Updates the embedded Claude ACP adapter from 0.99.1 to 0.104.1, superseding the upstream release notices for 0.100.0, 0.101.0 and 0.101.1.

• Pin Claude Agent SDK and all eight native packages to 0.3.322 (Claude Code 2.1.322), and ACP SDK to 2.5.0.
• Regenerate the isolated lockfile and published baseline covering all 146 JavaScript modules and 114 production dependencies, retaining the body-parser and fast-uri security updates.
• Adapt runtime contracts to the upstream tool renderer and blockquoted transcript notices, and update the watcher expectations and compatibility documentation.

NeverWrite continues negotiating ACP v1. Upstream now defaults new sessions to Auto mode and supports idle compaction. The Goal integration tracked in #377 and #387 remains separate work.

Validation: 76 automated tests passed (6 runtime contracts, 9 preparation/watcher/smoke tests, 28 selection/terminal/session tests and 33 sidecar staging tests). Prepared the Linux x64 runtime and passed the real adapter/native CLI smoke against a local Anthropic mock: Sonnet 5.5 selection, concrete provider model ID, Read tool execution and cancellation. The upstream watcher confirms 0.104.1 matches the latest stable tag. Cross-platform and packaged application validation remain for CI.
