* master: read the writable-volumes cap from master.toml -maxWritableVolumes becomes the master.max_writable_volumes config key, so the new master limit is set the same way as other master options instead of a flag wired into every command that embeds a master. * master: name the writable cap master.max_writable_volumes_per_layout The cap applies per volume layout (collection + replica placement + ttl + disk type), so the key names its scope instead of reading as a global cap. * master: keep an embedder's MaxWritableVolumes when the key is unset NewMasterServer overwrote option.MaxWritableVolumes with the viper value, which reads as 0 whenever master.toml omits the key, silently dropping a cap a Go caller supplied through MasterOption. Seed the default from the option instead so the field survives an absent key; an explicit config entry still wins. * master: drop stray nested-checkout gitlinks Generated with [Devin](https://devin.ai) Co-Authored-By: Devin <158243242+devin-ai-integration[bot]@users.noreply.github.com> --------- Co-authored-by: Devin <158243242+devin-ai-integration[bot]@users.noreply.github.com>
