feat(coder/modules/agentapi): add log snapshot capture on shutdown (#676 )

Captures the last 10 messages from AgentAPI when task workspaces stop,
allowing users to view conversation history while the task is paused.

The shutdown script fetches messages, builds a payload with last 10
messages, truncates to 64KB if needed (removes old messages first, then
truncates content of the last message), and posts to the log snapshot
endpoint.

Gracefully handles non-task workspaces (skips), older Coder versions
without the endpoint (logs and continues), and empty message sets.

Enabled by default via task_log_snapshot variable. Task ID is
automatically resolved from data.coder_task when available.

Updates coder/internal#1257

AgentAPI

Caution

We do not recommend using this module directly. Instead, please consider using one of our Tasks-compatible AI agent modules.

The AgentAPI module is a building block for modules that need to run an AgentAPI server. It is intended primarily for internal use by Coder to create modules compatible with Tasks.

module "agentapi" {
  source  = "registry.coder.com/coder/agentapi/coder"
  version = "2.1.0"

  agent_id             = var.agent_id
  web_app_slug         = local.app_slug
  web_app_order        = var.order
  web_app_group        = var.group
  web_app_icon         = var.icon
  web_app_display_name = "Goose"
  cli_app_slug         = "goose-cli"
  cli_app_display_name = "Goose CLI"
  module_dir_name      = local.module_dir_name
  install_agentapi     = var.install_agentapi
  pre_install_script   = var.pre_install_script
  post_install_script  = var.post_install_script
  start_script         = local.start_script
  install_script       = <<-EOT
    #!/bin/bash
    set -o errexit
    set -o pipefail

    echo -n '${base64encode(local.install_script)}' | base64 -d > /tmp/install.sh
    chmod +x /tmp/install.sh

    ARG_PROVIDER='${var.goose_provider}' \
    ARG_MODEL='${var.goose_model}' \
    ARG_GOOSE_CONFIG="$(echo -n '${base64encode(local.combined_extensions)}' | base64 -d)" \
    ARG_INSTALL='${var.install_goose}' \
    ARG_GOOSE_VERSION='${var.goose_version}' \
    /tmp/install.sh
  EOT
}

Task log snapshot

Captures the last 10 messages from AgentAPI when a task workspace stops. This allows viewing conversation history while the task is paused.

To enable for task workspaces:

module "agentapi" {
  # ... other config
  task_log_snapshot = true # default: true
}
