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.
+Assign every input event exactly once: to an existing story ref, a new story key, or null when it is not part of any long-lived work (small talk, one-off questions).
+An event can join a story that had no events for a long time.
+Mark a story concluded only when an input event explicitly states it is finished, and cite that event; the cited event must be assigned to that same story or to one of its threads. Never conclude a story because it is quiet, and never conclude a long-lived feature because one task in it finished.

- FEATURE: a long-lived area of one project that keeps receiving work for weeks: a product module, subsystem, research topic or recurring activity. Name it after the area, never after one task.
- THREAD: a distinct sub-line inside a large feature: a sub-module, sub-topic, or one release line.
-Granularity:
- 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.
-Assign every input event exactly once: to an existing story ref, a new story key, or null when it is not part of any long-lived work (small talk, one-off questions).
-An event can join a story that had no events for a long time.
-Mark a story concluded only when an input event explicitly states it is finished, and cite that event; the cited event must be assigned to that same story or to one of its threads. Never conclude a story because it is quiet, and never conclude a long-lived feature because one task in it finished.
