feat(capabilities): add isV013OrLater convenience predicate

Surfaces a v0.12 → v0.13 boundary check that doesn't proxy through any
specific feature flag. Used by WS-8 (redaction default-state hint copy,
"v0.13 features active" Settings badge in iOS WS-9) where the call site
isn't actually about a specific feature — it's about whether the host is
on the v0.13 line.

Equivalent to any individual v0.13 flag (e.g. `hasGoals`); both resolve
to the same `>= 0.13.0` threshold. Convenience exists to keep call sites
honest: `caps.isV013OrLater` reads better than `caps.hasGoals` when the
context isn't goal-related.

Tests: 4 new fixtures covering v0.13 host (true), v0.12 host (false),
empty/undetected (false), and v0.14 host (true). 19 total tests in the
suite, all passing.

 ## Hermes Version
 
-Targets Hermes v2026.4.30 (v0.12.0). Log lines may carry an optional `[session_id]` tag between the level and logger name — `HermesLogService.parseLine` treats the session tag as an optional capture group, so older untagged lines still parse.

-**Capability gating.** Scarf detects the target's Hermes version once per server connection via [HermesCapabilities](scarf/Packages/ScarfCore/Sources/ScarfCore/Services/HermesCapabilities.swift) (`hermes --version` → semver + `YYYY.M.D` parse). The resulting `HermesCapabilitiesStore` is injected on `ContextBoundRoot` (Mac) and `ScarfGoTabRoot` (iOS) via `.environment(_:)` and `.hermesCapabilities(_:)`; UI that depends on a v0.12+ surface (Curator, Kanban, ACP image input, `auxiliary.curator`, `prompt_caching.cache_ttl`, Piper TTS, Vercel terminal) reads it through the typed environment key. Pre-v0.12 hosts gracefully hide the new affordances rather than throwing on unknown CLI subcommands. Add a new flag at the top of `HermesCapabilities` whenever Scarf gains a release-gated UI surface.

Add a new flag at the top of `HermesCapabilities` whenever Scarf gains a release-gated UI surface — group flags by the Hermes release that introduced them (`MARK: v0.13 (v2026.5.7) flags`, etc.).
+
+**v2026.5.7 (v0.13.0)** added (Scarf-relevant subset; full v2.8.0 implementation lands across WS-2 through WS-9):
+
+- **Persistent Goals** — `/goal <text>` slash command locks the agent onto a target across turns. Checkpoints v2 single-store rewrite + auto-resume after gateway restart. Surfaced in Scarf chat as a non-interruptive command + a "🎯 Goal locked: <text>" pill in the chat header. Gated on `HermesCapabilities.hasGoals`.
+- **ACP `/queue` slash command** — queues a prompt to run after the current turn completes. Joins `/steer` in `RichChatViewModel.nonInterruptiveCommands` with a transient "Queued" toast. Gated on `hasACPQueue`. `/steer` now also runs as a regular prompt on idle sessions (`hasACPSteerOnIdle`).
+- **Kanban v0.13 reliability + recovery UX** — hallucination gate on worker-created cards, generic diagnostics engine (per-task distress signals), per-task `max_retries` override, multiline title/body create, `auto_blocked_reason` rendered in the inspector banner, darwin zombie detection, unify failure counter across spawn/timeout/crash. New fields decode through tolerant `HermesKanbanRun` / `HermesKanbanTaskDetail` extensions; pre-v0.13 hosts ignore unknown keys. Gated on `hasKanbanDiagnostics`.
+- **Curator archive + prune** — `hermes curator archive <skill>` + `prune` + `list-archived` subcommands. The synchronous manual `hermes curator run` blocks until done (pre-v0.13 returned immediately). Surfaced as an "Archived" tab in CuratorView with per-row Restore + Prune actions and a destructive prune-confirm sheet. Gated on `hasCuratorArchive`.
+- **Messaging Gateway expansion** — Google Chat (20th platform; `hasGoogleChatPlatform`), cross-platform allowlists (`allowed_channels` / `allowed_chats` / `allowed_rooms` per platform; `hasGatewayAllowlists`), per-platform `gateway_restart_notification` (`hasGatewayRestartNotification`), `busy_ack_enabled` toggle (`hasGatewayBusyAckToggle`), slash-command auto-delete TTL, `[[as_document]]` skill media routing directive, `hermes gateway list` cross-profile status verb (`hasGatewayList`).
+- **Provider catalog refresh** — new models on Nous Portal + OpenRouter: `deepseek/deepseek-v4-pro`, `x-ai/grok-4.3`, `openrouter/owl-alpha` (free), `tencent/hy3-preview`, `arcee/trinity-large-thinking` (with temperature + compression overrides). `x-ai/grok-4.20-beta` renamed to `x-ai/grok-4.20` — keep alias map. Vercel AI Gateway demoted to bottom of the picker. `image_gen.model` from `config.yaml` now honored by Hermes (was advertised but ignored pre-v0.13); surfaced in `Settings → Auxiliary` (`hasImageGenModel`). OpenRouter response caching toggle (`hasOpenRouterResponseCache`).
+- **MCP SSE transport** — MCP servers can be configured with SSE transport + `sse_read_timeout`. Surfaced in MCPServersView add-server flow alongside stdio/pipe. Gated on `hasMCPSSETransport`.
+- **Cron `--no-agent` mode** — script-only watchdog jobs that skip the AI call. Surfaced in CronView edit sheet. Gated on `hasCronNoAgent`.
+- **Web Tools per-capability backends** — `web_search` and `web_extract` can use distinct backends; SearXNG joined as a search-only backend. Surfaced in the Web Tools settings tab. Gated on `hasWebToolsBackendSplit`.
+- **Profiles `--no-skills`** — `hermes profile create --no-skills` for empty-profile creation. Surfaced as a toggle in the create-profile flow. Gated on `hasProfileNoSkills`.
+- **CLI / UX additions** — context compression count in the status feed (rendered next to the token count in chat status bar; `hasContextCompressionCount`), `/new <name>` slash-command argument (`hasNewWithSessionName`), `hermes update --yes` non-interactive (`hasUpdateNonInteractive`), `display.language` static-message translation (zh / ja / de / es / fr / uk / tr; `hasDisplayLanguage`), xAI Custom Voices (voice-cloning badge next to xAI TTS provider; `hasXAIVoiceCloning`).
+- **Server-side defaults flipped** — secret redaction defaults back to ON in v0.13 (was off by default in v0.12). The Settings redaction toggle remains for opt-out; the default-state hint reflects the v0.13 semantics when the host advertises v0.13+.
+- **`video_analyze` tool** — native video understanding on Gemini-class models. Hermes handles transparently inside the agent loop; Scarf has no UI surface yet but `hasVideoAnalyze` is reserved for future widget gating.
+- **`transform_llm_output` plugin hook** — plugin-author concern; surfaced indirectly through PluginsView when a plugin advertises the hook. `hasTransformLLMOutputHook` gates the metadata badge.
+- **Schema is unchanged from v0.11/v0.12** — same state.db columns. No migration needed.
