Release/v3.8.35

[taylorcox75]

• Fix functional gaps and remove dead code

Wires up Automatic Torrent Management toggling and adds Pause
Downloads/Uploads to the Transfer tab — both were fully implemented
but never reachable from any screen. Also fixes tracker edits to use
the atomic editTracker endpoint instead of remove-then-add (which
could permanently lose a tracker if the add step failed), restores
the missing confirmation toast when disconnecting a server from
Settings, fixes the About screen's React Native version never
falling back to "N/A", and removes the unreachable Copy Hash action
along with its orphaned translation strings.

• Redesign toast positioning to avoid blocking header controls

Toasts previously anchored near the top by default, directly over the
nav-bar band where each screen's own controls live — most visibly the
Search tab's Add button, which a toast would sit on top of after
every add-torrent action, blocking the next tap until it cleared.
Only the torrents list screen had opted in to a header-aware override.

Toasts now anchor near the bottom instead, clearing the tab bar by
default. This removes the entire class of collision at once rather
than requiring each screen to opt in, so the per-screen top-offset
override is no longer needed and has been removed.

• Clean up lint warnings: unused code and loose types

Removes unused imports, variables, and vestigial state across the
app and services layer, drops try/catch wrappers that only rethrew,
attaches cause to a couple of rethrown errors for easier debugging,
and replaces any in test mocks with proper types (ReturnType casts,
ReactTestInstance, etc). No behavior change — internal cleanup only.

• Fix hooks correctness warnings from the newer lint rules

Reorders several data-loading functions to be declared before the
effects that call them (was relying on hoisting order rather than
normal declaration order), converts Animated.Value/PanResponder refs
created via useRef(...).current to useState so they're not read
during render, and reviews every exhaustive-deps warning individually
— adding genuinely missing dependencies where safe, and documenting
why a handful are deliberately excluded (non-memoized loaders, or
values whose object identity churns without their content changing).

A residual set of warnings — mostly "pass a stable handler into a
render-time helper function" and "sync local state when a modal
opens" — are left as-is: they're real patterns used consistently
across this codebase, not bugs, and this project doesn't build with
the React Compiler, so restructuring them now would trade real risk
for no runtime benefit.

• Give the dev-client build a distinct bundle ID

Setting APP_VARIANT=development via eas.json's development profile
env block switches app.config.js to com.taylorcox75.expogo for that
build, so it can install side-by-side with the App Store build on
device instead of overwriting it.

• Fix unreadable dialog button text in dark mode

Filled primary/error buttons colored their label with colors.surface,
which is near-white in light mode but near-black in dark mode — so the
delete confirmation's "Torrent Only" / "With Files" buttons, and the
same pattern in InputModal, LogViewer and the category editor, rendered
dark text on a saturated fill.

Adds an onAccent color (white in every palette) for text sitting on a
filled accent background, and uses it at those four sites. The key is
additive, so saved custom themes keep working and simply inherit the
default. It's intentionally not exposed in the color picker — on-accent
text has one correct value.

Also reverts two changes from the previous commit that traded real risk
for a silenced warning: the render-time nav-readiness ref in _layout.tsx
(the async cold-launch URL handler can resolve before passive effects
flush, and that path has regressed repeatedly), and loadServers' added
showToast/t dependencies (they feed a useFocusEffect, so an unstable
identity there risks a reload loop). Both now carry documented
suppressions instead.

• Move toast notifications back to the top

The bottom position let the keyboard cover a toast on the server
add/edit sheets. Anchoring near the top again avoids that, restoring
the header-offset override for the torrents list screen so its
search/add controls stay clear, and narrowing the toast's side
margins slightly.

• Update README screenshots and fix changelog entry

Replace the old appstore/appstore-ipad PNG screenshots with new JPGs,
lay out the top two README images side by side, and rewrite the
v3.8.35 changelog entry to match what actually shipped.
