Merge branch 'master' into NextHopRouter

* Add support for MeshLink

* Updated, enabled watchdog and added button definition

* added eink variant and removed some compile errors

* Small board json file edit

* Finally got trunk working (somehow?), this is just cleanup with trunk fmt

* Various improvements and cleanup. Removed the use of PIN_3V3_En and defined a specific WD_EN pin instead for better clarity. Will do a bit more testing asap to make sure everything still works as intended :)

* Enable on-board QSPI Flash

* run trunk fmt with clang-format

+# ClusterFuzzLite for Meshtastic
+
+This directory contains the fuzzer implementation for Meshtastic using the ClusterFuzzLite framework.
+See the [ClusterFuzzLite documentation](https://google.github.io/clusterfuzzlite/) for more details.
+
+## Running locally
+
+ClusterFuzzLite uses the OSS-Fuzz toolchain. To build the fuzzer manually, first grab a copy of OSS-Fuzz.
+
+```shell
+git clone https://github.com/google/oss-fuzz.git
+cd oss-fuzz
+```
+
+To build the fuzzer, run:
+
+```shell
+python3 infra/helper.py build_image --external $PATH_TO_MESHTASTIC_FIRMWARE_DIRECTORY
+python3 infra/helper.py build_fuzzers --external $PATH_TO_MESHTASTIC_FIRMWARE_DIRECTORY --sanitizer address
+```
+
+To run the fuzzer, run:
+
+```shell
+python3 infra/helper.py run_fuzzer --external --corpus-dir=<path-to-temp-corpus-dir> $PATH_TO_MESHTASTIC_FIRMWARE_DIRECTORY router_fuzzer
+```
+
+More background on these commands can be found in the
+[ClusterFuzzLite documentation](https://google.github.io/clusterfuzzlite/build-integration/#testing-locally).
+
+## router_fuzzer.cpp
+
+This fuzzer submits MeshPacket protos to the `Router::enqueueReceivedMessage` method. It takes the binary
+data from the fuzzer and decodes that data to a MeshPacket using nanopb. A few fields in
+the MeshPacket are modified by the fuzzer.
+
+- If the `to` field is 0, it will be replaced with the NodeID of the running node.
+- If the `from` field is 0, it will be replaced with the NodeID of the running node.
+- If the `id` field is 0, it will be replaced with an incrementing counter value.
+- If the `pki_encrypted` field is true, the `public_key` field will be populated with the first admin key.
+
+The `router_fuzzer_seed_corpus.py` file contains a list of MeshPackets. It is run from inside build.sh and
+writes the binary MeshPacket protos to files. These files are use used by the fuzzer as its initial seed data,
+helping the fuzzer to start off with a few known inputs.
+
+### Interpreting a fuzzer crash
+
+If the fuzzer crashes, it'll write the input bytes used for the test case to a file and notify about the
+location of that file. The contents of the file are a binary serialized MeshPacket protobuf. The following
+snippet of Python code can be used to parse the file into a human readable form.
+
+```python
+from meshtastic.protobuf import mesh_pb2
+
+mesh_pb2.MeshPacket.FromString(open("crash-XXXX-file", "rb").read())
+```
+
+Consider adding any such crash results to the `router_fuzzer_seed_corpus.py` file to ensure there a isn't
+a future regression for that crash test case.
