Part IDs in chat.message hook missing required 'prt' prefix

[IvoryKir]

Bug

OpenCode now validates message part IDs with a Zod schema requiring them to start with "prt". The chat.message hook creates parts with IDs like supermemory-context-{timestamp} and supermemory-nudge-{timestamp}, which fail validation.

Error

ZodError: [
  {
    "origin": "string",
    "code": "invalid_format",
    "format": "starts_with",
    "prefix": "prt",
    "path": ["id"],
    "message": "Invalid string: must start with \"prt\""
  }
]

  at createUserMessage (/$bunfs/root/src/cli/cmd/tui/worker.js:108:35)

Reproduction

1. Install opencode-supermemory@2.0.4
2. Send the first message in a new session
3. Error fires on every first message (when context injection runs)

Root Cause

In dist/index.js, the chat.message hook creates parts with non-compliant IDs:

• Line ~14548: id: \supermemory-nudge-${Date.now()}``
• Line ~14582: id: \supermemory-context-${Date.now()}``

Meanwhile, generatePartId() (line ~14180) already generates correct prt_-prefixed IDs but is only used in injectHookMessage.

Fix

Use the prt_ prefix for all part IDs in the chat.message hook, e.g.:

id: `prt_supermemory-nudge-${Date.now()}`
id: `prt_supermemory-context-${Date.now()}`

Or reuse the existing generatePartId() function.

Environment

• opencode-supermemory: 2.0.4
• OpenCode: latest (bunfs-based CLI)
