v0.10.0

Added

• aisync completion <bash|zsh|fish> command emits a shell completion script to stdout. Covers all commands, subcommands, flags, and dynamic provider names sourced from the registry.

Changed

• Breaking: aisync watch is now bidirectional. Changes in any participating worktree propagate to all others, not just from a single source. Participants are discovered from aisync-lock.json files; the sync mode is inherited from the first lock found.
• Breaking: removed the -l/--link flag from aisync watch. Mode is now read from existing locks; mixing modes across siblings is not supported within a single watch session.

Fixed

• copy and link path arguments now expand environment variable names before resolving paths.
