Expand description

BP-5 (catalog D2 “Per-model-family base-prompt selection”, cx§2 “Per-model base instructions”: “the system prompt is selected per model family from bundled markdown”): the base prompt model should run under, or None when no family pattern matches.

prompts is keyed by a crate::config::glob_match pattern over the model id ("*codex*", "openai/gpt-5.*"). The MOST SPECIFIC match wins, specificity being the pattern’s own length — a TOML table has no order to rely on, so selection must not depend on one. Ties (equal-length patterns both matching) break lexicographically, so the answer is total and reproducible.
