Minor Changes

• 91ae167: RPC surface expansion, branded identity types, and scope-bound liveness.

  Wired RPC methods go from 14 to 62 (of herdr's 89), the bulk of this
  release. New operations/ modules: workspace, tab, worktree,
  notification, integration, events, agent, agentReporting, plus
  claim and entity below. operations/pane.ts gains eight spatial
  combinators and sendKeys; operations/current.ts gains currentPaneById.
  Still unwrapped: plugin.*, client.window_title.*, server.*,
  popup.close, pane.graphics.*, and layout.apply/export/set_split_ratio
  — see TODO.md.

  Pane, Tab, and Workspace now carry a discriminating EntityTypeId tag
  plus Equal/Hash/Order traits, and are built with makePane/makeTab/
  makeWorkspace. This is a breaking change to construction: bare object
  literals ({ id, tabId, workspaceId }) are no longer assignable. The tag lives
  on the prototype, so spreading an entity drops it at runtime rather than
  producing a half-entity that compares by reference. Note the spread is still
  statically assignable to Pane — TypeScript tracks the symbol-keyed property
  through a spread even though JS does not copy it — so kind-dispatching
  combinators fail loudly on a detagged value rather than relying on
  exhaustiveness.

  The tag fixes a real soundness hole. Pane structurally contains every field
  of Tab, which contains every field of Workspace, so the previous
  field-presence guards (hasProperty(u, "id") for a workspace) returned true
  for all three kinds — a Pane passed where a Workspace was expected would
  typecheck and dispatch the wrong RPC. New sound refinements isPane/isTab/
  isWorkspace replace them everywhere.

  New claim/claimIn/withClaim tie a resource's liveness to a Scope:

  • claim(entity) forks a watcher on herdr's *.closed push stream and
    interrupts the claiming fiber if the resource is closed remotely, so
    multi-step work stops at the close instead of failing on a later RPC.
  • disconnectPolicy: "retain" (default) only watches; "destroy" also closes
    the resource when the scope ends.
  • claim takes its Scope from the requirements channel; claimIn takes one
    explicitly, for callers managing lifetimes by hand.

  New kind-polymorphic close/focus/rename dispatch on the tag, collapsing
  the three per-kind families into one surface each. move is deliberately not
  collapsed — movePane takes a destination union and returns the pane's fresh
  identity, while moveTab/moveWorkspace take an index and return void.

• d9b4bd3: Initial public release: typed Effect SDK for herdr.

  • Protocol layer (HerdrRpcs, identity/snapshot value objects, tagged error types)
  • Connection primitive (HerdrConnection) with per-call-dial wire adapter and scoped events.subscribe support
  • Service layer (HerdrSession) and domain combinators: splitPane, focusPane, closePane, runInPane (batch + streaming), waitForOutput, activePane/activeTab, focusedPane/focusedTab/focusedWorkspace, focusedPaneRef, currentPane/currentTab/currentWorkspace, listWorkspaces
