Trim fixed MCP context overhead#94

…e-line result banners ServerInstructions drops from 2,207 to 1,583 tokens with no rule removed: selection rules are tightened to terse form and moved ahead of the supported-types table so clients that truncate long instructions keep the behavior-critical part. Emitter banner notes collapse from 2-5 lines to one line per result, and the session header line shortens to "session: N calls - saved X - net Y after Z overhead". Header examples in mcp/README.md and copilot-instructions.md updated to match; test parsers for the session and repeat-view lines updated.

…own banner (#96) * Never downgrade a newer version pin in self-update; single-line Markdown banner SetPinnedVersion now refuses to lower an existing --version pin when the pinned version is newer than the target (core-version comparison via IsNewer, prerelease suffixes ignored). This stops the background self-update from stomping a deliberately pinned local dev build (e.g. 9.9.9-dev from a local feed) with the latest stable from nuget.org — which previously left the entry pointing at a version the configured --source doesn't have, so the server failed to launch. Stale-config re-pinning and the manual self-update path (#68) are unaffected: older pins still upgrade. MarkdownEmitter's banner note collapses from two lines to one, matching the other emitters after #94 (it was the only emitter missed in that pass). * Add PR number to CHANGELOG entries

The /usage breakdown attributes most session context to the tokensaver MCP server. Most of that share is tool results doing their job (they replace larger raw reads), but the fixed per-session overhead was genuinely trimmable. This PR cuts it without removing any behavior rule.
