Subject: [PATCH] p1-2: scaffold kb-parse-md crate
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add the workspace member with the dep allow-list pinned by design §0 Q9
and the task spec. P1-2 will land the frontmatter submodule in the next
commit; P1-3 will add the block parser as a sibling.

Notable choice: serde_yaml (dtolnay) was archived as unmaintained in 2024
so we use serde_yaml_ng, the maintained fork. lingua's per-language
features are explicitly enabled (default-features=false) to keep build
time + binary size sane — only the languages we need at parse time.

+//! This commit only establishes the crate scaffold so subsequent
