signals: remove boost::signals2 from depends and vcpkg
What changed, and why it matters
This commit simply removes an unused software component (Boost.Signals2) from two dependency lists used to build Bitcoin Core. It is a cleanup change, not a security fix.
No security action required. Treat as routine dependency cleanup.
Security signals we found
No strong security signals were identified.
Evidence from the diff
The patch removes ‘signals2’ from the Boost include libraries in depends/packages/boost.mk and deletes the ‘boost-signals2’ entry from vcpkg.json. This indicates Bitcoin Core no longer depends on Boost.Signals2. There is no code change to Bitcoin Core itself and no indication of a vulnerability in either the removed library or the project.
