Relates to CODAGT-713
Depends on #27284
This makes the per-template `agents_allowed` field authoritative in the API and chatd. It adds optional create and metadata update fields with the intended default and omission semantics, supports `agents-allowed:` template search, includes the value in telemetry, and makes `list_templates`, `read_template`, and `create_workspace` read the template row directly. Existing-workspace retries remain idempotent, and blocked same-organisation templates return an actionable message.
The experimental `/template-allowlist` routes remain temporarily because the shipped AI Settings page still calls them, but they no longer control chatd enforcement. #27514 moves that page to per-template metadata, #27515 removes the legacy storage, routes, SDK types, and utility, #27517 adds the CLI flags, and #27518 updates the platform controls documentation for the per-template model, directly addressing CRF-5 and CRF-6. The stack is intended to merge as a unit.
Fixes CODAGT-447.
Alternative implementation of https://github.com/coder/coder/pull/26212
and https://github.com/coder/coder/pull/25978
- Adds up to the first 1000 characters of `README.md` (with leading
frontmatter stripped) to `chattool.list_templates` output
- Adds up to 800 characters of `README.md` to `chattool.read_template`.
**Note:** skipping `toolsdk` versions to keep scope small.

Fixes CODAGT-175
Addresses a review finding in https://github.com/coder/coder/pull/23827
that the nil-guards for both `database.Store` and `chatID` are both dead
code in practice in the `chattool` package.
- Modifies the return signatures require passing both `database.Store`
and `chatID` explicitly as positional arguments instead of just
parameter struct keys.
- Drops the nil-guards for `database.Store` and `chatID`.
The chat tools (`read_template`, `create_workspace`) did not surface or
respect template version presets. Presets were invisible to the LLM and
preset parameter defaults were never applied at workspace creation. The
`toolsdk` MCP surface had the same gap (ref #24695, now subsumed here).
## What this changes
- **`read_template`** returns presets with `id`, `name`, `default`,
`description`, `icon`, `parameters`, and `desired_prebuild_instances`
(when set), so the LLM can pick the right preset and prefer
prebuilt-backed ones.
- **`create_workspace`** accepts a `preset_id`. The wsbuilder applies
preset parameter defaults and may claim a prebuilt workspace.
- **`start_workspace`** does *not* accept a preset. Presets are a
creation-time choice; subsequent starts use the workspace's existing
version and parameters. Users who need a specific preset or version on
an existing chat can create the workspace out-of-band (CLI / UI / API)
with the desired configuration and attach the chat to it.
- **`toolsdk`** gains `GetTemplate` (with presets including
`desired_prebuild_instances`), preset support on `CreateWorkspace`, and
preset + `rich_parameters` support on `CreateWorkspaceBuild`. The
`template_version_preset_id` description warns about preset/version
affinity.
