ISequence::nextId() takes the server id, the seconds and the milliseconds, but the generator passed the seconds, the milliseconds and the server id, so the sequences were keyed on the wrong values. Assisted-by: ClaudeCode:claude-opus-5-5 Signed-off-by: Carl Schwan <carl@carlschwan.eu>

Store one slot per second of the TTL window and per millisecond in each lock file, so generating an id only reads and writes 8 bytes instead of decoding, filtering and rewriting a JSON map of the last 30 seconds. The fsync is not needed as the files only coordinate processes running at the same time. Generating an id went from 660µs to 22µs with the temporary directory on disk, and from 24µs to 11µs on tmpfs.

This allow to simplify a bit the code, also add a small description of the algorithm. Assisted-by: ClaudeCode:claude-opus-5-5 Signed-off-by: Carl Schwan <carl@carlschwan.eu>
