2b00030af8interfaces, chain, refactor: Remove inaccurate getActiveChainLocator (pablomartin4btc)110a0f405cinterfaces, chain, refactor: Remove unused getTipLocator (pablomartin4btc) Pull request description: Remove `Chain::getTipLocator`, `Chain::GetLocator()`, and `Chain::getActiveChainLocator`: - `Chain::getTipLocator` is no longer used. - `Chain::GetLocator`, replaced its call by `GetLocator()`, which uses `LocatorEntries`, avoiding direct access to the chain itself (change suggested by l0rinc while reviewing this PR to maintain consistency with the overall refactoring). - `Chain::getActiveChainLocator`, whose name was misleading, has functionality redundant with Chain::findBlock. - Additionally, the comment for getActiveChainLocator became inaccurate following changes in commited470940cd(from PR #25717). This is a [follow-up](https://github.com/bitcoin/bitcoin/pull/29652#issuecomment-3151665095) to #29652.

Internal c++ interfaces
The following interfaces are defined here:
-
Chain— used by wallet to access blockchain and mempool state. Added in #14437, #14711, #15288, and #10973. -
ChainClient— used by node to start & stopChainclients. Added in #14437. -
Node— used by GUI to start & stop bitcoin node. Added in #10244. -
Handler— returned byhandleEventmethods on interfaces above and used to manage lifetimes of event handlers. -
Init— used by multiprocess code to access interfaces above on startup. Added in #19160. -
Ipc— used by multiprocess code to accessInitinterface across processes. Added in #19160.
The interfaces above define boundaries between major components of bitcoin code (node, wallet, and gui), making it possible for them to run in different processes, and be tested, developed, and understood independently. These interfaces are not currently designed to be stable or to be used externally.
