sdk: guard Reticulum preview push boundary

- add source-boundary coverage for canonical Reticulum preview endpoint identity
- require sync push to retain explicit Reticulum preview handling
- require SDK errors to retain unavailable and deferred Reticulum codes
- validate with fmt, sdk check, source-boundary tests, and xtask check
