v0.3.0

• Makes graph-first package authoring the normal workflow: repository zero.graph stores are the compiler input, .0 files are human-readable projections, zero init owns project creation, zero diff supports graph review, and source projection inputs are rejected at the compiler boundary.
• Adds binary repository graph stores and graph-backed standard-library modules, with source-free status/verify, import/export, merge, query, patch, source-map, reconciliation, metadata, drift detection, and checked-in binary graph fixtures for examples, stdlib, and conformance.
• Advances graph-native compiler execution across check, build, run, test, size, doc, dev, time, package dependency, benchmark, and validation paths, including typed graph-to-MIR lowering, mapped final-MIR cache reuse, graph semantic/resolution/ownership facts, and graph-native test execution.
• Introduces explicit experimental LLVM backend support with backend selection contracts, textual LLVM IR emission, host executable builds, toolchain diagnostics, profile facts, and no-fallback release policy.
• Expands web API support in std.http with routing, JSON response/body validation, CORS, OPTIONS, path segment, bearer token, cookie/session helpers, HTTP listener/client graph lowering, and CRM/router/ping-pong examples.
• Hardens direct backend and compiler internals with C API contracts, unsafe C link validation, target manifest matching, ABI layout tables, direct emit-kind handling, buildability value/target checks, TOML manifests, and stricter metrics guardrails.
• Refreshes public docs, README, bundled skills, graph-first examples, command contracts, conformance, docs tests, aggregate validation, and sandboxed conformance workers around the current agent-facing workflow.
