/**
 * v1.0.1 — `@<slug>` mention syntax for multi-repo intent routing.
 *
 * SoloSquad's value prop is "one agent across multiple repos". The PM
 * already infers target_repo from message content via LLM reasoning,
 * but inference is lossy and expensive. This module gives the user a
 * **zero-cost, deterministic override**: any message containing
 * `@<slug>` where `<slug>` matches a registered repo gets a stable
 * marker injected for the PM to honor.
 *
 * Pattern source: GitHub Slack app's `@<repo>` mention + `/github
 * subscribe owner/repo` (see `docs/plan/v1.0.1-discord-ready-deprecation.md`
 * §3 for the alternatives reviewed). Cheap because routing happens at
 * regex time, before any LLM call.
 *
 * Disambiguation from Discord user pings: Discord mentions are
 * `<@123456789>` (numeric id wrapped in angle brackets). Our pattern
 * matches `@<word-chars>` and then *intersects with the registered
 * slug list* — typos and Discord usernames silently drop through and
 * the message reaches the PM as ordinary text. No false positives.
