v2.1.312

Claude Code v2.1.312 adds an oidc.user_id_claim option to the Claude apps gateway for identifying users by an id_token claim other than sub, and lets fullscreen users send a queued message by clicking the "to send now" hint. It fixes issues including managed settings not being fetched after VS Code extension sign-in, Claude overwriting large CLAUDE.md or rules files after reading only their start, per-directory and paths: skills not found after a Bash cd, and a Read tool PDF failure. Other changes include limiting prompt and agent hooks to 24 at a time per session, renaming the "session limit" to "5-hour limit" in usage messages, and various VS Code, cloud session, Remote Control, Claude Tag and Code Review fixes.
