Compact CLI list output by default

[andrei-hasna]

Summary

• Add shared compact CLI formatting helpers with a 20-row human default, truncation, readable tables, and concise hints.
• Add show/inspect, --verbose, --limit, and event --cursor discovery paths across the standalone CLI and embeddable commander adapter.
• Preserve full machine-readable JSON by default while documenting that explicit filters/limits/cursors select the requested page.
• Update README and tests for compact defaults, detail paths, cursor pagination, JSON stability, and commander parity.

Before / After

Worst noisy default in this package was an uncapped event history list.

Before, with 25 events:

$ events events list

2026-06-24T06:48:03.756Z\t...\taudit\tdemo.22\tinfo
2026-06-24T06:48:03.823Z\t...\taudit\tdemo.23\tinfo
2026-06-24T06:48:03.881Z\t...\taudit\tdemo.24\tinfo
2026-06-24T06:48:03.941Z\t...\taudit\tdemo.25\tinfo
# 25 rows printed, no cap or next-step hint

After:

$ events events list
TIME                      ID                                    SOURCE  TYPE     SEVERITY

2026-06-24T06:48:04.989Z  ...                                   audit   demo.25  info
Showing 20 of 25. 5 older omitted. Use --cursor <event-id> for older rows. Use --limit <n>, --verbose, events events show <id>, or events events list --json for more.

Validation

• bun test src/cli/cli.test.ts src/commander.test.ts
• bun run typecheck
• bun test
• bun run build
• Manual noisy-data probes for default event list, verbose event list, replay summary, and cursor pagination.

Adversarial Review

Ran a read-only adversarial reviewer focused on CLI compatibility, output ergonomics, and token bloat. Findings were reconciled before this PR:

• Event cursor pagination now fetches older omitted rows from the default newest page.
• README/help text now documents that JSON honors explicit filters, limits, and cursors.
