Adds JSON export actions to the Coder Agents Debug panel so users can download either the current chat's recent debug runs or one expanded run for support sharing.
The export reuses the existing chat debug endpoints and react-query cache, adds Storybook and unit coverage for the JSON envelope, and updates the chat debug logging docs with UI and cURL instructions.

<summary>Implementation notes</summary>
- Chat-level export fetches full detail for each listed debug run with `queryClient.fetchQuery(chatDebugRun(chatId, run.id))` and writes a single JSON file.
- Run-level export uses the already-loaded detail query data from an expanded run card.
- The JSON envelope includes `version`, `scope`, `exported_at`, `chat_id`, and either `runs` or `run`.
- The chat-level export reflects the current backend list endpoint behavior, up to the 100 newest debug runs.
- Agent-browser dogfooding verified files were downloaded and that `jq` validated the chat-level and run-level JSON contents.

Closes coverage gaps in `docs/ai-coder/agents/` and aligns nav
references with the current UI (post #24574 Behavior split, post #24644
Insights removal).
**Content fixes:**
- Replace site-wide `coder users edit-roles` flow with org-scoped
`agents-access` role (per migration `000475`). CLI examples now preserve
existing org roles since `edit-roles` overwrites the full set.
- Correct computer-use claim: supports Anthropic *and* OpenAI providers,
configured under the Virtual desktop experiment.
- New `platform-controls/experiments.md` covering Virtual desktop,
Advisor, and Chat debug logging (each as: what, how to enable, API).
Includes the Debug tab in the chat right panel.
- Trim `models.md` "Model overrides" to essentials: two layers (admin
subagent, user personal), contexts table, resolution order, API pointer.
- Remove retired `platform-controls/pr-insights.md` (page + manifest +
cross-links).
**Nav cleanup:**
- Admin-only tabs use the full `Agents > Settings > Manage Agents >
<Tab>` path; user-side tabs keep `Agents > Settings > <Tab>`.
- Replace stale "Behavior" references with Instructions / Lifecycle /
Experiments to match the current sidebar.
- Replace references to the removed top-bar Admin dialog with the
Settings sidebar.

<summary>Decision log</summary>
- Experimental features were originally drafted as a standalone Advisor
page plus inline sections in `platform-controls/index.md`. Consolidated
into one `experiments.md` since no individual feature warrants a full
page yet and parallel short sections are easier to scan.
- Reviewer feedback on early drafts: drop the inline experiments list
from `index.md` (avoid drift), drop the "users created before this role
was introduced" note (handled transparently by migration `000475`),
specify the full nav path for per-model pricing, link the
`type=computer_use` row in `architecture.md` to the Experiments page.
- CLI bulk-grant script previously called `edit-roles <user>
agents-access`. That replaces the user's full org role set, so the
script would silently strip `organization-admin`,
`organization-template-admin`, etc. Rewrote to read each user's current
roles, append `agents-access`, dedupe, and write the union back.
