feat(claude-code): sync settings and keybindings to Claude Code v2.1.200

[miteshashar]

Syncs claude-code-settings.json and claude-code-keybindings.json from the last synced v2.1.195 (#5867) up to v2.1.200.

Schema

Accuracy fixes

• Bug fix: maxSkillDescriptionChars renamed to skillListingMaxDescChars — the schema key didn't match the documented settings.json field name (settings.md), so users following the docs would fail validation.
• autoMemoryEnabled: corrected storage path to ~/.claude/projects/<project>/memory/ per memory#storage-location.
• CLAUDE_ENABLE_STREAM_WATCHDOG: default behavior updated — on by default for all providers since v2.1.196 (previously server-controlled on Anthropic API only).
• CLAUDE_CODE_DEBUG_LOGS_DIR, API_TIMEOUT_MS, outputStyle (missing "Proactive"), CLAUDE_CODE_DISABLE_MOUSE_CLICKS (incorrectly marked UNDOCUMENTED, now documented at fullscreen#keep-native-text-selection): description corrections per current docs.
• Doc-link upgrades: sandbox.enableWeakerNetworkIsolation → sandboxing, ANTHROPIC_BEDROCK_SERVICE_TIER → amazon-bedrock#service-tiers, several plugin/marketplace env vars, CLAUDE_CODE_SCROLL_SPEED/CLAUDE_CODE_DISABLE_MOUSE → fullscreen anchors.

New settings properties

• permissions.defaultMode/permissionMode: add "manual" as an accepted alias for "default" — changelog v2.1.200: the CLI/VS Code/JetBrains UI now labels this mode "Manual"; --permission-mode manual and "defaultMode": "manual" are accepted alongside default. permission-modes.md has not yet been updated to mention it — sourced from the changelog.
• attribution.sessionUrl (boolean, default true) per settings#attribution-settings.

Environment variables

Add 14 documented environment variables to $.env.properties:

• Per-signal OTLP mTLS overrides: OTEL_EXPORTER_OTLP_{LOGS,METRICS,TRACES}_CLIENT_{KEY,CERTIFICATE} (6 vars) per monitoring-usage#mtls-authentication.
• CLAUDE_CODE_DISABLE_BG_EXIT_HANDOFF (v2.1.196+), CLAUDE_DISABLE_ADOPT (v2.1.195+) — background session handoff controls.
• CLAUDE_AFK_COUNTDOWN_MS, CLAUDE_AFK_TIMEOUT_MS (v2.1.198+) — the settings-surface for the v2.1.200 changelog item "AskUserQuestion dialogs no longer auto-continue by default; opt into an idle timeout via /config".
• CLAUDE_CODE_BRIDGE_SESSION_ID (v2.1.199+), CLAUDE_CODE_DISABLE_EXPLORE_PLAN_AGENTS (v2.1.198+), CLAUDE_CODE_DISABLE_NOTIFICATION_PRESENCE_CHECK (v2.1.193+), VERTEX_REGION_CLAUDE_5_SONNET (v2.1.197+).

Keybindings

• builtinAction: add app:diffFileListUp, app:diffFileListDown (confirmed against generated v2.1.200 defaults; undocumented on keybindings.md, same treatment as existing app:toggleBrief/app:openArtifact).

Tests

• modern-complete-config.json, env-variables.json, edge-cases.json, basic-config.json, permissions-basic.json: coverage for every new/renamed property, enum value, and environment variable.
• invalid-enum-values.json: negative coverage for the new boolean-enum environment variables.
• claude-code-keybindings/all-contexts.json, current-actions.json: bind the two new actions.

Skipped

• Marketplace .git-suffix relaxation for git repository URLs — already covered by open PR feat(claude-code-settings): allow git marketplace URLs without .git suffix #5874 (independently verified correct against plugin-marketplaces#git-repositories).
• permissionRule tool-name pattern staleness (missing ~18 newer tool names, 3 stale ones) — large surface needing individual per-tool verification; deferred to a dedicated follow-up sync.

Superseded by #6131, which syncs all the way to v2.1.220 and includes every change from this PR plus the v2.1.200→v2.1.219 window. Closing in favour of that one to keep the review in a single place.
