docs: update daemon CLI syntax from flags to subcommands

Update all documentation to use the new subcommand syntax:
- `bd daemon --start` → `bd daemon start`
- `bd daemon --stop` → `bd daemon stop`
- `bd daemon --status` → `bd daemon status`
- `bd daemon --health` → `bd daemon status --all`
- `--global=false` → `--local`

The old flag syntax is deprecated but still works with warnings.

Closes: bd-734vd
