[Feature Request] CLI flag to load conversation from JSON file on startup

[nerdseverino]

Feature Request

Description

Add a CLI flag (e.g., --load <path>) to kiro-cli chat that loads a previously saved conversation JSON file directly on startup, similar to how --resume works for database sessions.

Current Behavior

To load a saved conversation from a JSON file, users must:

1. Start kiro-cli chat
2. Manually type /chat load <path>.json

This two-step process cannot be automated in headless mode (--no-interactive) since /chat load is an interactive command.

Proposed Behavior

# Load a saved conversation directly on startup
kiro-cli chat --load my-session.json

# Combine with other flags
kiro-cli chat --load my-session.json --trust-all-tools
kiro-cli chat --load my-session.json --agent my-agent

Use Cases

1. Workflow continuity: Quickly resume a specific exported session without interactive steps
2. Automation: Load a pre-built conversation context in headless/scripted pipelines
3. Team collaboration: Share conversation JSON files and load them directly
4. Session templates: Use saved conversations as starting points for recurring tasks

Consistency

The CLI already supports --resume (from DB) and --resume-picker (interactive). A --load <path> flag would complete the set by supporting file-based session restoration, consistent with the existing /chat load slash command.

Environment

• Kiro CLI (latest)
• Linux

Why is this marked as duplicate?
Both request CLI flags to enhance session resumption capabilities - the new issue wants --load for JSON files while #5477 wants --resume to accept session IDs. Both address limitations in current session loading options and propose similar CLI flag solutions for better workflow automation.
