Fix agent list and detail rendering

[codeaholicguy]

Fixes #236

Summary:

• Replace compact emoji status cells with word labels and keyed colors in agent list rendering.
• Split interactive and durable list tables so mode-specific columns are clear.
• Add pluralized waiting summaries, future-aware relative time formatting, working-on recovery hints, and local-clock detail timestamps with width-derived separators.

Validation:

• npm ci
• cd packages/agent-manager && npm run build
• cd packages/channel-connector && npm run build
• cd packages/memory && npm run build
• cd packages/cli && npx vitest run src/tests/commands/agent.test.ts
• cd packages/cli && npx vitest run
• cd packages/cli && npx tsc --noEmit
• cd packages/cli && npx oxlint src
• npm run lint
