Now that ancestor calculation never fails (due to ancestor/descendant limits
being eliminated), we can eliminate the error handling from
CalculateMemPoolAncestors.
With the descendant size limits removed, replace the concept of "max number of
descendants of any ancestor of a given tx" with the cluster count of the cluster
that the transaction belongs to.
The mempool clusters and linearization permit sorting the mempool topologically
without making use of ancestor counts (as long as the graph is not oversized).

Previously, transaction batches were first sorted by ancestor count and then
feerate, to ensure transactions are announced in a topologically valid order,
while prioritizing higher feerate transactions. Ancestor count is a crude
topological sort criteria, so replace this with linearization order so that the
highest feerate transactions (as would be observed by the mining algorithm) are
relayed before lower feerate ones, in a topologically valid way.
This also fixes a test that only worked due to the ancestor-count-based sort
order.
With a total ordering on mempool transactions, we are now able to calculate a
transaction's mining score at all times. Use this to improve the RBF logic:
- we no longer enforce a "no new unconfirmed parents" rule
- we now require that the mempool's feerate diagram must improve in order
to accept a replacement
- the topology restrictions for conflicts in the package rbf setting have been
eliminated
Revert the temporary change to mempool_ephemeral_dust.py that were previously
made due to RBF validation checks being reordered.

The addition of a cluster size limit makes the CPFP carveout rule useless,
because carveout cannot be used to bypass the cluster size limit. Remove this
policy rule and update tests to no longer rely on the behavior.
After cluster mempool, the mini_miner will no longer match the miner's block
construction. Eventually mini_miner should be reworked to directly use
linearizations done in the mempool.
Rather than evicting the transactions with the lowest descendant feerate,
instead evict transactions that have the lowest chunk feerate.
Once mining is implemented based on choosing transactions with highest chunk
feerate (see next commit), mining and eviction will be opposites, so that we
will evict the transactions that would be mined last.
Include an adjustment to mempool_tests.cpp due to the additional memory used by
txgraph.
Includes a temporary change to the mempool_ephemeral_dust.py functional test,
due to validation checks being reordered. This change will revert once the RBF
rules are changed in a later commit.

Pull request description:
The local_socket_bytes variable was never used. Removed it to clean up dead code.

0aebdac95da9a7d476264424c0107bd806ce5362 init: completely remove `-maxorphantx` option (Sebastian Falbesoner)
Pull request description:
This is a small follow-up for #32941 (commit 1384dbaf6d0bfcdb05f97e1e3cb3d5e498bee505), removing the `-maxorphantx` option completely, now that v30 has been released. If removing it for v31 is seen as controversial/premature (I personally don't think it is), the merge can be delayed for a future release.

Pull request description:
The unserialization flows of the PSBT types work based on few underlying assumptions of functions from `serialize.h` & `stream.h` that takes some to understand when read the first time.
Add few comments that highlight these assumptions hopefully making it easier to grasp. Also, mention key/value format types as per BIP 174.

Moving the python code out of the yaml string makes it easier to lint,

Pull request description:
This contains a few follow-ups to https://github.com/bitcoin/bitcoin/pull/33744:
* Rewrite the actions Bash snippet to Python. I've confirmed it still works in https://github.com/maflcko/bitcoin-core-with-ci/actions/runs/19067932430 (scroll down).
* Add a lint-build retry to avoid issues such as https://github.com/bitcoin/bitcoin/issues/33640 for the lint task as well.
* Finally, run the `debug_pull_request_number_str` annotation on all checks, to ensure they are present even when GitHub deletes annotations on a re-run. For example, the initial attempt https://github.com/bitcoin/bitcoin/actions/runs/19041534107/attempts/1?pr=33772 has the annotations, and the lint re-run has them removed: https://github.com/bitcoin/bitcoin/actions/runs/19041534107?pr=33772
