feat: OPE46-00044: QoL: Add compact summary view

[andrei-hasna]

Objective

OPE46-00044: QoL: Add compact summary view

Add monitor status --compact for single-line summary suitable for shell prompts or status bars.

MEASURED on origin/main: monitor status [machine] (src/cli/index.ts:350) only has -j/--json. Add --compact producing a single stable line (e.g. cpu 12% mem 43% disk 61%) suitable for a shell prompt or status bar, with no ANSI colour when stdout is not a TTY.

EXECUTION NOTES (added 2026-07-29 for autonomous execution)
Repo: github.com/hasna/monitor. CLI commands are registered in src/cli/index.ts (Commander). Verified against origin/main that this surface does NOT already exist.
Requirements: implement in src/ (not docs); keep existing output shapes and the -j/--json contract intact; reuse the existing helpers in that file (parseLimitOption, parseCursorOption, chalk formatting) rather than inventing new patterns.
Acceptance: bun run typecheck, bun run build and bun test are all green, and a new/extended test under src/ exercises the new behaviour (assert on the command's JSON output and/or exit code, not on colored text). No network, no live remote machines, no credentials — tests must run offline against local collectors/fixtures.

Verification

• policy source: base c4cbd1e (immutable commit — agent-proof)
• ⚠️ GATE-INTEGRITY: agent touched verify-bearing config — REVIEW (scripts.typecheck)
• containment: env — allowlist env, non-login shell, run-scoped HOME (registry auth seeded for install)
• install: pass
• typecheck: pass
• lint: pass
• build: pass
• test: pass
• doctor (ci): ok — 11 checks passed (1 advisory)
