Subject: [PATCH] The core loads the player's own FrameXML.toc in its order,
 and the boot VM loads no Fonts.xml (#568)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The core now loads the player's own `Interface\FrameXML\FrameXML.toc` off their chain, row by row in its order (`0x6edb90`, from `UI_Init` at `0x48ffed`), instead of benilla's copy of the list, and `benilla.toc` is gone. Order is observable in 1.12.1: event listeners run in registration order, children are kept in creation order, and hit-test ties go to the earlier frame.

- The world VM starts bare: `GlobalStrings.lua` and `Fonts.xml` load as the toc's first rows. The boot VM keeps `GlobalStrings.lua` and the emote tokens, and no longer loads `Fonts.xml`, which nothing reads there (#307).
- A chain without `FrameXML.toc` builds no stock UI and still loads the layer and addons, as the reference does (`"Couldn't open %s"`, severity 2, return unread); benilla reports it as an error.
- Every test kit now loads in the production order, `FrameXML.toc`'s rows then `layer.toc`'s, and a guard fails any kit that loads out of it. Two tests whose premises the stock order disproves are gone.
- `scripts/smoke.sh` counts VMs by the VM marker, since `Fonts.xml` now loads once per world VM.

Verified: new tests for the load list against the chain toc and a reordered fixture toc, the missing-toc case, and two stock frames on one event running in the toc's order (ExhaustionTick before PlayerFrame on `PLAYER_UPDATE_RESTING`), each failing on main's order. A before/after dump of globals, frames, draw order, event listeners and saved variables differs only in stock-order effects: the reordered listeners and children, draw-order ties between non-overlapping frames, and `UnitPopup`'s quality colours now sharing the live tables. `scripts/gates.sh` and `scripts/smoke.sh` are green, and live before/after runs show 0 errors and identical warnings. Built on macOS; no platform seam touched.
