Description

Fixes #2419.

beet update -m used to stop on the first file it couldn't move, so everything after it was left half-updated in the DB (album record still had the old name, files not moved). Now a FilesystemError during a move gets logged and the update keeps going with the rest, like suggested in the issue.

• Album loop: if moving an album fails, the error is logged and it moves on to the next album.
• Item loop: if moving an item fails, the error is logged and the item is skipped without storing it. That way its mtime isn't updated, so the next update picks it up again and retries. Same pattern as the existing ReadError handling right above it.
• Only FilesystemError is caught, so anything else still surfaces.

Added two regression tests, one for albums and one for singletons. Both fail without the fix and pass with it. Left beet move (#1926) out of this PR to keep it small, happy to look at it on its own.

AI disclosure: I used Claude Code to help write the code, tests and changelog entry. I reproduced the bug on current master, decided the approach and scope (following the discussion in the issue), had the fix extended to the item loop after reviewing the first version, and verified everything with the tests and the repro. Happy to explain or rework any part of it.
