fix: restore branding and version safeguards after upstream merge

Build regressions from upstream merge v1.2.26:
- Restore binary name to `altimate` (was `opencode`)
- Restore user-agent to `altimate/` (was `opencode/`)
- Restore `ALTIMATE_ENGINE_VERSION` build-time define
- Restore `OPENCODE_CHANGELOG` bundling
- Restore `sourcemap: "external"`
- Restore `--targets` flag support
- Restore backward-compatible `altimate-code` symlink
- Restore archive naming with `@altimateai/` prefix strip
- Remove `gh release upload` from build (handled by CI)
- Fix parser worker resolution via `import.meta.resolve`

Package.json cleanup:
- Remove junk fields (`randomField`) and echo-stub scripts
- Remove `opencode` bin entry
- Fix `altimate` bin path to `./bin/altimate`
- Delete `bin/opencode` file

Upstream merge safeguards:
- Add `build.ts`, `publish.ts`, `bump-version.ts`, `bin/**` to keepOurs
- Add `CHANGELOG.md` to keepOurs
- Extend version snapshot to include engine files (`pyproject.toml`, `__init__.py`)
- Add `sanitizePackageJson()` post-merge step
- Switch `fetchRemote()` to `--no-tags` to prevent upstream tag pollution

CHANGELOG fixes:
- Fix over-branding: upstream project references should say "OpenCode"

 #### 16. Anthropic OAuth Plugin
 - **Files**: `packages/opencode/src/altimate/plugin/anthropic.ts`
-- **Description**: Custom plugin implementing Anthropic OAuth 2.0 authentication via PKCE flow. Supports two login modes: Claude Pro/Max subscription (claude.ai) and API key creation via console (console.anthropic.com). Handles token refresh, injects required OAuth beta headers, prefixes all tool names with `mcp_` as required by Anthropic's OAuth endpoint, strips the prefix in streaming responses, and sanitizes system prompts (replaces "Altimate Code" with "Claude Code"). Also zeroes out model costs for Pro/Max subscribers.
