Devin Foley ea7f53fd7d Handle Gemini CLI v0.38 stream-json wire format across parser, UI, and CLI formatter (#5273)
## Thinking Path

> - Paperclip orchestrates AI agents for zero-human companies
> - Each agent uses an adapter that drives a CLI (Claude, Gemini, Codex,
etc.)
> - The Gemini adapter parses a JSONL transcript stream the CLI emits to
learn what the model said
> - Gemini CLI v0.38 changed the transcript shape: assistant text now
comes through `type=message` with `role`/`content` and terminal status
comes through `type=status` / `type=stats`
> - The existing parser was written against the older `type=assistant` /
`type=result` shape, so post-v0.38 outputs left the parsed summary empty
and downgraded the SSH hello probe to "unexpected output"
> - This pull request updates every Gemini consumer (server parser, UI
parser, CLI formatter) to accept the v0.38 shape while keeping the
legacy shape working
> - The benefit is the Gemini adapter handles current upstream output
without losing backward compatibility, with explicit test coverage for
both shapes

## What Changed

- `packages/adapters/gemini-local/src/server/parse.ts` recognizes
`type=message` events with role/content and stops downgrading them
- `packages/adapters/gemini-local/src/ui/parse-stdout.ts` mirrors the
parser changes for the live UI transcript
- `packages/adapters/gemini-local/src/cli/format-event.ts` formats the
new event shape correctly for CLI output
- `parse.test.ts` and `parse-stdout.test.ts` add v0.38 coverage;
`gemini-local-adapter.test.ts` and `execute.remote.test.ts` switch
happy-path fixtures to the current real wire format and keep dedicated
tests for the older schema

## Verification

- `pnpm vitest run --no-coverage --project
@paperclipai/adapter-gemini-local` — full suite passes including new
v0.38 cases and preserved legacy cases
- `pnpm typecheck` clean

## Risks

Low risk — additive event handling. Legacy event shape path is preserved
with its own tests, so existing fixtures continue to parse identically.

## Model Used

Claude Opus 4.7 (1M context)
