doc: develop: add documentation for tracing
ci: build-native: publish tt-console and tt-tracing artifacts

make -C scripts/tooling
. Now they are built on every commit.
ci: release: ensure build artifacts for all board revisions are in zip
scripts: tt_boot_fs: ls: add hexdump functionality when verbose >= 2
this allows us to inspect all contents of TT Boot FS .bin files without breaking out a separate hex editor

a common location for custom Tenstorrent shell commands
print telemetry data with
telem
sub-commandread (and write) asic state with
asic_state
sub-command
app: dmc: enable logging via DMC SMBUS path
first logs to a local ringbuffer, and then data is sent over smbus from DMC to SMC
users should now be able to view DMC logs with
tt-console -c 2
Driversο
drivers: sensor: pvt: integrate pvt driver, add tolerance in tests, read efused temperature calibration
drivers: smbus: add platform-independent
zephyr,smbus-target
driver (should be upstreamed shortly)
