v2.1.1

Fixed

• The token-savings benchmark (RoselineMCP.TokenBenchmark) now measures the model-visible MCP
  wire text: each tool payload is wrapped in the ToolResult<T> envelope and serialized with the
  MCP SDK's own serializer (McpJsonUtilities.DefaultOptions — minified camelCase, default JSON
  escaping), verified byte-identical to the text content block the real server emits over stdio.
  Previous figures measured each tool's bare, un-enveloped DTO with an indented serializer the SDK
  never uses. Re-measured headline: median 85% → 89%, pooled (size-weighted) 88% → 93%
  (568 tasks; on identical code the methodology correction alone moves the median 86% → 89% —
  minification outweighs the envelope + escaping overhead). All published numbers (README, site,
  OG card, manifest, docs) are synced. The benchmark also no longer depends on its working
  directory: tool-emitted relative paths resolve against the loaded solution's root, and a failed
  baseline file read now skips that task with a message instead of crashing the run.
• Solution/project auto-discovery is now nearest-level-first: the working directory wins when it has exactly one candidate, then each parent directory (up to 3) in order, then immediate subdirectories — so a solution in the cwd is no longer reported as "ambiguous" just because an ancestor directory (e.g. the main checkout above a git worktree) also has one; only a single level with multiple candidates of its own is an ambiguity.
• serverInfo.version in the MCP initialize handshake now reports the real package semver (the assembly's InformationalVersion minus any +buildmetadata suffix) instead of the MinVer-pinned {Major}.0.0.0 AssemblyVersion — a released 2.1.0 build introduced itself as 2.0.0.0.
• Social/Open Graph card (og.png) refreshed: the baked-in token-savings figure is now the
  median (85% at the time; since re-measured to 89%, see above — was the stale pooled 81%),
  and the card is regenerable from a checked-in template (website/og-card.html) instead of
  existing only as a rendered PNG; og:image:alt updated to match.
