ed54f95d54 style: rustfmt sweep -- 774 hunks across 154 files -> 0
`cargo fmt --all -- --check` has failed on every run in this repository's
history, identically on `main` and on every branch. This is #12.

Mechanical: `cargo fmt --all`, nothing else. 154 files, all `.rs`, no other
extension touched. `cargo check --workspace` exits 0 afterwards, so nothing
changed semantically.

ON THE ORDERING, WHICH WAS THE REAL QUESTION.

HANDOFF-2026-09-06 section 7 warns this is the expensive fix: a whole-tree
reformat before #7 and #8 return "would put a conflict in every file of 861
commits and make the reviews those items exist to enable unreadable".

That is measurably too pessimistic, and it had been reasoned rather than
tested. Measured here by three-way merging a rustfmt'd `main` against both
unmerged branches, file by file:

  file/branch pairs tested   32
  merges CLEAN               28
  merges CONFLICTING          4   (8 conflict hunks total)

    sylpheed-cli/src/main.rs      1 hunk
    sylpheed-export/src/check.rs  1
    sylpheed-export/src/screen.rs 4
    sylpheed-export/src/video.rs  2

All four are against `auto/frame-blend-draw-path` only;
`auto/port-p6-audio` does not conflict anywhere. The earlier framing --
154 dirty files, 133 that cannot collide, 21 that can, the collision set
carrying 147 of 774 hunks (19%) -- reproduces exactly. What it did not say
is that most of the 21 still merge cleanly, because rustfmt's edits and the
branches' edits rarely land on the same lines.

So the cost of sweeping now is 4 files and 8 hunks for one branch, against
a check that is otherwise red forever. Deliberately NOT folded into the
WASM PR: 154 reformatted files would make that one unreviewable.

Closes #12

da869a518c re(challenge): the EX missions are a MODE, not a stage number
Static-only (no emulator, no pad input). Three findings, each with its own
evidence:

- The disc holds exactly 29 StageResource records in three families --
  S01-S16 story, S18-S23 tutorial (all bg=Original), S24-S29 challenge, plus
  Test. That is 16 + 6 + 6 + 1, matching weapon.tbl's stage01..16 /
  tutorial01..06 / challenge01..06 key set exactly. S17 does not exist.
  GP_CHALLENGE.pak has 0 IDXD objects -- it is the menu screen; challenge
  missions reuse GP_MAIN_GAME_E.pak's records.

- The GamePart id table is at 0x820A1630 (29 ids). Indices are confirmed by
  the image's own RegisterToFactory<N, class silph::GamePart_*> text, not by
  position: GP_CHALLENGE = 26, GP_TUTORIAL = 25, GP_BUNK = 10.

- The stage loader selects its config section from a mission-KIND field at
  object+144: 3 -> EXTRA, 5|6 -> CHALLENGE, else FILE (two independent sites,
  0x82184df0 and 0x82185ed0; two more classify {3,5,6} as one group). The
  constructor sets it to 0 and every write inside the class only clears it,
  and no immediate 3/5/6 store to it exists image-wide -- so the kind is
  supplied by the launching GamePart, never derived from the stage number.

That last point is a mechanism (unproven) for why patching the save's stage
field to 27 kills the load: the record is a challenge stage but the kind stays
FILE. Names an untried, zero-cost discriminator -- try stage 18-23.

Also flagged, not resolved: roster_target says S10 (a STORY stage) still
fields an unharvested unit, which contradicts the "story campaign complete"
claim by one unit.
