Fix container sync races that leaked orphan blobs; add a system-prune CLI command

Browse Source 
sync_workspace (user-triggered) and the reconciler's sync_bidirectional_sync
could run concurrently for the same project, and store_upload's read-then-
write on a changed path meant two racing imports each wrote their own blob
while only one ever got referenced - the loser leaked forever. Combined with
no build-artifact exclusion, an actively-compiling workspace hit this
constantly and leaked 5.9M orphan blobs (~96GB) in production before it was
caught.

Closes it at the root: api._sync_dir_bidirectional_locked serializes both
call sites per-project (non-blocking - a project already mid-sync is simply
skipped until the next tick), and IMPORT_SKIP_NAMES/IMPORT_SKIP_EXTENSIONS
keep build output (build/, dist/, *.o, *.pyc, ...) out of the walk entirely.

Recovering what already leaked is a separate concern: a new CLI subcommand
(plus matching make targets) sweeps soft-deleted attachment/project-file
blobs and any blob with zero DB reference at all, plus orphaned container
workspace directories. run_maintenance_cleanup.sh wraps the existing
prune/clear commands for routine disk upkeep.
