The next commit requires an additional mainnet block which changes the difficulty.
Also fix a few minor mistakes in the test (suite):
- rename the create_coinbase retarger_period argument to halving_period. Before bitcoin#31583 this was hardcoded for regtest where these values are the same.
- drop unused fees argument from mine helper
Finally the CPU miner instructions for generating the alternative mainnet chain are expanded.

`bitcoin-wallet` as-is is merely an offline wallet inspection tool
(introduced more than 9 years ago in PR #13926) that doesn't have any
relation with IPC/multiprocess, so remove it from the list of binaries
that use `libbitcoin_ipc`.

Oversized allocations can cause out-of-memory errors or [heavy swapping](https://github.com/getumbrel/umbrel-os/issues/64#issuecomment-663637321), [grinding the system to a halt](https://x.com/murchandamus/status/1964432335849607224).
`LogOversizedDbCache()` now emits a startup warning if the configured `-dbcache` exceeds a cap derived from system RAM, using the same parsing/clamping as cache sizing via CalculateDbCacheBytes(). This isn't meant as a recommended setting, rather a likely upper limit.
Note that we're not modifying the set value, just issuing a warning.
Also note that the 75% calculation is rounded for the last two numbers since we have to divide first before multiplying, otherwise we wouldn't stay inside size_t on 32-bit systems - and this was simpler than casting back and forth.
We could have chosen the remaining free memory for the warning (e.g. warn if free memory is less than 1 GiB), but this is just a heuristic, we assumed that on systems with a lot of memory, other processes are also running, while memory constrained ones run only Core.
If total RAM < 2 GiB, cap is `DEFAULT_DB_CACHE` (`450 MiB`), otherwise it's 75% of total RAM.
The threshold is chosen to be close to values commonly used in [raspiblitz](https://github.com/raspiblitz/raspiblitz/blob/dev/home.admin/_provision.setup.sh#L98-L115) for common setups:
| Total RAM | `dbcache` (MiB) | raspiblitz % | proposed cap (MiB) |
|----------:|----------------:|-------------:|-------------------:|
| 1 GiB | 512 | 50.0% | 450* |
| 2 GiB | 1536 | 75.0% | 1536 |
| 4 GiB | 2560 | 62.5% | 3072 |
| 8 GiB | 4096 | 50.0% | 6144 |
| 16 GiB | 4096 | 25.0% | 12288 |
| 32 GiB | 4096 | 12.5% | 24576 |
[Umbrel issues](https://github.com/getumbrel/umbrel-os/issues/64#issuecomment-663816367) also mention 75% being the upper limit.
Starting `bitcoind` on an 8 GiB rpi4b with a dbcache of 7 GiB:
> ./build/bin/bitcoind -dbcache=7000
warns now as follows:
```
2025-09-07T17:24:29Z [warning] A 7000 MiB dbcache may be too large for a system memory of only 7800 MiB.
2025-09-07T17:24:29Z Cache configuration:
2025-09-07T17:24:29Z * Using 2.0 MiB for block index database
2025-09-07T17:24:29Z * Using 8.0 MiB for chain state database
2025-09-07T17:24:29Z * Using 6990.0 MiB for in-memory UTXO set (plus up to 286.1 MiB of unused mempool space)
```
Besides the [godbolt](https://godbolt.org/z/EPsaE3xTj) reproducers for the new total memory method, we also tested the warnings manually on:
- [x] Apple M4 Max, macOS 15.6.1
- [x] Intel Core i9-9900K, Ubuntu 24.04.2 LTS
- [x] Raspberry Pi 4 Model B, Armbian Linux 6.12.22-current-bcm2711
- [x] Intel Xeon x64, Windows 11 Home Version 24H2, OS Build 26100.4351

Added a minimal system helper to query total physical RAM on [Linux/macOS/Windows](https://stackoverflow.com/a/2513561) (on other platforms we just return an empty optional).
The added test checks if the value is roughly correct by checking if the CI platforms are returning any value and if the value is at least 1 GiB and not more than 10 TiB.
The max value is only validated on 64 bits, since it's not unreasonable for 32 bits to have max memory, but on 64 bits it's likely an error.
https://learn.microsoft.com/en-us/windows/win32/api/sysinfoapi/ns-sysinfoapi-memorystatusex
> ullTotalPhys The amount of actual physical memory, in bytes.
https://man7.org/linux/man-pages/man3/sysconf.3.html:
> _SC_PHYS_PAGES The number of pages of physical memory. Note that it is possible for the product of this value and the value of _SC_PAGESIZE to overflow.
> _SC_PAGESIZE Size of a page in bytes. Must not be less than 1.

Prior releases installed using these paths. Especially annoying was that the lingering registry entry for the uninstaller would show up as "Bitcoin Core (64-bit)" besides the current "Bitcoin Core" entry in the list of installed programs, and whichever was uninstalled last would fail to work as they would default to the same install directory.

In the presence of smaller transactions on the network, blocks can sustain a
higher relay rate than 7tx/second. In this event, the per-peer inventory queues
can grow too large.
This commit bumps the rate up to 14 tx/s (for inbound peers), increasing the
safety margin by a factor of 2.
Outbound peers continue to receive relayed transactions at 2.5x the rate of
inbound peers, for a rate of 35tx/second.

m_cached_from_me is used to track whether a transaction is "from me", i.e. has
any inputs which belong to the wallet. This is held in memory only in
the same way that a transaction's balances are.

Instead of checking whether the total amount of inputs known by the
wallet is greater than 0, we should be checking for whether the input is
known by the wallet. This enables us to determine whether a transaction
spends an of output with an amount of 0, which is necessary for marking
0-value dust outputs as spent.

If something is imported into the wallet, it can change the 'from me'

gettransaction's "fee" field which is only shown for transactions that

fa8f081af31cd99155c7545643e7b10beb26714d ci: Checkout latest merged pulls (MarcoFalke)
Pull request description:
Currently, the `actions/checkout@v5` checks out pull requests merged against master, which is what we want.
However, it checks out ancient/stale merge commits on a re-run. This is documented (https://docs.github.com/en/actions/how-tos/manage-workflow-runs/re-run-workflows-and-jobs):
> Re-run workflows [...] will also use the same GITHUB_SHA (commit SHA) and GITHUB_REF (git ref) of the original event that triggered the workflow run.
For example:
* https://github.com/bitcoin/bitcoin/actions/runs/17458152407/job/49579638898?pr=29641#step:9:914 compiles with IPC=ON, even though latest master is at ed2ff3c63d83e275b0785a695fa4db38870abf1a
* https://github.com/bitcoin/bitcoin/pull/32989#issuecomment-3133536724 (example explained in comment)
This is problematic, because:
* Unrelated CI failures and intermittent issues, which are fixed or worked around in latest master can not be cleaned by re-running the task. The author has to actively go out and (force-)push the branch, invalidating review.
* It is odd to have a recent CI run, but it uses code and config from the past.
* Detecting silent merge conflicts by re-running the CI task is impossible.
Fix all issues by checking out the latest merged state of the pull request. The behavior is unchanged for non-pull-request actions. This patch changes the "re-run" default behaviour. Forcing it to use the new state instead of running the old state again.

790b440197bde322432a5bab161f1869b667e681 Fix benchmark CSV output (Hennadii Stepanov)
Pull request description:
The `SHA256AutoDetect` return output is used, among other use cases, to name benchmarks. Using a comma breaks the `bench_bitcoin` CSV output.
This PR replaces the comma with a semicolon, which fixes https://github.com/bitcoin/bitcoin/issues/33331.

5e585a0fc4fd68dd7b4982054b34deae2e7aeb89 net: check for empty header before calling FillBlock (Eugene Siegel)
Pull request description:
This avoids an Assume crash if multiple blocktxn messages are received. The first call to `FillBlock` would make the header empty via `SetNull` and the call right before the second `FillBlock` would crash [here](689a321976/src/net_processing.cpp (L3333)) since `LookupBlockIndex` won't find anything. Fix that by checking for an empty header before the Assume.

Pull request description:
Closes https://github.com/bitcoin/bitcoin/issues/26362
This continues the work that was started with #26426. It fixes the overflow issue by switching the tracked values that are in danger of overflowing from `CAmount` to `arith_uint256`.
The current approach opts for a simple solution to ensure compatibility with datadirs including the previous version of the index: The new version of the index goes into a separate location in the datadir (`index/coinstatsindex/` rather than `index/coinstats/` before, the new naming is more consistent with the naming of the other indexes). There is no explicit concept of versioning of the index which earlier versions of this PR had. Having the two different versions of the index in separate places allows for downgrading of the node without having to rebuild the index. However, there will be a warning printed in the logs if the new code (v30) detects the old index still being present. A future version could delete a left-over legacy index automatically.
The PR also includes several minor improvements but most notably it lets new entries be calculated and stored without needing to read any DB records.
