toolchain_tool carries the bin/xtensa-lx106-elf-<name> pattern and the
Windows suffix that four call sites previously spelled out (only one of
which handled the suffix). ccache_env and get_build_env accept the
already-resolved ccache path so run_compile can resolve once instead of
paying the PATH scan and runnability probe three times per build.
functools.cache froze the ESPHOME_CCACHE_ENABLE/PATH decision for the
process lifetime, which a long-lived host like device-builder never
restarts, and forced a cache_clear fixture in the tests. The docstring
and test now pin the uncached delegation.
<= 2.6.2 instead of < 2.6.3: a 2.6.2 pre-release sorts above 2.6.2 and
belongs to the package-major-3 encoding, so the helper now describes
the same set as _format_framework_arduino_version and a 2.6.2-b1 pin
formats as it does on dev. The module never logged, so its _LOGGER and
logging import go.
cv.Invalid now carries path=[CONF_VERSION] so the rejection lands on
the framework version line the comment promised, matching the esp32
convention. framework_package_version raises for cores before 2.6.3
instead of encoding them wrongly for a caller that skipped the
PlatformIO path's era guard. get_build_env joins PATH from filtered
parts so an absent PATH cannot leave a trailing separator that the
shell reads as the current directory.
The installer's EsphomeError becomes cv.Invalid at the config
validator, and test_ccache_env clears the ambient environment so a
developer's exported CCACHE_DIR cannot fail it.
