iOS port M0d: extract 6 portable ViewModels to ScarfCore

Fourth and final M0 sub-PR. Wraps up the ScarfCore extraction with the
ViewModels that have no dependency on Mac-target services or AppKit.
Views deliberately stay in the Mac target — see plan for rationale.

Moved (6 VMs):
  ActivityViewModel.swift      — HermesDataService consumer, SQLite3-gated
  ConnectionStatusViewModel.swift — @MainActor heartbeat for remote SSH
  InsightsViewModel.swift      — HermesDataService aggregator, SQLite3-gated
                                  (+ InsightsPeriod, ModelUsage, PlatformUsage,
                                   ToolUsage, NotableSession types; exports
                                   free functions formatDuration/formatTokens)
  LogsViewModel.swift          — HermesLogService consumer, fully portable
                                  (+ nested LogFile / LogComponent enums)
  ProjectsViewModel.swift      — ProjectDashboardService wrapper, portable
  RichChatViewModel.swift      — ~700 lines of ACP-event + message-group
                                  handling, SQLite3-gated
                                  (+ ChatDisplayMode, MessageGroup types)

Reverted in-flight:
  GatewayViewModel.swift — my audit missed that it calls
  `context.runHermes(...)`, a Mac-target-only extension. Not portable
  without moving HermesFileService too. Left in the Mac target.

Platform guards applied:
  - `#if canImport(SQLite3)` wraps entire files for ActivityVM, InsightsVM,
    and RichChatVM (they transitively depend on HermesDataService).
  - `#if canImport(Darwin)` around LocalizedStringResource displayName
    in LogsViewModel's nested LogFile and LogComponent enums.
  - `#if canImport(os)` around the unused Logger in
    ConnectionStatusViewModel (kept the field for future use).

Swift 6 / Observation notes:
  - `import Observation` explicitly added to each @Observable file.
    Mac target gets Observation via SwiftUI; ScarfCore doesn't import
    SwiftUI, so it needs the explicit module import. Observation ships
    in the Swift 5.9+ standard library on every platform.
  - Nested enums' `var id: String { rawValue }` had to be manually
    promoted to `public var id` since my sed only touches 4-space-indent
    declarations and the nested enum's members are at 8-space indent.
  - Two accidentally-publicized function-local `let` variables in
    InsightsViewModel reverted back to internal.
  - Sed adjustment: an earlier pattern was producing `@Observable public`
    which is a Swift syntax error. Fixed post-hoc by stripping the
    stray trailing `public` after the attribute; noted in the plan file
    as a checklist item for M1+ sed work.

Consumer import sweeps:
  4 Mac-target files gained `import ScarfCore` for the moved VM types:
  ContentView.swift, ChatView.swift, RichChatView.swift, and
  ConnectionStatusPill.swift.

Test coverage (M0dViewModelsTests): 14 new tests.
  - ConnectionStatusViewModel: local-always-connected, remote idle-start,
    Status Equatable pinning.
  - LogsViewModel: init defaults, filteredEntries across level / search /
    component filters, nested enum Identifiable ids and loggerPrefix.
  - ProjectsViewModel: .local context binding.
  - (SQLite3-gated, Apple-only):
    ActivityVM construction, InsightsVM period defaults and sinceDate
    ordering, ChatDisplayMode case coverage, RichChatVM empty-state
    invariants, MessageGroup derived properties.

Running `docker run --rm -v $PWD/scarf/Packages/ScarfCore:/work -w /work
swift:6.0 swift test` now reports 51 / 51 passing on Linux
(M0a 16 + M0b 18 + M0c 8 + M0d 9 + smoke 1 − 5 SQLite3-gated).
Apple-target CI should see 56 / 56 with the 5 gated tests added in.

Updated scarf/docs/IOS_PORT_PLAN.md with M0d's shipped state, the
Views-stay-Mac-only scope decision, and the sed-gotcha checklist
future phases should watch for.
