Add three new crates and extend the compiler and CLI toolchain: - el-manifest: el.toml manifest parser using serde + toml crate; supports package info, registry/path/version deps, build config with seal key sources, cross targets, and plugins; Manifest::find_manifest() walks up the directory tree - el-registry: HTTP registry client (reqwest + tokio) for packages.neurontechnologies.ai; PackageMetadata, fetch/download/publish/ search, BLAKE3 checksum verification, local cache at ~/.engram/packages/ - el-build: build orchestrator with incremental builds (BLAKE3 file hashes in .el/build-cache.json), cross-compilation target tagging, dep resolution, plugin registry with on_ast/on_typed_ast/on_bytecode hooks, test runner, fmt/check/clean commands - CrossTarget and NativeTarget enums with triple() and artifact_extension() methods; NativeTarget::Host detects compile-time platform via cfg! macros - Plugin system: CompilerPlugin trait + PluginRegistry; dynamic loading is a marked TODO with clear extension point for libloading - CLI extended with: new, add, remove, update, build --cross, run, test, check, fmt, clean, publish, search, plugin add/remove/list; old single-file commands moved to build-file/seal/unseal subcommands - Fix pre-existing debugger.rs borrow error (unwrap_or temporary lifetime) - Fix checker.rs and codegen.rs to handle TestDef/Seed/Assert Stmt variants - Add spec/language.md sections 12-14: package system, build system, plugin system, cross-compilation targets table 130 tests passing, zero warnings
