our API surface is diffed against the client's 19,572 globals

- `--surface` re-runs the comparison against the captured in-world global table on demand, and `--surface-dump` writes our raw side for any tool to join — a one-shot measurement stops drifting
- CreateFrame with an unresolvable template raises exactly as the client does, instead of handing back a bare frame; `inherits=` is one name, matched case-insensitively
- CreateFontString and CreateTexture honour their third argument — 49 corpus call sites were passing an inherit into the void
- the addon-message inbound byte map is corrected (a test had agreed with the wrong constants), and the group-loot roll template publishes under the reference's own name
