Add claude-code-statusline to Usage & Observability

[ZWhiteTrace]

Resource

claude-code-statusline — Pure-bash Claude Code statusline with single-pass jq parsing.

Why it fits Usage & Observability

It's a statusline for Claude Code showing model, context window, rate limits, token usage, cache hit rate, API wait %, session cost, git state, and version — the same category as ccstatusline / ClaudeCodeStatusLine / pyccsl already listed.

Differentiation

• Performance: single-pass jq extraction via @sh + eval, ~20x faster (~25ms vs 400ms–1s) than the common pattern of spawning jq 20+ times
• Reliability: graceful fallback when jq fails, no broken UI
• Debuggability: STATUSLINE_DEBUG=1 mode dumps expanded variable assignments to stderr
• Zero runtime dependencies beyond jq, bc, git — single-file bash script, nothing to install
• Works with 10+ concurrent Claude Code sessions via lockfile-based git stats cache

Adapts automatically between cloud Claude (5h/7d rate limits) and local Ollama (tok/s inference speed).
