Status line: custom segments tuned for fleet bars; slim frank-archon label

Named presets silently ignore leftSegments/rightSegments - the nerd
preset's baked arrays were what we saw, and the configured arrays were
dead. preset: custom with explicit arrays: chip (right) = token_in,
token_out, cost, context_pct, time_spent; strip (left) = session_name,
vim, mode, hostname, model, path, git (branch text off - worktree
branches are autogenerated; dirty badges kept), pr. Cut tok/s duplicate,
clock, cache trio, context_total, subagents, session hash. Composer
shape stays claude after live box/band/rule trials. models.yml display
name frank-archon drops the (dankserver) suffix; id untouched.
Docs: pi/statusline.md records the preset-vs-custom trap, shape->segment
routing, and the context-meter truth.
