Subject: [PATCH] fix(installer): raise the shipped statusline refreshInterval
 from 1s to 30s

deployStatusline() wires every new install with refreshInterval: 1, so
Claude Code polls the statusline once per second.

Nothing on the bar changes that fast. A warm render of
LIFEOS_StatusLine.sh costs 0.28-0.29s. The usage figures it displays sit
behind a 900s cache TTL (USAGE_CACHE_TTL), and the script renders no wall
clock, so the fastest timer-driven value on the bar updates once every 15
minutes. A 1s poll re-renders it about 900 times per data change.

The waste is not the only cost. Public PR #1767 reports that Claude Code
terminates a statusline render which overruns its interval, and that the
killed renders leaked 244,760 scratch directories on a headless box until
the filesystem ran out of inodes.

30 is a conservative starting point, not a derived optimum. It is far
inside the 900s TTL of the slowest-moving source while cutting the duty
cycle from about 29 percent to about 1 percent. The principled value
tracks how often the underlying data actually shifts, so this number
should be revisited if the bar gains a faster-changing source. Everything
on the bar that moves on events rather than on a timer, such as the model
and the branch, still re-renders at turn boundaries regardless of this
interval.
