הורדת Zero 0.3.1

- Hardens compiler, runtime, and toolchain I/O boundaries with checked file reads and writes, directory rejection, atomic output staging, safer executable finalization, mapped-MIR and binary graph parser validation, and regular-file checks for generated compiler/linker outputs.
- Removes remaining shell-based native execution surfaces in favor of argv-based process helpers, safer tool resolution, guarded child setup, validated compiler overrides, and explicit metrics coverage for process and shell-call regressions.
- Expands and hardens the real std.http.listen runtime with per-request spooling, private temp lifecycles, oversized request handling, socket deadlines, structured JSON error responses, and native smoke coverage for listener behavior.
- Grows graph-backed standard-library coverage with environment, filesystem, process, time, random, crypto, URL, JSON, HTTP text/HTML, redirect, array writer, object writer, CLI argument, and HTTP JSON error helpers.
- Improves graph row patch authoring with grouped expressions, compact casts and checks, logical OR, else-if branches, bare returns, natural call arguments, stronger invalid-row diagnostics, and refreshed bundled skill guidance.
- Adds graph build performance instrumentation and budgets, stdlib graph merge caching, agent-scale and Rosetta challenge evals, parallel CI validation jobs, sharded native checks, deep validation profiles, and local aggregate agent checks.
