fix(memhub): restore and freeze the home when an upgrade migration fails

A failed SDK migration left a half-migrated home (schema migrations,
moved legacy work, renamed Chroma collections) that the next run
resumed on top of, the maintenance fence re-enabled the LaunchAgent so
launchd retried at once, a deferred service idled forever, and capture
hooks kept writing into the legacy database.

Restore: before the first mutation the run records a restore point
(the pre-cutover bundle, or a fresh bundle when resuming an old ledger
row). Any failure before SDK authority is committed restores the
management database (with WAL), config.json and hy-memory/governed-v2
through a verified staging copy and a journaled rename swap; the failed
state is kept aside in backups/sdk-migration-failed/. A failure after
the commit, or an unreadable authority, never restores. An interrupted
swap is finished on the next start; meanwhile status reports required
and Core refuses to serve. The migration's own code stays the result;
the restore outcome is logged and reported separately.

Freeze: a deferred migration turns the service enable marker off, makes
the runtime service exit instead of idling, and leaves a frozen capture
fence that hooks honour. Desktop launch, memhub install/upgrade and now
start/restart re-run the migration and unfreeze on success, restoring
the previous auto-start.

The failure dialog says when data was restored, and its GitHub issue now
prefills the body: from/to version, code, failing step, whether data was
restored, macOS version and the log path shown with ~. migrate.invoked
records the pre-upgrade version. sdk_data_plane_* codes now reach the
dialog too.

+## Hy Memory 2.0.6 — 2026-10-27
+
+- Published
+  [`hy-memory==2.0.6`](https://pypi.org/project/hy-memory/2.0.6/).
+- `search(..., rerank=False)` skips every reranking stage for that one
+  call (the local cross-encoder, the memory-graph rerank, and the BM25 rerank of
+  working/coding facts), so results come back in retrieval-score order. The
+  flag travels on the read request, so concurrent searches do not affect each
+  other. The default (`True`) keeps current behavior; `/api/v1/search` accepts
+  it too.
+- MMR diversity selection now runs only when the requested `limit` is
+  below 20 (`MMR_MAX_TOP_K`) and is skipped for larger limits, where its
+  quadratic token-overlap pass is slow and gains little. Previously it ran for
+  every limit. `MEMORY_HYBRID_V2_MMR_LAMBDA` still sets the weight.
+  Near-duplicate demotion follows the same gate: it compares each candidate
+  with every earlier non-duplicate, which is quadratic in a pool that grows
+  with `limit`, and large result pages should show similar items anyway.
+- `search(scene="all")` searches chat, working and coding at the same time
+  and merges them with Reciprocal Rank Fusion (k=60) over each scene's own
+  ranking, so no scene is crowded out by the other scenes' score scales. Each
+  result says which scene and kind it came from. A scene that fails or is turned
+  off is reported in `errors` and does not fail the search. Source filters apply
+  to all three.
+- `list_memories(scene="all")` lists chat, working and coding memories
+  together, newest update first, with `limit`/`offset` paging over the merged
+  order and `total` summing all three. `scene="coding"` and `"working"` now
+  honor `include_sources` / `exclude_sources`, and `total` counts only the
+  filtered memories.
+- `update()` and `delete()` now work on working/coding experiences and
+  facts, not just chat memories. They take the same optional `kind` / `variant`
+  as `get()`, and an ID found in more than one place raises
+  `AmbiguousMemoryIdError` instead of guessing. Updating an experience replaces
+  its solution and keeps its task, unless a new `task=` is also passed; updating
+  a fact replaces its statement. Deleting removes the stored row and its vectors.
+- `list_memories(scene="chat" | "coding" | "working")` lists one kind of
+  memory. `coding` and `working` list that scene's whole store, newest update
+  first (`workspace_id` still narrows it), and `total` is now the real count
+  rather than the page size. The new `memory_stats()` returns the count and the
+  latest created/updated time for each scene and their total, without reading
+  any memory text. Previously coding and working memories could not be listed
+  or counted without a workspace, so a library of 45 memories listed 22.
+- Reconcile keeps time order. Both reconcile prompts now state that only
+  `memory_at` decides which memory is newer, that an older memory must never
+  supersede or overwrite a newer one, and that an unknown time is not newer;
+  the Chinese prompt now lists `memory_at` among the new-memory fields. The
+  reconciler also enforces this in code: a SUPERSEDE or UPDATE aimed at a memory
+  with a later `memory_at` becomes an ADD, so the newer memory stays current.
+- The HTTP server returns 409 `ambiguous_memory_id` and 400 for a bad
+  `kind`/`variant` instead of 500, passes `kind`/`variant` (and `task` on PUT)
+  to get/update/delete, and no longer reads a PUT/DELETE query string as part
+  of the memory id.
+- `memory_stats()` reads working/coding times, which are stored as naive UTC,
+  as UTC rather than local time.

+A migration that fails before SDK authority is committed has already changed

+2. its database, config and SDK root are copied next to their live places and

+   `backups/sdk-migration-failed/` and the staged copies are renamed in.
+
+A rename either happened or did not, and each step is idempotent, so a process
