feat(llvm): Comprehensive LLVM backend improvements by ChatGPT

Major enhancements to LLVM code generation and type handling:

1. String Operations:
   - Added StringBox length fast-path (length/len methods)
   - Converts i8* to handle when needed for len_h call
   - Consistent handle-based string operations

2. Array/Map Fast-paths:
   - ArrayBox: get/set/push/length operations
   - MapBox: get/set/has/size with handle-based keys
   - Optimized paths for common collection operations

3. Field Access:
   - getField/setField implementation with handle conversion
   - Proper i64 handle to pointer conversions

4. NewBox Improvements:
   - StringBox/IntegerBox pass-through optimizations
   - Fallback to env.box.new when type_id unavailable
   - Support for dynamic box creation

5. Documentation:
   - Added ARCHITECTURE.md for overall design
   - Added EXTERNCALL.md for external call specs
   - Added LOWERING_LLVM.md for LLVM lowering rules
   - Added PLUGIN_ABI.md for plugin interface

6. Type System:
   - Added UserBox type registration in nyash_box.toml
   - Consistent handle (i64) representation across system

Results: More robust LLVM code generation with proper type handling

# Nyash Architecture (Phase 15)
## Scope and Priorities
- Primary execution path: LLVM AOT only. VM, Cranelift JIT/AOT, and the interpreter are not MIR14ready and are considered experimental in this phase.
- Minimize fallback logic. Prefer simple, predictable lowering over clever heuristics that diverge across backends.
## Value Model
- Box = handle (i64) as the canonical runtime representation.
- Strings: LLVM AOT favors i8* for fast path operations and bridging with NyRT. Conversions between i8* and handle exist but are kept to the minimum required surfaces.
## Division of Responsibilities
- NyRT (core, builtin): fundamental boxes and operations essential for bootstrapping/selfhosting.
- IntegerBox, StringBox, ArrayBox, MapBox, BoolBox
- Implemented as NyRT intrinsics (byid shims exist for plugin ABI compatibility).
- Plugins: external or platformdependent functionality (File/Net/Regex/HTTP/DB/GUI etc.).
- ExternCall: minimal window to the outside world (console print/log/error, debug trace, exit/now/readline); other APIs should route through BoxCall.
## Backend Policy (Phase 15)
- LLVM is the source of truth. All new rules and ABIs are documented for LLVM. Other backends will adopt them after LLVM stabilizes.
- Fallback logic must be narrow and documented. If behavior depends on type annotations, the (missing) annotations should be fixed at the MIR stage rather than widening fallback.

# ExternCall Policy (Phase 15)
## Allowed Interfaces (minimal set)
- `env.console.{log,warn,error,readLine}`
- `env.debug.trace`
- `env.system.{exit,now}` (if present)
All other host interactions should go through BoxCall (NyRT or plugins).
## Argumenttypebased selection
- For `env.console.{log,warn,error}` and `env.debug.trace`:
- If the single argument is `i8*` (C string), call the Cstring variant:
- `nyash.console.log(i8*)`, `nyash.console.warn(i8*)`, `nyash.console.error(i8*)`
- `nyash.debug.trace(i8*)`
- Otherwise convert to `i64` and call the handle variant:
- `nyash.console.log_handle(i64)`, `nyash.console.warn_handle(i64)`, `nyash.console.error_handle(i64)`
- `nyash.debug.trace_handle(i64)`
## Rationale
- Keeps the AOT string path fast and avoids accidental `inttoptr` of handles.
- Avoids adding broad implicit conversions in ExternCall; selection is local and explicit.
## NonLLVM Backends
- VM, Cranelift JIT/AOT, and the interpreter may not implement this policy yet (not MIR14ready). LLVM is authoritative; other backends will align after stabilization.

# LLVM Lowering Rules (Phase 15)
This document describes the active LLVM lowering rules used in Phase 15. Only the LLVM path is authoritative at this time.
## General
- Box values are represented as i64 handles when crossing the NyRT boundary.
- String operations prefer i8* fast paths (AOT helpers) when possible. Handle conversions are done only at explicit boundaries.
## NewBox
- StringBox:
- When constructed from a constant string, lowering produces i8* via `nyash_string_new` and keeps it as i8* (no immediate handle conversion).
- Builder skips redundant birth calls for StringBox.
- Other boxes:
- Minimal birth shims exist (e.g., `nyash.box.birth_h`, `nyash.box.birth_i64`) using Box type ids.
## BoxCall: String.concat fast path
- If the receiver is annotated as String (or StringBox), lower to AOT helpers directly:
- `concat_ss(i8*, i8*) -> i8*`
- `concat_si(i8*, i64) -> i8*` (right operand is a handle coerced to string by NyRT)
- `concat_is(i64, i8*) -> i8*`
- For nonString receivers or plugin cases, fall back to plugin/byid paths as needed.
## BinOp Add: String concatenation
- Primary path: AOT helpers selected by operand shapes at IR time:
- `i8* + i8* -> concat_ss`
- `i8* + i64 -> concat_si`
- `i64 + i8* -> concat_is`
- Fallback policy: keep to the minimum. Do not add implicit conversions beyond the above without clear MIR type annotations. If mixed forms miscompile, fix MIR annotations first.
## ExternCall selection (console/debug)
- `env.console.{log,warn,error}` and `env.debug.trace` inspect the argument at lowering time:
- If argument is `i8*`, call the Cstring variant: `nyash.console.{log,warn,error}` / `nyash.debug.trace`.
- Otherwise convert to `i64` and call the handle variant: `nyash.console.{log,warn,error}_handle` / `nyash.debug.trace_handle`.
- The result values are ignored or zeroed as appropriate (sideeffecting I/O).
## Return/Result mapping
- For plugin/byid calls that return an i64 handle but the destination is annotated as pointerlike (String/Box/Array/Future/Unknown), the handle is cast to an opaque pointer for SSA flow. Integers/Bools remain integers.
## Backend Consistency Notes
- VM/Cranelift/JIT are not MIR14ready and may not follow these rules yet. LLVM behavior takes precedence; other backends will be aligned later.
- Any new fallback must be justified and scoped; wide catchalls are prohibited to prevent backend divergence.

# Plugin ABI (by-id / tagged) — Snapshot
This summarizes the ABI surfaces used by LLVM in Phase 15. Details live in NyRT (`crates/nyrt`).
## Fixed-arity by-id shims
- Integer-dominant: `i64 @nyash_plugin_invoke3_i64(i64 type_id, i64 method_id, i64 argc, i64 recv_h, i64 a1, i64 a2, i64 a3, i64 a4)`
- Float-dominant: `f64 @nyash_plugin_invoke3_f64(i64 type_id, i64 method_id, i64 argc, i64 recv_h, f64 a1, f64 a2, f64 a3, f64 a4)`
## Tagged shims (mixed types)
- Fixed (<=4 args): `i64 @nyash_plugin_invoke3_tagged_i64(i64 type_id, i64 method_id, i64 argc, i64 recv_h, i64 a1, i64 t1, i64 a2, i64 t2, i64 a3, i64 t3, i64 a4, i64 t4)`
- Vector (N args): `i64 @nyash.plugin.invoke_tagged_v_i64(i64 type_id, i64 method_id, i64 argc, i64 recv_h, i8* vals, i8* tags)`
Tag codes (minimal):
- 3=int, 5=float, 8=handle(ptr). Others are reserved/experimental.
## Return mapping (LLVM lowering)
- If destination is annotated as Integer/Bool → keep i64 as integer.
- If destination is String/Box/Array/Future/Unknown → cast i64 handle to opaque pointer for SSA flow; do not `inttoptr` where a C string is expected.
## Notes
- These ABIs are used by both built-ins (nyrt) and plugins for consistency.
- The LLVM backend is the reference; other backends will be aligned later.
