edde746 66549e3a67 fix(prefs): route every credential read through the tolerant path
The wrong-type recovery only covered reads that went through a
BaseSharedPreferencesService instance. The three stores that hold
credentials read the shared cache directly, so a mistyped value there
still threw a raw TypeError or, for Seerr, was swallowed by a catch-all
and reported as "no session" — the registry documented protection it did
not actually provide.

readPreferenceTolerantly now takes the cache, so CredentialVault,
TrackerAccountStore and SeerrSessionStore get the same classification as
the settings layer. CredentialVault's post-write re-read moves outside
its catch: a wrong-typed value written by another isolate was swallowed
there, and the process then returned a key that never durably landed,
making every ciphertext written under it unreadable on the next launch.

Those stores are consulted long after startup, where a throw is an
unhandled provider error rather than a repair prompt, so SettingsService
initialization now walks the cached key set once and reads every
sensitive key. That puts the failure inside a fatal gate step while the
store is still open and a surgical single-key repair is possible.

The remaining direct reads in settings and storage are routed too; the
only ones left are the library-density dual-type migration, which probes
both types deliberately, and an untyped switch that is type-safe by
construction.

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.
