feat(gemini-local): export detectGeminiQuotaExhausted for plugin adapter reuse (#3416)

## Thinking Path

> - Paperclip orchestrates AI agents via pluggable server-side adapters,
one per provider / CLI backend
> - Each adapter package exposes a server entry point
(`@paperclipai/adapter-<name>/server`) that downstream consumers —
including plugin adapters that wrap or extend the stock behavior —
re-use for helper functions
> - `gemini-local`'s server entry re-exports a curated set of parse
helpers from `./parse.js` (`parseGeminiJsonl`,
`isGeminiUnknownSessionError`, `describeGeminiFailure`,
`detectGeminiAuthRequired`, `isGeminiTurnLimitResult`) so consumers can
classify provider output without reaching into the package's internals
> - `detectGeminiQuotaExhausted` lives in the same `parse.ts` file next
to `detectGeminiAuthRequired`, is defined with `export function`, and is
the package's single source of truth for "is this output a Gemini quota
hit?" — but it is missing from the entry-point re-export block
> - As a result, any consumer that wants to classify quota exhaustion
either has to deep-import from `./server/parse.js` (brittle against
future `exports`-field changes) or reimplement the regex locally (drift
risk against the authoritative heuristic)
> - This pull request adds `detectGeminiQuotaExhausted` to the existing
re-export block, placed next to its thematic sibling
`detectGeminiAuthRequired`, with no other changes
> - The benefit is one extra supported public symbol on
`@paperclipai/adapter-gemini-local/server` — a purely additive ergonomic
improvement with no behavior change and no existing consumer impact

## What Changed

- `packages/adapters/gemini-local/src/server/index.ts`: added
`detectGeminiQuotaExhausted` to the `export { ... } from "./parse.js"`
block, inserted between `detectGeminiAuthRequired` and
`isGeminiTurnLimitResult` (thematic grouping — both `detect*` helpers)

## Verification

Local verification against the branch commit (base: `upstream/master` at
`b649bd45`):

```
$ pnpm --filter @paperclipai/adapter-gemini-local typecheck
> @paperclipai/adapter-gemini-local@0.3.1 typecheck
> tsc --noEmit
(exit 0)

$ pnpm --filter @paperclipai/adapter-gemini-local build
> @paperclipai/adapter-gemini-local@0.3.1 build
> tsc
(exit 0)

$ cd server && pnpm exec vitest run src/__tests__/gemini-local-execute.test.ts
 RUN  v3.2.4

 ✓ src/__tests__/gemini-local-execute.test.ts (3 tests) 1487ms
   ✓ gemini execute > passes prompt via --prompt and injects paperclip env vars
   ✓ gemini execute > always passes --approval-mode yolo
   ✓ gemini execute > uses a compact wake delta instead of the full heartbeat prompt when resuming a session

Existing-consumer check — all references to `detectGeminiQuotaExhausted`
anywhere in the tree:

```
packages/adapters/gemini-local/src/server/index.ts:9    (this PR's new re-export)
packages/adapters/gemini-local/src/server/parse.ts:253  (the definition)
packages/adapters/gemini-local/src/server/test.ts:19    (intra-package import from "./parse.js")
packages/adapters/gemini-local/src/server/test.ts:174   (intra-package usage)
```

No cross-package consumer references the symbol today, so the new
re-export cannot break any existing import. It is strictly additive to
the public surface of `@paperclipai/adapter-gemini-local/server`.

## Risks

None. Purely additive re-export of a symbol that is already a named
export on `./parse.ts`. The clean-success path, failure paths, and all
other adapter behavior are untouched. No existing consumer is affected.

## Model Used

- **Provider**: Anthropic
- **Model**: Claude Opus 4.6 (1M context)
- **Interface**: Claude Code CLI
- **Role**: Upstream state verification (grep + diff against current
master), PR drafting against the `CONTRIBUTING.md` template, local
typecheck / build / test execution
- **Reasoning Mode**: Extended thinking enabled
- **Human oversight**: Noah Kellner reviewed the one-line re-export
addition and approved submission
