Phase-1 low-risk batch, each rebased onto fresh master + gated fresh:
- #3883 (@rodboev, #3740): sidebar refreshes a stale message_count:0 index row
from its sidecar when user_message_count>0 + sidecar mtime newer than index,
self-healing the interrupted-stream stale-count case beyond compression lineage.
- #3878 (@rodboev, #3833): manual workspace refresh clears the dir cache and
re-fetches expanded descendants so background-written files become visible.
- #3880 (@koshikai): translate the 11 remaining English strings in the ja locale.
greptile flags evaluated: #3878 P1 relative-path + P2 stale-comment already fixed
in PR head; #3883 P2 missing-snapshot-test already covered by the PR's own
test_all_sessions_refreshes_stale_zero_count_snapshot_row_from_sidecar, P2
double-stat is a bounded cheap micro-opt (FOLD); #3880 'needs screenshots'
rejected (in-place translation of existing keys, no UI shape change).
