feat(kanban): v0.13 diagnostics + recovery UX (WS-3)

Layers Hermes v0.13's reliability + recovery affordances on top of the
v2.7.5 Kanban v3 board. New surface — gated end-to-end on
`HermesCapabilities.hasKanbanDiagnostics` (>= v0.13.0):

- **Hallucination gate.** Worker-created cards land in `pending` until
  the user verifies the underlying work exists. Inspector renders a
  yellow Verify / Reject banner above the body; cards dim to 0.6 with
  a question-mark glyph. Verify is optimistic — banner clears
  immediately, polling confirms. Reject routes through
  `comment` + `archive` so there's an audit trail.
- **Generic diagnostics engine.** `HermesKanbanDiagnostic` (new model +
  typed-mirror enum `KanbanDiagnosticKind`) renders cross-run signals
  on the inspector header and per-run signals under each Runs row.
  Card footer gains a stethoscope dot when any signal is attached.
- **`max_retries` create-time field + inspector chip.** Toggle-gated
  Stepper in the create sheet sends `--max-retries N`; chip on the
  inspector header reads it back read-only with a tooltip explaining
  there's no update verb.
- **Multi-line title input.** Create sheet's title becomes a
  `TextField(axis: .vertical, lineLimit: 1...4)`. Newlines are stripped
  client-side on pre-v0.13 hosts (which truncate at the first `\n`).
- **Auto-blocked reason banner.** When `task.auto_blocked_reason` is
  set, replaces the generic "Last run: blocked" with a red banner
  rendering the server reason verbatim. Card footer shows a 1-line
  truncated copy in red.
- **Tolerant decode contract.** Every new field is `Optional` with
  `decodeIfPresent`; diagnostics arrays use `try?` so a single
  malformed entry doesn't poison the row. v0.12 hosts decode unchanged.

Implements WS-3 of Scarf v2.8.0 (Hermes v0.13.0 catch-up).
Plan: scarf/docs/v2.8/WS-3-kanban-v0.13-plan.md (on
coordination/v2.8.0-plans).

TODOs marked inline pending integration against a live v0.13 binary:
WS-3-Q1 (verify verb name), WS-3-Q2 (diagnostics envelope vs task),
WS-3-Q4 (failure_count placement), WS-3-Q5 (darwin-zombie kind
string), WS-3-Q6 (max_retries default).
