Subject: [PATCH] fix(claude-local): use direct 4.5 model aliases (#3800)

## Thinking Path

> - Paperclip orchestrates AI agents for zero-human companies.
> - The `claude_local` adapter is the control-plane surface that turns
Paperclip agent settings into concrete Claude CLI invocations.
> - Issue #3777 reports that selecting Claude Haiku 4.5 from the
Paperclip UI causes Claude Code to request `claude-haiku-4-5-20251001`,
which some enterprise-scoped keys are not allowed to access.
> - In the current adapter model list, the direct Anthropic 4.5 entries
are version-pinned IDs, unlike the 4.6 entries which already use the
stable short aliases.
> - This pull request switches the direct 4.5 `claude_local` model
options to the short aliases Claude Code account access expects, while
leaving Bedrock-native IDs unchanged in the Bedrock-specific model list.
> - The benefit is that selecting Claude Sonnet 4.5 or Claude Haiku 4.5
from Paperclip no longer forces the CLI onto a more restrictive
versioned direct model name.

## What Changed

- Updated the direct `claude_local` adapter model list to use
`claude-sonnet-4-5` instead of `claude-sonnet-4-5-20250929`.
- Updated the direct `claude_local` adapter model list to use
`claude-haiku-4-5` instead of `claude-haiku-4-5-20251001`.
- Left the Bedrock-specific model IDs in `src/server/models.ts`
unchanged so AWS Bedrock routing still uses region-qualified native IDs.

## Verification

- `pnpm install --frozen-lockfile`
- `pnpm --filter @paperclipai/adapter-claude-local typecheck`
- Confirmed the only source change is
`packages/adapters/claude-local/src/index.ts`.

## Risks

- Low risk. This only changes the direct `claude_local` model IDs
advertised by Paperclip for the two 4.5 options.
- Bedrock behavior is unchanged because the Bedrock-native identifiers
are defined separately and were not modified in this PR.
- Existing 4.6 model options are untouched.

## Model Used

- OpenAI Codex on a GPT-5-class coding model with terminal tool use and
local code execution in this workspace.

## Checklist

details)
