Update shared documentation publisher

[tony]

Pin only the shared port builder and publisher to 9f5cef954e3c52e7eb239a3da56a34f92b69f161 from 8f304904465a15b929e139345d9b9e4672ecb7b3. All other workflow bytes, library contents, triggers, permissions and language/source/version inputs remain unchanged.

The shared checkpoint links qualified Rust I/O errors to the standard-library reference. Its exact required CI and root merge receipts must be verified before this operator runs. This PR does not claim an owner build or publication pass. Root reviews this exact caller diff, actual repository-required checks and reviews before merge; optional native estate checks are not a new universal gate.

Execution route: exact_source_manual_dispatch_after_root_controlled_pin_merge. Root separately schedules reviewed merges and exact source requests from the actual workflow state. Julia/Rust/.NET use their genuine new pin-merge push. If the current active workflow already publishes the intended source on merge, retain that actual event and do not issue a duplicate request. Future source/native/run identities will be bound to actual events.
