* feat(daemon): add disk-usage CLI to surface per-task / per-workspace footprint
Adds `multica daemon disk-usage [--by-workspace] [--by-task] [--top N]
[--output json]`, walking the workspaces root to report task and workspace
disk consumption without requiring a running daemon. Sizing reuses the GC
artifact patternSet (basename-only) so the reported "artifact" footprint
matches what `cleanTaskArtifacts` would actually reclaim, and the walk
honors the same safety contract: never enters .git, never follows symlinks,
counts only regular files.
Refactors WorkspacesRoot resolution into an exported `ResolveWorkspacesRoot`
so the read-only CLI picks the same root the running daemon would have.

* fix(daemon): distinguish displayed totals from scan totals; add workspace artifact ratio
- Track scan-wide TotalTaskCount / TotalWorkspaceCount on the report so
`--top N` no longer leaves the table footer claiming the truncated row
count is the full count. The CLI now prints a "Showing top N of M …
Displayed: X. Scan total: Y" line whenever truncation happens, and keeps
the bare "Total: …" footer for the un-truncated case.
- Add ArtifactRatio (0..1) on WorkspaceDiskUsage and TotalArtifactRatio on
the report. The workspace table renders an `ARTIFACT %` column. ratio()
guards size=0 so empty workspaces report 0% instead of NaN%.
