Do not treat an unreadable marker as an unmanaged install.

Effect.option converts every readFileString failure into None, not only a missing package-type file. If a package installation has an unreadable marker, runUpdate receives undefined and continues with self-update work.

Distinguish a missing marker from other read errors. Fail with CliUpdateError, or classify non-ENOENT failures as "unknown".

Based on learnings: do not collapse persisted-value read errors into normal absence.

In `@apps/server/src/cli/update.ts` at line 126, The update flow around
readFileString and Effect.option must distinguish a missing package-type marker
from other read failures. Preserve the absent-marker behavior for ENOENT, but
propagate non-ENOENT errors as CliUpdateError or classify them as "unknown" so
runUpdate cannot continue self-update work for an unreadable marker.
