08416dbd0b fix(viewer,cli,export): clear the remaining 30 clippy lints
`cargo clippy --workspace -- -D warnings` now exits 0. `cargo test
--workspace` still reports 207 passed, 0 failed, 14 ignored across 30
suites — identical to runs 203 and 204, so none of this changed behaviour.

The workspace total was 73, not the 48 run 204 reported. `-D warnings`
turns a lint into a hard compile error, so `sylpheed-formats` failing
stopped its dependents from ever being built: `sylpheed-viewer` (14) and
`sylpheed-cli` (11) had never been linted by anyone. Clearing formats in
bc79817 is what made them visible.

  formats  43 -> 0   (bc79817)
  viewer   14 -> 0
  cli      11 -> 0
  export    5 -> 0

Collision surface, measured rather than assumed. Every viewer file
carrying a lint is byte-identical on both `auto/frame-blend-draw-path`
(495 commits) and `auto/port-p6-audio` (366). All eleven cli sites fall
outside every hunk either branch touches. 68 of the 73 sites could not
collide with anything.

The five that can are all in `sylpheed-export`, and three of those are
real:

  main.rs:278   `&out` -> `out`, inside frame-blend's hunk -278,12
  main.rs:318   `&out` -> `out`, inside port-p6-audio's hunk -303,44
  audio.rs:113  an added `#[allow]` in a file frame-blend DELETES

Each is one line. Resolving the first two means taking the branch's
version and re-applying a borrow removal; the third resolves to the
deletion. Flagged here so neither branch owner meets them cold.

Judgement calls, all stated at the site rather than suppressed globally:

* Three `too_many_arguments` in the viewer are false positives.
  `draw_viewer_ui`, `poll_loader_channel` and `apply_pak` are Bevy
  systems — every parameter is a `Res`/`ResMut`/`EventWriter` the
  scheduler injects, so the count is the framework's dependency list and
  cannot be reduced without a `SystemParam` struct.
* `cmd_screen_render` (cli, 8/7) is a plain function, so that one is real
  if mild; its arguments are the subcommand's flags.
* Two `dead_code` fields in export are serde schema fields. They model
  what the on-disc JSON accepts; deleting them would quietly change that.
* `iso_loader.rs` gains a `FrameRx` alias for the ffmpeg frame channel,
  which is what "very complex type" was asking for.

A site-local `#[allow]` with a reason is a decision recorded where it
applies: one lint, one function, and any new violation elsewhere still
fails the build. That is not the shape PROTOCOL.md forbids.

Closes #13

bc79817488 fix(formats): clear all 43 clippy lints in sylpheed-formats
Run 204 gave this repository its first clippy measurement — 48 errors, 43
of them in `sylpheed-formats`. This clears that 43 to zero under the exact
invocation CI runs, `cargo clippy -p sylpheed-formats -- -D warnings`.

Why this crate first, and why it is safe to touch:

Every one of the 43 sites was checked against the line ranges that
`auto/frame-blend-draw-path` (495 commits) and `auto/port-p6-audio` (366)
actually modify. None of them overlap. Eleven of the fifteen affected
files are byte-identical on both branches, including `mesh.rs` and
`texture.rs`, which carry 28 of the hits between them. The three sites in
`audio.rs`, `ui_layout.rs` and `slb.rs` that live in files those branches
do change fall outside every modified hunk. The collision argument that
defers #12 does not transfer here; it was tested rather than assumed.

It also unblocks a measurement. `-D warnings` turns a lint in this crate
into a hard compile error, so its dependents never build — `sylpheed-cli`
and `sylpheed-viewer` have never been linted at all, and viewer is the
largest crate in the workspace. Both depend only on `sylpheed-formats`
(`sylpheed-export` pins it from a git tag instead), so this commit is what
makes their real counts knowable.

  38  applied by `cargo clippy --fix` — chunks_exact_to_as_chunks,
      manual_div_ceil / is_multiple_of / range_contains, unnecessary_map_or,
      needless_borrow, let_and_return, dead_code, unused_mut/variables.
      Purely local expression rewrites: 38 insertions, 39 deletions.
   2  by hand: a doc continuation that markdown was parsing as a list, and
      `d / frame` behind a `frame > 0` guard becoming `checked_div`.
   3  `#[allow(clippy::too_many_arguments)]` with a stated reason.

On those three allows: 8 parameters against a threshold of 7, in the mesh
anchor path. The real fix is a shared params struct across
`anchor_pool_mesh`, `validate_block` and `validate_block_report` — the
latter two take the same eight arguments and one delegates to the other —
which is a change to the decoder's signatures and belongs to whoever owns
that path, not to a CI-lint pass.

This is not the shape PROTOCOL.md forbids. `continue-on-error` suppresses
everything, present and future, at the job level, and cannot tell "not
yet" from "no longer". A site-local `#[allow]` with a reason is a decision
recorded where it applies: one lint, one function, and any new violation
anywhere else still fails the build.

`sylpheed-export`'s remaining 5 are deliberately untouched — three of them
sit inside hunks both long-lived branches modify, and that crate blocks
nothing. Left for #13.

d8dcc1fc29 docs: record the third softening, which was authored dirty
The two instances already in "Checks that were kind once" were correct
when written and decayed. The third was wrong on its first commit, and it
arrived by a different route: the check and the tree's failure to pass it
land in the same change, so the softening writes itself.

Concretely — the Clippy step had never run (no component in the
toolchain), and the tree is not clippy-clean, so fixing the step and
turning it red are the same commit. The first draft paired the fix with
`continue-on-error: true` and a comment promising removal once the debt
was paid: an expiry date nobody set, in the shape #12's closing line had
already ruled out for rustfmt. Reverted on reading it.

Adds the distinction, a table separating decay from dirty authorship, and
an earlier tell than the mechanical test:

    If you are writing the softening in the same commit as the check,
    the thing you want is an issue, not a flag.

The mechanical test is unchanged and still correct; this only catches the
same failure sooner, at the keyboard rather than at review.
