edde746 957711a650 fix(startup): lead the damaged-store screen with the repair, not retry
A reporter on #1732 ran three successive builds against a preference store of
10336 bytes, every one of them zero, and reported each as "still failing". The
gate classified it correctly every time and the consented repair would have
cleared it in-process, but nothing on the failure screen said so: Retry was
first, styled `FilledButton`, and autofocused, while `Repair storage` sat beside
it as a tonal afterthought. Retry re-reads the same document, so for a
corrupt-store failure it is an action that cannot succeed however many times it
is pressed — and it was the one the screen recommended.

Repair now takes the primary styling, the focus node and first position whenever
it is offered, and the body text says plainly that retrying will not help.
Retry keeps its place for every other failure, where a locked database or a
denied directory really can change between attempts.

The consent dialog was also promising an outcome it could not always deliver.
Servers and profiles survive a repair only because their tokens are ciphertext
in the database and the key that decrypts them lives in the store, so a store
the key cannot be read out of signs the user out of everything — exactly the
all-zero case. `PrefsRecovery.previewSalvage` reads the damaged file without
touching it, and the dialog now names the real cost from that. The retained copy is
labelled as holding credentials unless the bytes prove otherwise: what the
salvage recovered says nothing about what the file still contains, because a
store truncated mid-value keeps most of a vault key in plaintext while the
salvage pattern — which needs the value's closing quote — matches nothing at
all. Only an all-zero file drops the warning, so the one case that cries wolf
is the one that provably holds no secret.

`describe()` finally carries whether a repair was on offer. That line is the
difference between a report a maintainer can act on and two days of guessing
whether the button was even on screen.

edde746 9ecf8db90f fix(startup): stop offering Retry after a repair that needs a restart
A seed-and-restart repair writes the salvaged credentials straight to disk and
leaves this process's store closed, because the plugin still holds the bad
document in memory. repairCorruptStore says so plainly — "nothing may write a
preference before that restart … the caller keeps the app on the failure
screen precisely so nothing does" — but the caller did not. Clearing the
repairing flag re-enabled Retry, and pressing it reopened onto the stale map,
whose first write would flush it back over the seed and orphan every
ciphertext token in the database.

The repair hook returned a bare bool, which cannot express the difference
between "retry now" and "never retry in this process", so replace it with
StartupRepairResult. The restart case latches terminal state on the bootstrap,
withdraws Retry and Repair rather than grey them out — a disabled control
still invites another press — and says what to do instead, which nothing did:
repairNeedsRestart was a dialog title with no body anywhere. Desktop gets a
Quit button through the existing AppExitService seam; Copy and Upload stay
live everywhere, because a stuck user still needs the diagnostic out.

edde746 7f0cad339c fix(startup): report and repair a failed launch instead of showing "Error"
Since 2.10.0 the whole app sits behind one all-or-nothing initialization
gate, and that gate discarded the only evidence of its own failure. It
caught the error, logged nothing but `error.runtimeType`, rendered an
icon plus the word "Error" plus Retry, and never reported the error
because catching it kept the crash reporter from ever seeing it. There
is no log file on any platform, the buffer is in memory only, a
double-clicked Windows release build has no console, and the log viewer
lives in Settings, behind the gate that just failed. #1732 is the result:
a Windows 11 user whose app will not boot and who cannot produce a single
byte of diagnostic detail.

The gate now names its phases. Each step is wrapped so a throw carries
the phase it came from, replacing a `Future.wait` that discarded every
error but the first and could not attribute it to any of four concurrent
steps. The failure screen renders the phase, the exception type, the
message and an expandable stack, plus copy and upload actions that reuse
the existing log-relay flow. The record is persisted next to the database
so the next successful launch can surface it in Settings > Logs, and it
is reported to the crash reporter explicitly.

Only preferences and the database still gate the launch. Window chrome,
locale, crash-reporting init, TV/performance detection, the image-cache
budget and download storage are best-effort and time-bounded, so a
stalled platform thread degrades instead of holding the splash forever.
Sentry no longer receives the startup work as its `appRunner`: that made
a startup failure indistinguishable from a Sentry failure, and the guard
would then have re-run migrations and the database open a second time.

The two remaining fatal steps become recoverable. Preference reads
tolerate a value whose stored type no longer matches, dropping the key
and defaulting instead of failing the boot. A store that cannot be parsed
is detected before either desktop plugin backend can memoise it, which is
what makes an in-process repair possible at all. Repair is never
automatic: it states what it will cost, salvages the credential-vault key
and every tracker and Seerr session it can validate out of the damaged
bytes, reseeds them, and moves the original aside rather than deleting
it. Servers and profiles survive a salvaged key because their tokens are
ciphertext in the database; tracker and Seerr sessions are plaintext
preference entries, so the copy says they may still need reconnecting.

Nothing derived from the store reaches a diagnostic. `FormatException`
prints an excerpt of whatever it failed to parse, and during startup that
document holds the vault key, refresh tokens and session cookies while
the redaction manager still has nothing registered, so the wrapper keeps
only the cause's type and offset and the record is an allowlist of
already-redacted fields. The quarantined copy is labelled as containing
credentials, is never offered for upload, and can be deleted from the
dialog.

Also self-heals orphaned WAL/SHM sidecars on desktop rather than only
tvOS, makes every `createTable` migration step idempotent, keeps MSVC
link by-products out of the Windows bundle, and asserts bundle contents
in CI.
