[UX] Show initialization progress instead of static 'Setting up environment'

[randomm]

Problem

"Setting up environment" displays for 30+ seconds with no feedback. Users wonder if it's frozen.

Current State

oclite v0.1.0
⠋ Setting up environment

(sits here for 30+ seconds)

Desired State

Show what's actually happening:

oclite v0.1.0
⠋ Setting up environment
  ✓ Loading config
  ✓ Connecting to providers
  ⠋ Starting MCP servers...

Or simpler:

oclite v0.1.0
⠋ Loading config...
⠋ Starting MCP servers...
✓ Ready

Requirements

• Show progress during initialization
• Indicate which step is currently running
• Don't overwhelm with detail — keep it clean
• Gracefully handle slow operations (MCP, network)

Files

• packages/opencode/src/cli/lite/index.ts — main entry
• packages/opencode/src/cli/bootstrap.ts — initialization sequence

Acceptance Criteria

• User sees what's happening during init
• Slow steps are identifiable
• Clean, minimal output (not verbose logging)

Implemented in 450bee8: Init progress shows Loading plugins → Loading providers → etc.
