feat(agentapi,claude-code): add web_app variable to disable the web app

[blinkagent]

Adds a web_app variable (default: true) to both the claude-code and agentapi modules. When set to false, AgentAPI still runs but the web UI app icon is not shown in the Coder dashboard.

This mirrors the existing cli_app toggle pattern.

Changes

agentapi module

• New web_app variable (bool, default true)
• coder_app.agentapi_web now has count = local.web_app ? 1 : 0
• Task-safe: local.web_app is computed as var.web_app || local.is_task, where is_task = try(data.coder_task.me.enabled, false). This means the web app is always created when the workspace is a Task, regardless of the web_app variable.
• task_app_id output returns "" when local.web_app is false

claude-code module

• New web_app variable (bool, default true)
• TODO comment to wire web_app through to agentapi once published

Usage (once fully wired)

module "claude-code" {
  source  = "registry.coder.com/coder/claude-code/coder"
  ...
  web_app = false  # hides the Claude Code web UI from the dashboard
}

Setting web_app = false is safe even in templates that use coder_ai_task — the module detects Tasks via data.coder_task.me.enabled and automatically enables the web app.

Merge strategy

This needs to land in two steps:

1. Merge this PR — publishes the agentapi module with web_app support, and adds the web_app variable to claude-code (not yet wired through)
2. Follow-up PR — bump the agentapi version in claude-code and replace the TODO with web_app = var.web_app

While this is technically possible to add. I think we may need a better solution for this since the tasks ui will not work unless the claude-code coder app is available in the workspace.

For CI to pass we will need to defer these changes in a PR that we will make and merge after I test this logic, and then the CI will pass for both PR's it will just require a patch version bump for the claude-code module that can only be avoided if we split this PR into 2 for each module changed, and stagger their releases. @matifali

module "agentapi" {
  source  = "registry.coder.com/coder/agentapi/coder"
  version = "2.4.0"

  agent_id             = var.agent_id
  pass web_app    = var.web_app
  web_app_slug    = local.app_slug
  web_app_order  = var.order
  web_app_group = var.group

Pull request overview

Adds a web_app toggle (default true) intended to allow hiding the web UI app icon while keeping AgentAPI running, mirroring the existing cli_app pattern.

Changes:

• agentapi: introduce web_app variable and gate creation of coder_app.agentapi_web via count, with Task-safe override to always create the app in Tasks.
• agentapi: adjust task_app_id output to return an empty string when the web app is not created.
• claude-code: add a web_app variable and bump documented module versions (Claude Code to 4.9.0, AgentAPI dependency to 2.3.0), with a TODO to wire web_app through later.
