v2.6.0

AntHocNet v2.6.0. Release notes: https://danieljoppi.github.io/AntHocNet/docs/releases/v2.6.0/
(from CHANGELOG.md; the site redeploys when this run finishes).

Install bundle (anthocnet-2.6.0.zip) — the source to
drop onto your own simulator tree:
make doctor NS3DIR=… then make install-ns3 NS3DIR=…
(BASELINES=0 for AntHocNet alone).

Drop-in ns-3 modules (anthocnet-ns3-modules-2.6.0.tar.gz):
no checkout needed, tar -xzf anthocnet-ns3-modules-2.6.0.tar.gz -C /path/to/ns-3/contrib,
then configure and build ns-3. The same files are on the generated
ns3-module branch. SHA-256: fa852947148a4b538f4181616132cf99356f4314c9652ce14e94aaf6bafc3ec3.
With bake (ns-3's installer): copy anthocnet-2.6.0.bakeconf.xml
into your bake checkout's contrib/, then
./bake.py configure -e ns-3.42 -e anthocnet && ./bake.py download && ./bake.py build.

Pre-built simulator images are on GHCR (see docker/README.md),
including release-pinned tags anthocnet-ns3:<sim-version>-v2.6.0.

Verify your download. The SHA-256 digest is published twice — in
this body and as the anthocnet-2.6.0.zip.sha256 asset:

353eb772c1559aa42d6c2f6646414b37769d5ea51d7390d0e1acb2cf14686e3f  anthocnet-2.6.0.zip

sha256sum -c anthocnet-2.6.0.zip.sha256   # both files in the same directory

Verify where it came from. Both downloads carry signed SLSA
build provenance, and the bundle an SPDX SBOM
(anthocnet-2.6.0.spdx.json). With the GitHub CLI:

gh attestation verify anthocnet-2.6.0.zip --repo danieljoppi/AntHocNet

The images are signed with cosign (keyless). See
SECURITY.md.
