* feat(coding-agent): add InlineExtension type for named inline extension factories
* test(coding-agent): update utilities and add regression test for InlineExtension
The Message types require content to always be present, but untyped JS
extension tools, hand-built histories, and old or hand-edited session
files can violate that contract, crashing rendering, compaction, and
provider request conversion with 'content is not iterable'.
Normalize null/missing content to an empty array at the ingestion
boundaries instead of guarding every consumer:
- transformMessages (choke point before every provider request)
- createToolResultMessage in the agent loop
- session entry loading (message and custom_message entries)
- extension custom messages (sendCustomMessage, before_agent_start)
- message_end extension replacements

The uuidv7 prefix is timestamp-derived and nearly constant between calls, so slicing the first 8 chars degenerated short ids to full-UUID fallbacks. Regression from 80c918c2 which replaced randomUUID with uuidv7.
Switch vitest packages (ai, agent, coding-agent) to the dot reporter
with silent: passed-only so passing tests stay quiet while failing
tests still print their console output and full diffs. Add the
github-actions reporter on CI for inline annotations. Switch the tui
node:test runner to the dot reporter as well.
GitHub's device flow documents slow_down as a rate limit: a poll that
arrives inside the throttle window is answered with slow_down instead of
the token, and the response's interval field reports the new required
minimum ("adds 5 seconds to the last interval"). A client that only
tracks its own +5s increment can stay behind the server's ratcheting
requirement when its timers fire early - common with WSL/VM clock drift
(microsoft/WSL#10006) - so every subsequent poll keeps hitting the rate
limit and login appears to hang forever even after the browser reports
the device as authorized.
Adopt the server-provided interval when a slow_down poll result carries
one, falling back to the RFC 8628 section 3.5 +5s increment otherwise.
GitHub Copilot passes the interval field through.
This restores part of the #1994 mitigations that were lost in the #4788
device-code refactor.

The question extension tool blocks on ctx.ui.custom() but omitted
executionMode, so multiple question calls in one assistant turn ran
under the default parallel mode and raced on the editor slot. Only the
last question rendered; earlier calls hung pending forever.
Set executionMode: "sequential" so the agent loop serializes the
batch. Wrappers already propagate the field to the core.

Picked up upstream models.dev/OpenCode catalog drift while
regenerating for the Fireworks GLM 5.2 Fast fix: Cloudflare AI Gateway
and OpenCode gain Claude Sonnet 5; OpenCode gains Kimi K2.7 Code and
MiniMax-M3; MiniMax model name formatting normalized to MiniMax-Mx.x.
Broaden the Fireworks GLM 5.2 special-case in generate-models.ts from
an exact id match to a glm-5p2 substring match, so the router variant
accounts/fireworks/routers/glm-5p2-fast also uses the OpenAI-compatible
endpoint and thinkingLevelMap instead of falling back to the default
Anthropic Messages config.

The Codex provider previously loaded node:os asynchronously during module evaluation. A fresh process that imports the provider and immediately starts an SSE request can build headers before that promise callback runs, so the first request reports User-Agent: pi (browser) in Node/Bun.
Reproduced against parent fd6659dd with a stubbed-fetch harness: 50/50 immediate first requests reported pi (browser) in both Node and Bun. The same harness on this fix reports the OS-specific user agent 50/50 in both runtimes.
Use process.getBuiltinModule("node:os") behind the existing Node/Bun runtime guard so OS metadata is available synchronously while still avoiding top-level runtime Node builtin imports that break browser/Vite builds.
