Sync Claude Code upstream submodule da80366 → 2dc1e69 (v2.1.75)

[Copilot]

Advances the submodules/anthropic-claude-code pointer to 2dc1e69 (v2.1.75), covering CLI releases v2.1.72–2.1.74.

Upstream changes in range

• CHANGELOG.md — three release entries (v2.1.72, v2.1.73, v2.1.74): bug fixes for --effort, --continue, --agents, --plugin-dir; UX/perf improvements; no new CLI flags or breaking changes
• plugins/code-review/commands — adds confirmed: true to the MCP inline-comment tool call; internal plugin behavior only, not a CLI surface change

SDK impact

No C# SDK changes required:

• All mentioned flags (--effort, --continue, --agents, --plugin-dir) are already mapped in ClaudeExecArgs
• New settings (modelOverrides, autoMemoryDirectory) are JSON values passable via ClaudeExecArgs.Settings
• New env var (CLAUDE_CODE_DISABLE_CRON) is passable via ClaudeOptions.EnvironmentVariables
• "Opus 4.6" referenced in v2.1.73 CHANGELOG is a Bedrock/Vertex/Foundry provider default — no new model constant added (requires CLI verification per repo rules before any model ID is committed)
