feat(storage): move desktop SQLite ownership into a storage utility process

Main no longer opens desktop business SQLite. A single utility-process
storage owner holds the Assistant, Knowledge, attachment, document-result,
remote-binding and native model-ledger databases and runs whole domain
transactions; Main and Runtime callers use explicit async domain operations.

- Remove the Main readWithFallback path and the supervision worker's
  separate business write connection; manifests are scanned read-only and
  committed by the sole writer.
- Remote events are ACKed only after commit; process loss reports
  unconfirmed writes instead of replaying them.
- Use native utilityProcess messaging with one in-flight bound (32) and
  ordered waiting instead of capacity rejection and retries.
- Start the storage process before the window so startup overlaps.
- Keep short tool output in memory and store full output once in owned
  storage; paging, branching, restart and deletion reuse that copy.
- Put required runtime launch files under goodbuddy-prefixed owned temp
  directories and reclaim confirmed stale ones; stop writing duplicate
  parsed.md.
- Add lint guards for SQLite ownership and architecture, concurrency
  acceptance fixtures, and maintenance/architecture documentation.

Validation: typecheck and lint pass. Alternating baseline (edf019aa) vs
candidate runs show no regression on single-session, C01, C02, C04 and a
5-minute C06; Main p99 drops from ~21 ms to ~16.7 ms under concurrency.
Fresh portable copy (1.75M events) upgrade content unchanged; real-model
output paging passes with 4 external requests. Full npm test runs had
1-9 different timing-sensitive failures per run that pass when rerun.
Not covered: C03 review publication, C07 source body, app-level C05.

+- A release, a version number, a single bug, a single day or a single task is never a feature. All release, packaging and version-sync work of a project belongs to one feature such as "发布与版本"; versions may be its threads.
+- Committing, pushing, testing or verifying the work of an area belongs to that area's feature, not to the release feature. The release feature holds only version bumps, release notes, tags, packaging and publishing.
+- Feature names never contain version numbers or dates.
+- Keep features few and broad; a project usually has 3 to 12. Before creating a feature, check EXISTING STORIES and the features already in your answer, and join the closest one when the topics overlap.
+- In a feature that has, or reaches with this input, at least ${threadEvents} events, place events in threads by sub-line (existing or new) and leave only general events on the feature itself. Threads of smaller features are folded into the feature.

+An event can join a story that had no events for a long time.
