Release 0.35.0

[mobileoverlord]

Summary

Bump avocado-cli from 0.34.0 to 0.35.0.

Features

• btrfs subvolumes: add subvolume config for var partitions with per-extension and runtime-level options (compression, quotas, nodatacow, rw/ro), with conflict detection, rebuild-hash integration, and per-property echo during post-creation setup (#085af83, #234be34)
• avocado connect clean: new command to clean up connect state (#2964d8d)
• SDK version locking per host arch: remove the strip_arch workaround so full NEVRA versions are stored in the SDK lock file, giving exact package pinning per host architecture (#085af83)

Fixes

• subvolumes are created rw at mkfs time and flipped to ro after properties are set, since read-only subvolumes reject btrfs property set (#e2dbb1d)
• skip compression on nodatacow subvolumes — NOCOW and compression are mutually exclusive on btrfs (#2c5b944)
• replace unsupported mkfs.btrfs --inode-flags with --compress + post-creation loop mount (chattr +C for nodatacow, per-subvolume properties via loop mount) (#2eb039d)

Other

• init --reference now pulls from the standalone avocado-linux/references repo instead of avocado-linux/avocado-os/references/ (#b41a013)
• formatting / rustfmt cleanup (#934d86e, #1534672)

Test plan

• Verify avocado --version reports 0.35.0
• CI passes
• avocado connect clean works as expected
• Runtime build with btrfs subvolume config (compression, nodatacow, ro) produces a valid image
• avocado init --reference <name> resolves against the standalone references repo
