Bug Fixes

• OpenCode plugins were incompatible with OpenCode 1.2.x. Users saw OpenCode crash on startup with:
  TypeError: fn3 is not a function. (In 'fn3(input)', 'fn3' is an instance of Object)
      at <anonymous> (src/plugin/index.ts:90:28)
  
  Root cause: we shipped plugins as export default { id, server: async (...) => hooks } — an object. OpenCode 1.2.x’s plugin loader (packages/opencode/src/plugin/index.ts) does this:
  for (const [_name, fn] of Object.entries(mod)) {
    const init = await fn(input)  // ← line 90: expects fn to be a function
    hooks.push(init)
  }
  
  It iterates every module export (including default) and calls each one as a function. Our object export was never unwrapped — the runtime has no special case for a server: property, so { id, server }(input) threw fn is not a function. Fixed across all 3 plugins (inject-subagent-context.js, inject-workflow-state.js, session-start.js) by switching to the current factory-function shape:
  export default async ({ directory, client }) => {
    const ctx = new TrellisContext(directory)
    return {
      "tool.execute.before": async (input, output) => { /* ... */ },
      "chat.message": async (input, output) => { /* ... */ },
    }
  }
  
  This matches the documented Plugin type in @opencode-ai/plugin: (input: PluginInput) => Promise<Hooks>. Impact: any Trellis version (including 0.4.x stable) configured for OpenCode was affected as soon as OpenCode updated to 1.2.x. Upgrade to @mindfoldhq/trellis@beta to restore startup.
