When running as a CC statusLine subprocess, stdout/stderr are piped and
COLUMNS may not be set. getTerminalWidth() falls back to
UNKNOWN_TERMINAL_WIDTH (40), which is not a real measurement.
Previously, this fallback value was treated as real terminal width in two
places:
- canCombine in renderExpanded(): context + usage lines were always split
because combined width exceeded 40 columns
- wrapLineToWidth in render(): all output lines were forcefully wrapped
at 40 characters, breaking the layout
Fix: introduce a widthIsReal guard that checks whether the resolved width
is the UNKNOWN_TERMINAL_WIDTH sentinel. When width is unknown:
- canCombine defaults to true (combine lines optimistically)
- wrapLineToWidth is skipped (wrapWidth=0 → no-op)
The host process (Claude Code) handles final display layout, so wrapping
at an arbitrary fallback value is harmful rather than helpful.

* fix: detect terminal width via stderr when stdout is piped
When Claude Code runs the statusLine as a subprocess, stdout is captured
(piped), so process.stdout.columns is undefined. With no terminal width,
long lines aren't wrapped by the HUD — the terminal wraps them silently
instead. Claude Code counts \n characters to determine how many lines to
erase on the next render, so the physical line count diverges from what
Claude Code expects. Over successive renders the cursor drifts upward into
the scrollback buffer, causing the terminal to jump to the top on every
tool execution (https://github.com/jarrodwatts/claude-hud/issues/209).
Fix: fall back to process.stderr.columns before the COLUMNS env var.
When the statusLine subprocess is spawned, only stdout is redirected;
stderr remains connected to the real TTY and returns the correct width.
With accurate width, lines are properly wrapped in the HUD output and
Claude Code's line count stays consistent.

* feat(config): add showSessionName toggle (default off)
Session name display from #155 is now opt-in via display.showSessionName
config. This addresses user feedback requesting the ability to hide the
session name. Added to setup onboarding and configure command flows.

* feat: show API billing indicator in model badge
When ANTHROPIC_API_KEY is present in the environment, display
[Opus | API] in red instead of [Opus | Max]. This helps users
who manage both Max plan and API key access (e.g., work vs personal)
immediately see when they're running on API billing.

New default: model+project on line 1, context+usage bars combined on line 2.
All optional features (tools, agents, todos) hidden by default with
setup onboarding step to enable them.
