75929b11ed doc: add release note for submitSolution IPC changes (woltx)
ed75d70fdb refactor: centralize SubmitBlock result handling (w0xlt)
cbaa1696f3 mining: add reason and debug output to submitSolution (w0xlt)
83f3bc002d mining: clarify SubmitBlock result handling (w0xlt)

Pull request description:

  `BlockTemplate.submitSolution` currently returns only a boolean, so IPC mining clients cannot determine why a submission failed without inspecting Bitcoin Core's debug log.

  Returning `reason` and `debug`, as `Mining.submitBlock` already does, lets callers distinguish a concrete block rejection from a duplicate or inconclusive result. Here, `inconclusive` means the method returns failure, but validation did not determine that the submitted block is invalid.

  This follow-up was suggested during the review of #34644:
  https://github.com/bitcoin/bitcoin/pull/34644#discussion_r2853758006

  This PR:

  - Extracts a shared `SubmitBlock` helper that wraps `ProcessNewBlock` with `SubmitBlockStateCatcher` to capture `BlockValidationState`
  - Adds `reason` and `debug` output parameters to `submitSolution`, matching `submitBlock`
  - Makes both methods delegate to the same helper, eliminating duplicated logic

src/node/

The src/node/ directory contains code that needs to access node state (state in CChain, CBlockIndex, CCoinsView, CTxMemPool, and similar classes).

Code in src/node/ is meant to be segregated from code in src/wallet/ and src/qt/, to ensure wallet and GUI code changes don't interfere with node operation, to allow wallet and GUI code to run in separate processes, and to perhaps eventually allow wallet and GUI code to be maintained in separate source repositories.

As a rule of thumb, code in one of the src/node/, src/wallet/, or src/qt/ directories should avoid calling code in the other directories directly, and only invoke it indirectly through the more limited src/interfaces/ classes.

This directory is at the moment sparsely populated. Eventually more substantial files like src/validation.cpp and src/txmempool.cpp might be moved there.
