Async cwd validation dedupes by exact path but had no concurrency bound, and a dead UNC share answers `stat` in ~21s while holding one of libuv's 4 default fs threads. Four distinct paths on one unreachable server therefore starved every other async fs read in the daemon — including the cold-restore history replay running alongside them — which moves the head-of-line stall #14848 removed from the event loop into the thread pool. Adds a per-route lane of 2, reusing PrioritySemaphore and matching the per-distro lane in rate-limits/auth-filesystem-operation.ts. Keyed by the host that has to answer (WSL distro, or the `\\server` prefix) so many dead subdirectories of one share fold into one lane. Local-disk paths bypass the lane entirely: a global cap would queue a healthy local spawn behind a dead share. Moves PrioritySemaphore to src/shared. It has no imports, and reaching into src/main/daemon from src/main/providers inverted the dependency direction that already runs daemon -> providers. Note this bounds pool occupancy, which cancellation cannot: an aborted `stat` still holds its libuv thread until the OS returns. STA-4543
