- Around line 1010-1012: Update the live reload path using Config::read_sources
to retain and report unknown keys instead of discarding them as _unknown_keys.
Track reported keys so reload warnings include newly observed keys only and do
not repeat keys already reported.

Report unknown keys during live reload.
If an operator misspells runner.log_exit_status_rules during a live edit, deserialization can leave the rule list at its empty default. The reload then applies that empty list without a warning.
Track and report newly observed unknown keys during reload. Avoid repeating warnings for keys already reported. This is a minor issue, not a major regression: the previous implementation also handled unknown keys silently during reload.

The
override_real_valuessettings in #2531 had no effect because RQD never read them. The block was underrunner:instead ofmachine:, and two fields had the wrong names (memory→memory_size,desktop_mode→workstation_mode). RQD drops unknown keys without saying anything, so nothing pointed at the mistake. The snippet was copied from the commented example inrust/config/rqd.dummy.cuebot.yaml/rqd.local.cuebot.yaml, which had the same errors. The override code itself works once the keys are in the right place.WARN Config::load: ignoring unrecognized config key "runner.override_real_values". This usesserde_ignored(the crate Cargo uses for its "unused manifest key" warning)."": ""placeholders inrqd.yamlare not flagged.machine:with the correct field names.
