Спампаваць Claude Code 2.1.86

- Added X-Claude-Code-Session-Id header to API requests so proxies can aggregate requests by session without parsing the body
- Added .jj and .sl to VCS directory exclusion lists so Grep and file autocomplete don't descend into Jujutsu or Sapling metadata
- Fixed --resume failing with "tool_use ids were found without tool_result blocks" on sessions created before v2.1.85
- Fixed Write/Edit/Read failing on files outside the project root (e.g., ~/.claude/CLAUDE.md) when conditional skills or rules are configured
- Fixed unnecessary config disk writes on every skill invocation that could cause performance issues and config corruption on Windows
- Fixed potential out-of-memory crash when using /feedback on very long sessions with large transcript files
- Fixed --bare mode dropping MCP tools in interactive sessions and silently discarding messages enqueued mid-turn
- Fixed the c shortcut copying only ~20 characters of the OAuth login URL instead of the full URL
- Fixed masked input (e.g., OAuth code paste) leaking the start of the token when wrapping across multiple lines on narrow terminals
- Fixed official marketplace plugin scripts failing with "Permission denied" on macOS/Linux since v2.1.83
- Fixed statusline showing another session's model when running multiple Claude Code instances and using /model in one of them
- Fixed scroll not following new messages after wheel scroll or click-to-select at the bottom of a long conversation
- Fixed /plugin uninstall dialog: pressing n now correctly uninstalls the plugin while preserving its data directory
- Fixed a regression where pressing Enter after clicking could leave the transcript blank until the response arrived
- Fixed ultrathink hint lingering after deleting the keyword
- Fixed memory growth in long sessions from markdown/highlight render caches retaining full content strings
- Reduced startup event-loop stalls when many claude.ai MCP connectors are configured (macOS keychain cache extended from 5s to 30s)
- Reduced token overhead when mentioning files with @ — raw string content no longer JSON-escaped
- Improved prompt cache hit rate for Bedrock, Vertex, and Foundry users by removing dynamic content from tool descriptions
- Memory filenames in the "Saved N memories" notice now highlight on hover and open on click
- Skill descriptions in the /skills listing are now capped at 250 characters to reduce context usage
- Changed /skills menu to sort alphabetically for easier scanning
- Auto mode now shows "unavailable for your plan" when disabled by plan restrictions (was "temporarily unavailable")
- [VSCode] Fixed extension incorrectly showing "Not responding" during long-running operations
- [VSCode] Fixed extension defaulting Max plan users to Sonnet after the OAuth token refreshes (8 hours after login)
- Read tool now uses compact line-number format and deduplicates unchanged re-reads, reducing token usage
