Bash tool: add run_in_background and description options

[evansenter]

[evansenter]

Companion Tools Needed

If run_in_background is implemented, clemini will also need:

KillShell

Kill a running background process by task ID.

{
  "task_id": "string (required)"
}

TaskOutput

Read output from a background task.

{
  "task_id": "string (required)",
  "block": "boolean (default: true) - wait for completion",
  "timeout": "number (default: 30000) - max wait time in ms"
}

These are required for full feature parity with Claude Code's background execution model.

[evansenter]

description parameter implemented in e0756e5.

The run_in_background feature is deferred - it requires task management infrastructure (spawning, tracking, output buffering, status checking) that's beyond the scope of a simple tool enhancement. Keeping this issue open to track that work, or can be split into a separate issue.

Closing as implemented. Both run_in_background and description parameters are now available in the bash tool (see src/tools/bash.rs). Related closed issues: #69 (run_in_background), #70 (KillShell for background task management).
