`cache_sizes` is no longer used and can be removed from `CompleteChainstateInitialization()`

How about a comment here to document the non-trivial things this does (creating blockman, opening blocksdb, cleaning up old block files in case of pruning) and doesn't (opening coins db)? I think this would help understanding the sequence better.

Calling `RegisterPeer` with the same `peer_id` multiple times will result in `ReconciliationRegisterResult::ALREADY_REGISTERED`.

The docs of both `PreRegisterPeer` and `RegisterPeer` specify that they should called only once.

On NetBSD, with newer Python versions 3.12.8 and 3.13.1, many functional tests fail due to `float` numbers internal representation.

The typical error looks as follows:

It would be good to explain this a bit better and provide a `--tracerpc` log, or similar.

looking good, only left few nits. No need to tackle them. Will test it properly in the coming days.

Code review 7f34802fd726b259f7df6f605e1d488faf251127. I got pretty lost here and only reviewed about half of it so far, but overall I think the changes look good and make a lot of sense.

I left some suggestions below which I think could make code clearer, but they are not important so feel free to ignore any you disagree with.

In commit "Add DeriveTarget() to pow.h" (2f549b547207839ab666ac2b8b02811ff0990214)

I don't really like the approach here of duplicating the `CheckProofOfWorkImpl` code and having a comment saying a future refactor could deduplicate it. I think it could avoid confusion and bugs later on to just split the `CheckProofOfWorkImpl` function into two parts now in a way that makes it obvious behavior is not changing. Would suggest:

In commit "rpc: gettarget" (0c56689e425684c0c5b2058c1a47f293ac7032e6)

It's not right to involve the `ser_uint256` function here, since converting the target `int` to a string should not involve bitcoin serialization. This can just use python string formatting `return f"{target:064x}"`

In commit "test: add nBits coverage" (ecb18b3405e4a61f872d03f667c167fb7c4a52cf)

I think it would be good to make this more descriptive. Maybe add "Compact representation of the block difficulty target, which the block hash interpreted as a little-endian number must not be greater than. This is hexadecimal string containing 32-bit number with the compact representation described in the arith_uint256 class of the difficulty target."

`return f"{nbits:08x}"` would be a more direct conversion from number to string and would make the python code more consistent with the c++ code.

(https://github.com/bitcoin/bitcoin/pull/31596)
This is a documentation-only change following up on suggestions made in the #30526 review.

Motivation for this change is that I was recently reviewing #31583, which reminded me how confusing the arithmetic blob code was and made me want to write better comments.
