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

-# 🔴 AND THE PIN HAD A COST NOBODY PRICED IN: it made this repository depend on
-# its OWN history by tag. The issue-#49 history rewrite replaced every commit,
-# the locked rev vanished, and the build broke for every clean checkout while
-# still working on the machine that did the rewrite, because its `~/.cargo/git`
-# still held the old object (PR #60). A path dependency cannot fail that way.
-sylpheed-formats = { path = "../sylpheed-formats" }
+# The tag carries the CORRECTED keyframe association: a placement group is an
+# 8-byte header then `frames` x {u32 time; 36-byte pose}, so pose 0's time is the
+# group's lead-in word and EVERY POSE IS TIMED, including the last. The working
+# tree's copy still has the retired `SYLPHEED_KF_TIME_SHIFT` knob -- a superseded
+# partial fix that got the association right but left pose 0 untimed, which is
+# why testing it moved the untimed frame from last to first instead of removing
+# it. The old reading is behind `SYLPHEED_KF_TIME_LEGACY=1` here.
+#
+# 🔴 THE COST, STATED: `sylpheed-cli` builds from the WORKSPACE crate, so until
+# this lands on `main` the exporter and the reference renderer read DIFFERENT
+# decoders and `tools/port/verify-screen` is comparing two eras rather than
+# detecting drift. `tools/port/verify-capture` is unaffected -- it compares the
+# port against oracle CAPTURES and never touches the CLI -- and it is the check
+# that matters. Revert to the path dependency the day the tag is an ancestor of
+# `main`.
+# Bumped c -> d 2026-08-29. What I wanted from the new state: `d` carries parser
+# and `audio.rs` changes on top of `c`. ⚠️ Its headline change -- Reborn's
+# renderer drawing `rotation_deg`, and `compose` drawing a leaf that carries
+# geometry -- does NOT reach this port from here: `sylpheed-cli` builds from the
+# WORKSPACE crate, so the reference renderer stays unrotated until the tag lands
+# on `main`. This bump is for the parser, not for the renderer.

-//! 15 % too small to hold them. One of the two spans is not what the other thinks

-//! packets = 487 424 B**, a whole number of packets — which is what a start offset
-//! looks like, not corruption.
-//!
-//! So: walk the region start backwards and report where `to_xma_riffs` first
