Adds Rust as a supported framework, stacked on the Elixir framework PR: - Integration.rust enum entry in the frameworks block, before the language fallbacks - RUST_AGENT_CONFIG in src/frameworks/rust/ — claims a Cargo.toml with a [package] section (workspace-root-only manifests fall through; the agentic monorepo scan finds nested crates), gathers async-runtime presence (tokio/async-std/smol) to steer the agent between the default async client and the blocking one, installs via cargo add posthog-rs - cargoPackageManager helper + FRAMEWORK_REGISTRY entry - bash-fence allowlist for cargo: add/remove/build/check/fmt/clippy/metadata/tree/fetch; run/test stay denied (arbitrary code execution) and install/publish stay denied (outward-facing); the pinned cargo run assertion's reason changes from "no rust framework" to "arbitrary code execution" - Pins framework: rust on a new integration-rust entry in the variant-resolution contract test, matching context-mill PR #269 which must release before this merges - Marks Cargo.toml as a real framework target in the agentic manifest comment Generated-By: PostHog Code Task-Id: 9c949855-7611-48f2-b8b5-7aa4112543e5
