feat(claude-code-settings): sync to Claude Code v2.1.143

[miteshashar]

Schema

• Add worktree.bgIsolation string enum ["worktree","none"], default "worktree" — "none" lets background sessions edit the working copy directly without EnterWorktree, for repos where worktrees are impractical. (v2.1.143, settings#worktree-settings)
• Add args: string[] to command hookCommand — exec form spawns command directly without shell interpretation so path placeholders never need quoting. (v2.1.139, hooks#command-hook-fields)
• Add continueOnBlock: boolean (default false) to prompt hookCommand — when prompt returns ok: false, feeds reason back to Claude and continues the turn instead of stopping. (v2.1.139, hooks#prompt-hook-configuration)
• Add subagentStatusLine top-level object {type: "command", command: string} for subagent status line configuration. (statusline#subagent-status-lines)
• Add statusLine.hideVimModeIndicator: boolean — suppress built-in vim mode display when the status line script renders it itself. (statusline#manually-configure-a-status-line)
• Add sandbox.failIfUnavailable: boolean — make sandbox startup a hard failure when required dependencies are missing. (sandboxing#enable-sandboxing)
• Add ANTHROPIC_WORKSPACE_ID env var — workspace ID for workload identity federation, scopes minted token to a specific workspace. (v2.1.141, env-vars)
• Add CLAUDE_CODE_OPUS_4_6_FAST_MODE_OVERRIDE env var — pin fast mode to Opus 4.6 instead of Opus 4.7 default. (v2.1.142, env-vars)
• Add CLAUDE_CODE_PLUGIN_PREFER_HTTPS env var — clone GitHub plugin sources over HTTPS instead of SSH. (v2.1.141, env-vars)
• Add CLAUDE_CODE_POWERSHELL_RESPECT_EXECUTION_POLICY env var — respect Windows PowerShell execution policy instead of bypassing it. (v2.1.143, env-vars)
• Add CLAUDE_CODE_STOP_HOOK_BLOCK_CAP env var — override default max consecutive Stop hook blocks (default: 8). (v2.1.143, hooks-guide)
• Update fastMode description: Opus 4.7 is now the default for fast mode since v2.1.142; add CLAUDE_CODE_OPUS_4_6_FAST_MODE_OVERRIDE=1 reference. (v2.1.142, fast-mode)
• Sort CLAUDE_CODE_DISABLE_ALTERNATE_SCREEN, CLAUDE_CODE_ENABLE_FEEDBACK_SURVEY_FOR_OTEL, CLAUDE_CODE_ENABLE_GATEWAY_MODEL_DISCOVERY, CLAUDE_CODE_FORCE_SYNC_OUTPUT, CLAUDE_CODE_PACKAGE_MANAGER_AUTO_UPDATE to correct alphabetical positions in $.env.properties (to pass coverage gate)

Tests

• Add worktree.bgIsolation: "none", subagentStatusLine, sandbox.failIfUnavailable: true, statusLine.hideVimModeIndicator: true, 5 new env vars (value "1"), prompt hook with continueOnBlock: true, and command hook with args (exec form) to modern-complete-config.json
• Add worktree.bgIsolation: "worktree" (default) and 3 new env vars (value "0") to edge-cases.json
• Add exec-form args to existing command hook and new prompt hook with continueOnBlock: true to hooks-complete.json

Negative tests

• Add worktree.bgIsolation: "isolated" (invalid enum) to invalid-enum-values.json
• Add invalid "yes" enum values for CLAUDE_CODE_OPUS_4_6_FAST_MODE_OVERRIDE, CLAUDE_CODE_PLUGIN_PREFER_HTTPS, CLAUDE_CODE_POWERSHELL_RESPECT_EXECUTION_POLICY

Skipped

• MultiEdit in permissionRule regex — already covered by open PR claude-code-settings: add MultiEdit to permission rule regex #5701
• $schema http:// → https:// redirect — cosmetic only

Supersedes #5665

Thanks for the PR!

This section of the codebase is owned by @domdomegg, @bogini, @sarahdeaton, and @ant-kurt - if they write a comment saying "LGTM" then it will be merged.

[domdomegg]

LGTM. Thorough sync — the new fields all line up with the v2.1.139–2.1.143 changes, descriptions cite the right docs/changelog anchors, and I like that you've covered each addition with positive tests plus negative tests for the new enums (bgIsolation, the 0/1 env vars). The alphabetical re-sort of the env properties to satisfy the coverage gate is correct too. Thanks for the detailed write-up.

@domdomegg Didn't end up merging. It seems like a flaky failure on CI.

Merging because @domdomegg is a code-owner of all the changes - thanks!
