feat(claude-code): add managed_settings input for policy delivery via /etc/claude-code (#863)

## Problem

The module configures Claude Code's permission posture by reaching
around the permission system rather than through it:

- `scripts/install.sh` writes `bypassPermissionsModeAccepted`,
`autoModeAccepted`, and `primaryApiKey` directly into the user-writable
`~/.claude.json`. Any process in the workspace can read the API key or
flip the acceptance flags back.
- `scripts/start.sh` adds `--dangerously-skip-permissions` to every task
launch, even when the template author set an explicit `permission_mode`.
The README has to carry a security warning telling people the module
bypasses permission checks.
- `permission_mode`, `allowed_tools`, and `disallowed_tools` each plumb
through a different ad-hoc path (CLI flag, `coder` subcommand) instead
of a single policy surface.

## Change

Add a `managed_settings` input that renders to
`/etc/claude-code/managed-settings.d/10-coder.json`. Claude Code reads
that drop-in directory at startup with the highest configuration
precedence (above `~/.claude/settings.json` and project settings), so
template authors get an admin-controlled policy file that users inside
the workspace cannot override. The mechanism is a local file read with
no API call, so it works identically for the Anthropic API, AWS Bedrock,
Google Vertex AI, and AI Bridge / AI Gateway.

```hcl
managed_settings = {
  permissions = {
    defaultMode                  = "acceptEdits"
    disableBypassPermissionsMode = "disable"
    deny                         = ["Bash(curl:*)", "WebFetch"]
  }
}
```

Supporting changes:

- `install.sh` writes the policy file (root-owned, 0644) and stops
writing `bypassPermissionsModeAccepted`, `autoModeAccepted`, and
`primaryApiKey` into `~/.claude.json`. The API key is already exported
via `coder_env` as `CLAUDE_API_KEY`; duplicating it on disk is
unnecessary. `hasCompletedOnboarding` stays because there is no env-var
alternative for it.
- `start.sh` only adds `--dangerously-skip-permissions` for tasks when
no explicit `permission_mode` is set (same fix as #846; included here so
this PR is self-contained, happy to drop if #846 lands first).
- `permission_mode`, `allowed_tools`, and `disallowed_tools` are marked
deprecated and shimmed into `managed_settings.permissions` for one
release when `managed_settings` is not provided.
- README security warning rewritten to point at the policy mechanism
instead of telling people the module is unsafe by design.

## Relationship to #861

#861 strips this module to install-and-configure and removes
`permission_mode` / `allowed_tools` / `disallowed_tools` outright.
`managed_settings` is the natural replacement for those: it is
install-time (survives the `start.sh` removal), it covers everything the
dropped variables did plus `hooks`, `env`, `model`, `apiKeyHelper`, and
the rest of the settings schema, and it does not require the module to
know anything about how Claude is launched. If #861 lands first I will
rebase this on top and drop the deprecation shim and the `start.sh`
hunk.

## Validation

- `terraform fmt` / `terraform validate` clean
- New tests: `claude-managed-settings-written`,
`claude-managed-settings-legacy-shim`,
`claude-no-policy-keys-in-claudejson`, plus an assertion in
`claude-auto-permission-mode` that `--dangerously-skip-permissions` is
absent when a mode is set
- Manually verified `/etc/claude-code/managed-settings.d/*.json`
precedence in the Claude Code CLI source

Closes #818. Relates to #284, #846, #861.

Disclosure: I work at Anthropic on the Claude Code team. Happy to adjust
scope or split this further if that is easier to review.

+# Agent Firewall
+
+Installs [agent-firewall](https://coder.com/docs/ai-coder/agent-firewall) for network isolation in Coder workspaces.
+
+This module:
+
+- Installs agent-firewall (via coder subcommand, direct installation, or compilation from source)
+- Creates a wrapper script at `$HOME/.coder-modules/coder/agent-firewall/scripts/agent-firewall-wrapper.sh`
+- Writes a [default agent-firewall config](https://github.com/coder/registry/blob/main/registry/coder/modules/agent-firewall/config.yaml.tftpl) to `$HOME/.coder-modules/coder/agent-firewall/config/config.yaml` (customizable)
+- Provides the wrapper path, config path, and script names via outputs
+- Uses coder-utils and output `scripts` for synchronization. https://registry.coder.com/modules/coder/coder-utils?tab=outputs
+
+```tf
+module "agent-firewall" {
+  source   = "registry.coder.com/coder/agent-firewall/coder"
+  version  = "0.0.1"
+  agent_id = coder_agent.main.id
+}
+```
+
+## Examples
+
+Use the `agent_firewall_wrapper_path` output to access the wrapper path and `agent_firewall_config_path` to access config path in Terraform and pass it to scripts that should run commands in network isolation.
+
+### With Claude Code
+
+Use agent-firewall alongside the `claude-code` module to run Claude in a
+network-isolated environment.
+
+#### As an automated task
+
+```tf
+module "agent-firewall" {
+  source   = "registry.coder.com/coder/agent-firewall/coder"
+  version  = "0.0.1"
+  agent_id = coder_agent.main.id
+}
+
+resource "coder_script" "claude_with_agent_firewall" {
+  agent_id     = coder_agent.main.id
+  display_name = "Claude (Agent Firewall)"

+    coder exp sync start claude-agent-firewall
+  "${module.agent-firewall.agent_firewall_wrapper_path}" --config="${module.agent-firewall.agent_firewall_config_path}" -- claude -p "Fix issue #840 from coder/coder"
+  EOT
+}
+```
+
+#### As a Coder app
+
+```tf
+module "agent-firewall" {
+  source   = "registry.coder.com/coder/agent-firewall/coder"
+  version  = "0.0.1"
+  agent_id = coder_agent.main.id
+}
+
+resource "coder_app" "claude_with_agent_firewall" {
+  agent_id     = coder_agent.main.id
+  display_name = "Claude Code"
+  slug         = "claude-code"

+    #!/bin/bash
+    set -e
+    exec tmux new-session -A -s claude-code \
+      '"${module.agent-firewall.agent_firewall_wrapper_path}" --config="${module.agent-firewall.agent_firewall_config_path}" -- claude'
+  EOT
+}
+```
+
+## Configuration
+
+The module ships with a comprehensive default config based on the
+[Coder dogfood allowlist](https://github.com/coder/coder/blob/main/dogfood/coder/boundary-config.yaml). It covers Anthropic services,
+OpenAI services, version control, package managers, container registries,
+cloud platforms, and common development tools.
+
+The Coder deployment domain is automatically added to the allowlist using
+`data.coder_workspace.me.access_url`.
+
+By default the config is written to
+`$HOME/.coder-modules/coder/agent-firewall/config/config.yaml`. You can
+access the resolved path via the `agent_firewall_config_path` output. Override
+it in two ways:
+
+### Inline config
+
+Pass the full YAML content directly:
+
+```tf
+module "agent-firewall" {
+  source   = "registry.coder.com/coder/agent-firewall/coder"
+  version  = "0.0.1"
+  agent_id = coder_agent.main.id
+
+  agent_firewall_config = <<-YAML
+    allowlist:
+      - domain=your-deployment.coder.com
+      - domain=api.anthropic.com
+      - domain=api.openai.com
+    log_dir: /tmp/agent_firewall_logs
+    proxy_port: 8087
+    log_level: warn
+  YAML
+}
+```
+
+### External config file
+
+Point to an existing config file in the workspace. The module will not
+write any config and the `agent_firewall_config_path` output will point to
+your path. The file must exist on disk before agent-firewall starts.
+
+```tf
+module "agent-firewall" {
+  source   = "registry.coder.com/coder/agent-firewall/coder"
+  version  = "0.0.1"
+  agent_id = coder_agent.main.id
+
+  agent_firewall_config_path = "/workspace/my-agent-firewall-config.yaml"
+}
+```
+
+> **Note:** `agent_firewall_config` and `agent_firewall_config_path` are mutually
+> exclusive, setting both produces a validation error.
+
+See the [Agent Firewall docs](https://coder.com/docs/ai-coder/agent-firewall)
+for the full config reference.

+### Enterprise policy via managed settings
+
+The `managed_settings` input writes a policy file to `/etc/claude-code/managed-settings.d/10-coder.json` inside the workspace. Claude Code reads this directory at startup with the highest configuration precedence, so users cannot override these values in their own `~/.claude/settings.json`. This is a local file mechanism and works with any inference backend (Anthropic API, AWS Bedrock, Google Vertex AI, or AI Gateway).
