Stage 3 of the ComlineProject/core#219 rollout, part 1: the runtime's names checked against the catalog.

• Re-vendors the specification at 69d8832. That version includes the comline-catalog crate (specification#2) at spec/rust. Its only other change is the crate's docs.
• Path dependency, not a git rev. comline-catalog is a path dependency on spec/rust, so it is always the revision spec/REV pins, and it builds without fetching. That makes "the crate and the vendored spec move together" hold by construction instead of needing a CI check. It joins the workspace as a member.
• Conformance crate:
  • The fact_values! enums now carry their catalog id (FACT) and an ALL list, and Fact::name returns the catalog ids.
  • facts_are_the_catalogs requires the typed facts to be exactly the catalog's, each enum's values to be the catalog's in order, and every official profile to state exactly its kind's catalog facts.
  • A mutation check confirmed it: reordering Calls fails the test.
• comline-runtime:
  • The wire-name constants stay literal, so the crate still has no dependency for them.
  • tests/catalog.rs, through a dev-dependency, holds each constant to the catalog (value and kind), and checks that every official encoding has one.
• Conformance README: a paragraph on the crate.

Tested locally:

• The conformance, reference and catalog suites pass.
• vendor-spec.sh --check and check.sh pass.
• The wasm32 ffi build and the no_std core build both build.
• Clippy reports nothing new.

Next, part 2: one list of fuzz targets, held against the fuzz Cargo.toml, fuzz.yml and the README.
