fix(ns-api): write /tmp/TZ without a shell - #1865
Merged

Conversation
The timezone post-commit hook passed the UCI timezone value through "sh -c echo '<value>' > /tmp/TZ", so a value containing a single quote broke out of the quoting and the rest was executed as a command. Write the file directly with Python instead: no shell is involved, and the resulting content is unchanged. Assisted-by: Claude Code:claude-opus-5[1m]
