Description

Two independent fixes:

1. fix(chat) — tool execution progress never rendered in the web UI
(forge-ui/static/app.js)

The progress SSE handler looked for tool info in a data part of
status.message.parts, but the agent doesn't send it that way: the tool name
and phase arrive in task metadata (progress_tool / progress_phase) and
the human-readable line arrives as a text part. The part.kind === 'data'
branch therefore never matched and no tool card was ever appended.

The handler now:

• reads progress_tool / progress_phase from parsed.metadata
• maps the backend phases tool_start / tool_end onto the bare
  start / end values ToolCard expects
• takes the text part as the card's message
• keeps the existing replace-the-pending-start behaviour, now keyed off the
  metadata tool name (tools execute sequentially, so start/end never interleave)

2. fix(providers) — drop GPT 4.1 from the OpenAI model list
(forge-core/catalog/providers.go)

Comments out the GPT 4.1 / gpt-4.1 entry so it no longer appears in the
provider model picker. Left commented rather than deleted for easy restore.
