by Rust Book, Elm Guide, and others:

Guide (10 chapters):
- Introduction and setup
- Basic types (Int, String, Bool, List, Option, Result)
- Functions (closures, higher-order, composition)
- Data types (ADTs, pattern matching, records)
- Effects (the core innovation)
- Handlers (patterns and techniques)
- Modules (imports, exports, organization)
- Error handling (Fail, Option, Result)
- Standard library reference
- Advanced topics (traits, generics, optimization)

Reference:
- Complete syntax reference

Tutorials:
- Calculator (parsing, evaluation, REPL)
- Dependency injection (testing with effects)
- Project ideas (16 projects by difficulty)

15a820a467 fix: make all example programs work correctly
- Add string concatenation support to + operator in typechecker
- Register ADT constructors in both type environment and interpreter
- Bind handlers as values so they can be referenced in run...with
- Fix effect checking to use subset instead of exact match
- Add built-in effects (Console, Fail, State) to run block contexts
- Suppress dead code warnings in diagnostics, modules, parser

Update all example programs with:
- Expected output documented in comments
- Proper run...with statements to execute code

Add new example programs:
- behavioral.lux: pure, idempotent, deterministic, commutative functions
- pipelines.lux: pipe operator demonstrations
- statemachine.lux: ADT-based state machines
- tailcall.lux: tail call optimization examples
- traits.lux: type classes and pattern matching

Add documentation:
- docs/IMPLEMENTATION_PLAN.md: feature roadmap and status
- docs/PERFORMANCE_AND_TRADEOFFS.md: performance analysis

Add benchmarks for performance testing.
