…etheus-scrape-manager Convert scrape.rs into a Cargo workspace along the pure-CPU sync vs async network/runtime boundary: - crates/expfmt (prometheus-expfmt): wire exposition format negotiation, Layer 0 parsers, ArrowDecoder, and Protobuf DTOs. - crates/relabel (prometheus-relabel): target and metric relabeling plus Stage 1/2 dictionary pushdown primitives. - crates/scrape-manager (prometheus-scrape-manager, publish = false for now): workspace home for upcoming discovery, http_config, and scrape manager modules.

…kspace docs Prepare workspace crates for crates.io publication and automated GitHub Release publishing: - Add Apache-2.0 LICENSE at the repository root and symlink into each crate directory so packaged .crate tarballs include the license text. - Add .github/workflows/release.yml using rust-lang/crates-io-auth-action (OIDC Trusted Publishing) and cargo publish --workspace --locked on published GitHub Releases (plus workflow_dispatch --dry-run). - Update README.md, AGENTS.md, and specs/SPEC.md for the three-crate workspace layout.

prometheus/scrape.rsfor publishing to crates.io (unblocking open-telemetry/otel-arrow#4630) by splitting the repository into a three-crate Cargo workspace along the pure-CPU sync vs async network/runtime I/O boundary:prometheus-expfmt(crates/expfmt): wire exposition format negotiation, Layer 0 parsers,ArrowDecoder, and Protobuf DTOs (pure CPU, zero async/network dependencies).prometheus-relabel(crates/relabel): Prometheus-compatible target and metric relabeling plus Stage 1/2 dictionary pushdown primitives (regex,serde,thiserror).prometheus-scrape-manager(crates/scrape-manager,publish = falseuntil discovery and scrape pool PRs land): workspace crate forhttp_config, service discoveries (discovery), and target scrape scheduling (scrape), avoiding theprometheus-scrape/prometheus-scrapername collisions on crates.io.Also adds the Apache-2.0
