MailMaintenanceGate serializes only the backfill↔prune pair. The other two
pairs — sync↔backfill and sync↔prune — are deliberately ungated (foreground
sync uses its own syncMutex to stay UI-responsive) and rely on a disjoint-by-UID
argument for safety, with no test covering it (issue #53).
Add MailSyncConcurrencyTest: a real MailSyncer and a real MailBackfiller/
MailPruner wired to one shared in-memory message store, with CompletableDeferred
gates (mirroring MailMaintenanceGateTest) that park one actor mid-critical-
section while the other's whole critical section runs. Each interleaving is
driven to the boundary (window edge / count floor) where an overlap would
surface as a lost, duplicated, or wrongly-deleted row:
- sync's windowed reconcile runs while a backfill is parked mid-paging just
below the window (tightest edge: lowestSyncedUid == minWindowUid);
- a backfill's below-window page lands after a concurrent full sync of the
window (stale-boundary ordering);
- a count-retention prune runs while a foreground sync is parked in its fetch;
- a full foreground sync runs while a prune is parked inside its critical
section, before it touches the message table.
All four pass: the disjointness invariant holds unlocked. No production code
changed.

Wire the previously-unused ColorSwatchRow into the compose FormattingToolbar
with two new controls: a font-color button applying RichStyle.FontColor and a
highlight button applying RichStyle.Highlight over the selection. Each opens a
ColorPickerDialog built on the shared ColorSwatchRow (~8 font colors; yellow /
green / cyan / pink highlighter markers), with a "no color"/"none" entry that
clears the style outright via a new clearStyle op. Buttons reflect the current
selection's color and carry accessible onClickLabels; swatches carry their own
contentDescriptions.

Follow-up to #148: opening an already-cached message was still slow. Three fixes
on the cached-open critical path (issue #186).
Fix 1 - WebView renders once. The reader resolved cid: inline images AFTER the
first render, so the AndroidView update key (which included inlineImages.keys)
changed and reloaded the whole document a second time for any inline-image email.
ReaderViewModel now resolves inline images and folds them into the SAME state
update as the body, and HtmlBody drops inline images from the reload key, so the
WebView loads exactly once and a late inline-image change never reloads. The
WebView is also destroyed onRelease so it (and its Context) is not leaked.
Pool/pre-warm is left as a TODO (leak-prone; single-render is the dominant win).
Fix 2 - openMessage does no wasted work for a cached, already-read message. Added
a body-less MessageRouting projection (mirrors MessageSummary, no migration);
the routing/flag callers (openMessage's first read, downloadAttachment, setStarred,
deleteMessage, expunge, moveByRole/moveToFolder, buildReplyDraft, prefetchMessage)
route on it, and getById (SELECT *) is reserved for the single read that returns
the body. imapParamsFor (Keystore decrypt + DataStore read) is resolved lazily,
only in the fetch / SEEN-push branches; the cached+read path also skips the
account lookup. De-duped the inlineImages attachment N+1 via a shared
ensureAttachmentFile helper that takes the already-resolved account/folder.
Fix 3 - repository IO off the main thread. openMessage, inlineImages,
downloadedAttachmentParts, and downloadAttachment now run in
withContext(Dispatchers.IO), so their DB/file/crypto work no longer runs on the
Main.immediate viewModelScope during the open animation.
Reader behavior (content, read/SEEN semantics) is unchanged; does not touch the
async SEEN network push handled separately by #170.

Yahoo's guided app-password setup pointed appPasswordHelpUrl at the
generic account-security sign-in page, which assumes the user already
knows to hunt for "Create app password" once there. Point it instead at
Yahoo's own step-by-step "Generate and manage 3rd-party app passwords"
article, mirroring what #153 did for iCloud.
Yahoo does NOT gate app-password creation behind two-step verification
(verified against Yahoo's live help docs, which never list it as a
prerequisite), so — unlike Gmail and iCloud — it keeps twoFactorHelpUrl
null and shows no 2FA button. AppPasswordSetupScreen already renders the
help buttons generically from these provider fields, so no screen change
is needed; the existing PR #152 ordering (2FA link before the
app-password link) is preserved for the providers that have both.
Add a MailProviderTest assertion pinning Yahoo's new app-password URL
(mirroring the iCloud test) and extend the onboarding
yahooSetup_hasNoTwoFactorHelpLink coverage note for #155.
Closes#155

The rich-text engine already fully supported RichStyle.Strikethrough
(HTML serialization, parsing, and rendering); only the toolbar control
was missing. Adds an "S" FormatButton next to Bold/Italic/Underline,
wired the same way (onToggleStyle + isStyled toggle state), plus the
format_strikethrough string resource for its onClickLabel.
