AX fixes: --json on all commands, exit codes, channel resolution, init
CLI spec:
- AX conventions table: --json, --quiet, exit codes, pipeable, stderr
- colony init command for .colony.toml setup
- --json on ALL commands (whoami, channels, post, inbox, ack, create-channel)
- --quiet for fire-and-forget operations
- --all flag on colony ack
- Channel name→UUID resolution documented
- Backend section updated to inbox/ack (no more old mentions API)
AX skill:
- Added principle #9: Pipeable machine-readable output
