Stamp firmware with git hash: boot log, /debug page - #23

Conversation
No manual version number to forget to bump -- tools/version.py runs as a PlatformIO pre-build hook and embeds the short git commit hash (plus -dirty if the tree has uncommitted changes) as FW_GIT_HASH, shared by all board envs via xiao_base. Falls back to "unknown" outside a git checkout. Surfaced as the first line of the boot log (/log, /debug) and in a new header on the /debug page. Verified end-to-end on a flashed EE02 over Wi-Fi. See docs/versioning.md.
