* Bound HTTP request timeouts and retry budget
With no request timeout, Retry(total=30, backoff_factor=2,
backoff_max=60) let a single unreachable server hang the client for
around 26 minutes: backoff sleeps alone sum to that, and each of the
30 connection attempts could itself stall indefinitely without a
timeout. Measured a black-holed connect attempt taking 75s on this
machine with no timeout set, confirming the mechanism.
- Add HTTP_TIMEOUT (connect, read) and a tighter retry budget
(HTTP_RETRY_TOTAL/BACKOFF_FACTOR/BACKOFF_MAX) in dsc/const.py,
bounding the worst case to a few minutes.
- Pass timeout=HTTP_TIMEOUT on both SeafileClient HTTP calls (token
fetch, remote library listing).
- Add NetworkError(DscError) so a network failure is caught by
start.py's existing top-level DscError handling instead of
producing a bare traceback.
- Add tests/test_http.py covering the retry policy values, timeout
propagation, and error wrapping.
- Check off the corresponding IMPROVEMENTS.md items.
* Include URL and status code in NetworkError messages
Copilot review on PR #28 flagged that the non-200 path for remote
library listing raised NetworkError with only the raw response body,
losing which request failed and its status code. The token-fetch
error had the same gap. Both now include the URL and HTTP status.

start_daemon and stop_daemon polled "while True" with no bound, and no
seaf-cli exit code was checked. A daemon that failed to start left the
container spinning forever with nothing pointing at the cause, and there was
no signal handling, so "docker stop" waited the full 10 second grace period
and then SIGKILLed the process with the daemon still running.
Readiness polling is now bounded by DAEMON_START_TIMEOUT and
DAEMON_STOP_TIMEOUT. The stop timeout is 8 seconds so a graceful shutdown
fits inside the docker stop grace period, and a test asserts that relation.
SIGTERM and SIGINT raise GracefulShutdown, and the lifecycle moved into
start.run(), which always stops the daemon on the way out and returns the
process exit code: 0 on a clean finish or a stop signal, 1 on a daemon or
configuration failure.
seaf-cli exit codes are checked. A failed sync is reported per library and
does not stop the remaining libraries, since one bad library should not take
the container down.
Verified in the built image: "docker stop" now returns in 0s with exit code 0
and the daemon stopped, against 10s and exit 137 before. A daemon that cannot
start exits 1 with the failing command and its exit code in the log.
Also bumps actions/setup-python to v7, which clears the last Node 20
deprecation warning; v7 only drops the unused pip-install input.
