Spec §6.4: replace the scheme!=file / !isUnderRoot rejections with a single
!isAuthorable branch. isUnderRoot retained as a routing input. Per-condition
messaging (#24) kept for no-editor / empty-selection / non-{file,untitled}.

cowriting.editSelection collapsed four distinct failures (no editor / no
selection / unsaved / outside the workspace folder) into one misleading
"select some text in a workspace document first" warning — so editing a
selection in a file OUTSIDE the EDH workspace root (e.g. a content-repo file
while the EDH opens sandbox/) was rejected as if no text were selected.
- New pure, vscode-free src/workspacePath.ts: isUnderRoot() (separator-bounded
membership, fixing a latent startsWith() prefix collision where a sibling
whose name prefixes the root — e.g. vscode-cowriting-plugin-content vs
vscode-cowriting-plugin — falsely matched) + selectionRejection() (one
message per condition). Unit-tested (8 cases), incl. the reported bug.
- Wire isUnderRoot into all five membership checks: extension.ts (editSelection
guard + renderIfOpen) and the thread/attribution/proposal controllers.
