Avoid merging in channels due to implications in accuracy, performance,
and code complexity.

Here, I classify channels into three categories:
1. Channels whose requesters are CACHEs or PTWs.
2. Channels between O3_CPUs and their L1Is.
3. Channels between O3_CPU and their L1Ds.

Merging operations in categories 1 and 2 are unnecessary. For category
1, CACHEs or PTWs already merge requests with their MSHRs. For category
2, merging do not affect the simulation results because each request
consumes the fetch bandwidth even when it was merged with another.

Merging operations in category 3 do reduce the cycles consumed by memory
requests because LSQ do not implement merging and requests merged into
one only consumes one of the bandwidth. However, Intel® 64 and IA-32
Architectures Optimization Reference Manual: Volume 1 revision 050 and
the Software Optimization Guide for the AMD Zen5 Microarchitecture
revision 1.00 do not mention such merging though they discuss
store-to-load forwarding. An open source core, BOOMv3 does not implement
it either. Therefore, having such merging operations may not be
appropriate when accurately simulating conventional microarchitecture
designs.

Remove the merging operations in channel in hope that it will improve
accuracy for category 3 and performance for all categories. It also
reduces the code complexity of the channel implementation.

LSQ and MSHRs already implement forwarding so remove forwarding in
channel to reduce overheads and code complexity.

The occupancy of MSHRs is already tested with
test/cpp/src/402-miss-latency.cc and there is nothing special with
prefetch fills. This means we can safely remove the tests of MSHRs with
prefetch fills to save the code to maintain without hurting the ability
of the test suite to catch bugs.

"MSHR" stands for Miss Status Holding Register, but the word was too
overloaded:
- Writes that fill cache lines were also called MSHR.
- Cache misses that were merged to existing MSHRs or inflight fills
  before they get a MSHR allocated were also called MSHR.

Replace "MSHR" with "fill" or "miss" where appropriate.

Added test to the fix proposed by @gh1403.
This test ensures that re-references to the same page at the same level
does not result in the allocation of new pages, unexpected misses, or
inconsistent mappings.

A GENERATE statement was used to check a collection of 5 page numbers
instead of just 1, and each page may or may not be re-referenced 10
times following allocation to ensure the above behavior.

<li>Update README.md by <a

</ul>
<h2>v5.0.0</h2>
<h3>🚨 Breaking Change</h3>
<p>This release fixes an inconsistency in path behavior for single
artifact downloads by ID. <strong>If you're downloading single artifacts
by ID, the output path may change.</strong></p>
<h4>What Changed</h4>
<p>Previously, <strong>single artifact downloads</strong> behaved
differently depending on how you specified the artifact:</p>
<ul>
<li><strong>By name</strong>: <code>name: my-artifact</code> → extracted
to <code>path/</code> (direct)</li>
<li><strong>By ID</strong>: <code>artifact-ids: 12345</code> → extracted
to <code>path/my-artifact/</code> (nested)</li>
</ul>
<p>Now both methods are consistent:</p>
<ul>
<li><strong>By name</strong>: <code>name: my-artifact</code> → extracted
to <code>path/</code> (unchanged)</li>
<li><strong>By ID</strong>: <code>artifact-ids: 12345</code> → extracted
to <code>path/</code> (fixed - now direct)</li>
</ul>
<h4>Migration Guide</h4>
<h5>✅ No Action Needed If:</h5>
<ul>
<li>You download artifacts by <strong>name</strong></li>
<li>You download <strong>multiple</strong> artifacts by ID</li>
<li>You already use <code>merge-multiple: true</code> as a
workaround</li>
</ul>
<h5>⚠️ Action Required If:</h5>
<p>You download <strong>single artifacts by ID</strong> and your
workflows expect the nested directory structure.</p>
<p><strong>Before v5 (nested structure):</strong></p>
<pre lang="yaml"><code>- uses: actions/download-artifact@v4
  with:
    artifact-ids: 12345
    path: dist
# Files were in: dist/my-artifact/
</code></pre>
<blockquote>
<p>Where <code>my-artifact</code> is the name of the artifact you
previously uploaded</p>
</blockquote>
<p><strong>To maintain old behavior (if needed):</strong></p>
<pre lang="yaml"><code>&lt;/tr&gt;&lt;/table&gt; 
</code></pre>

This pr addresses issues identified by @aaarunan, adds testing, and
replaces the forward_list containers with regular vectors.

To facilitate testing, the build() function which was previously defined
in environment.cc had to be moved to environment.h.

Extension of PR from @Quangmire with the following improvements:
1. set sampling duel counter type (dscounter) added, which implements
the set sampling duel counter feature utilized by many replacement
policies and prefetchers
2. categorizer type, which implements the sampling utilized by 1 as a
categorizer, evenly splitting a given value into a sampled number of
categories (where 0 and 1 are used as indicators by the dscounter of
those sets to be sampled). How input values are translated to integers
to be sampled relies on a user-defined projection object.
3. static inlines of get_num_samples() and get_sample_rate() which when
provided a population? provides the recommended number of samples and
the corresponding sample rate.
4. The addition of a new msl/stat_methods.h header which includes 1, 2,
and 3 (and in the future could include other structures like this)
5. Tests for features introduced in 1, 2, and 3

<blockquote>
<h2>v8.0.0</h2>
<h2>v8 - What's new</h2>
<h3>Direct downloads</h3>
<p>To support direct uploads in <code>actions/upload-artifact</code>,
the action will no longer attempt to unzip all downloaded files.
Instead, the action checks the <code>Content-Type</code> header ahead of
unzipping and skips non-zipped files. Callers wishing to download a
zipped file as-is can also set the new <code>skip-decompress</code>
parameter to <code>false</code>.</p>
<h3>Enforced checks (breaking)</h3>
<p>A previous release introduced digest checks on the download. If a
download hash didn't match the expected hash from the server, the action
would log a warning. Callers can now configure the behavior on mismatch
with the <code>digest-mismatch</code> parameter. To be secure by
default, we are now defaulting the behavior to <code>error</code> which
will fail the workflow run.</p>
<h3>ESM</h3>
<p>To support new versions of the @actions/* packages, we've upgraded
the package to ESM.</p>

upgrading.</p>
</blockquote>
<h3>Node.js 24</h3>
<p>This release updates the runtime to Node.js 24. v6 had preliminary
support for Node 24, however this action was by default still running on
Node.js 20. Now this action by default will run on Node.js 24.</p>

<h2>v7.0.0</h2>
<h2>v7 What's new</h2>
<h3>Direct Uploads</h3>
<p>Adds support for uploading single files directly (unzipped). Callers
can set the new <code>archive</code> parameter to <code>false</code> to
skip zipping the file during upload. Right now, we only support single
files. The action will fail if the glob passed resolves to multiple
files. The <code>name</code> parameter is also ignored with this
setting. Instead, the name of the artifact will be the name of the
uploaded file.</p>

The previous implementation of the sampler-set tag check mechanism was
convoluted, and would result in false matches / false mismatches under
some cache configurations.

This pr simplifies the check to the block number, functionally
equivalent to what should have been implemented but far simpler and
avoids any confusion or potential bugs by introducing additional slicing
to remove variable amounts of set index and sampler index bits.

A test was added to ensure the matcher was behaving properly.

Fixes issue raised in #697

Make `dib_inorder_width` and `dib_hit_buffer_size` configurable with the
config.json.

I was trying to configure champsim to get an unrealistically high IPC
just to confirm that there aren't missing pieces in my understanding of
how everything works and found I couldn't make IPC above 5. I believe
the culprit is these configuration values being hard-coded.

catch2 dependency includes should be angle brackets, not double quotes -
otherwise you will get errors such as the following

only a few test files had quotes, most already have angle brackets

```bash
champsim> g++ @global.options @absolute.options -MM -MT .csconfig/test/602-walk-latency.d -MT .csconfig/test/602-walk-latency.o -I.csconfig -MF .csconfig/test/602-walk-latency.d test/cpp/src/602-walk-latency.cc
champsim> test/cpp/src/602-walk-latency.cc:1:10: fatal error: catch.hpp: No such file or directory
champsim>     1 | #include "catch.hpp"
champsim>
```

ran clang format to sort the imports
