acec4b29ba Add elicitation confirmations and udev rule tool 
Write tools now prompt the user via MCP elicitation before
modifying OTP EPROM. Falls back to no confirmation if the
client doesn't support elicitation.

lock_device always requires confirmation — refuses without it.

New tool: setup_udev_rule
- Auto-generates symlink name from product string
- Installs rule to /usr/lib/udev/rules.d/
- Elicits user permission before sudo operations

ff12b9450f Fix MCP server startup: remove pre-run library init 
Native library calls during startup interfered with FastMCP's
stdio transport initialization. Library is now loaded lazily on
first tool call instead.
