Sækja Zero 0.3.0

- 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.
