Fix SQLite recovery and preserve provider conversation context

Persist exact provider history and archived tool results independently of
terminal scrollback, and retain them when active run checkpoints are cleared.
Keep conversation and session saving independent of automatic reopening.

Deduplicate only committed session snapshots, retry transient SQLite write
contention, and enqueue conversation updates before writer shutdown. Recover
healthy startup data independently and protect unread records by disabling
writes with a persistent warning after an incomplete restore. Retain local
transcript pane conversation links across restarts.

Add regression coverage for SQLite failures, context round trips, legacy
fallbacks, and transcript snapshots.

+# Saving and restoring local data
+
+On macOS, Galaxy stores its local database at `~/.galaxy/galaxy.sqlite`.
+`general.restore_session` controls automatic reopening of the previous session;
+conversation history and session snapshots continue to be saved when it is off.
+Terminal scrollback retention does not limit persisted provider conversation context.
+
+New conversation records store the provider message history and tool-result archive
+alongside the progressive summary. Older records fall back to reconstructing the
+available task messages; provider details omitted by those older saves cannot be
+recovered exactly.
+
+Startup reads use a consistent SQLite snapshot and recover independent data domains.
+If a domain or saved tab/conversation cannot be read, Galaxy logs the failure, shows a persistent startup warning, and
+leaves database writing disabled for that launch so partial in-memory state cannot
+overwrite the original records. Repair the underlying problem and restart to resume
+saving. Snapshot deduplication happens only after a successful database commit;
+transactional snapshot and conversation saves retry transient database contention.

 # How to perform migrations
 
 ## How do migrations work?
@@ -27,20 +46,20 @@ This will create a new folder with an up.sql and down.sql.
 ## Step 3: Run the migration + generate the schema
 ```
 cd <repo root>
-diesel migration run --database-url="/Users/$USER/.galaxy-local/galaxy.sqlite"
+diesel migration run --database-url="/Users/$USER/.galaxy/galaxy.sqlite"
 ```
 This will run the migration on the same warp that runs when you run the app locally. This automatically generates or updates the `crates/persistence/src/schema.rs`. We do not make manual edits to `schema.rs`.
 
 You can also print the schema from a database that already has the migration with:
 ```
-diesel print-schema --database-url="/Users/$USER/.galaxy-local/galaxy.sqlite"
+diesel print-schema --database-url="/Users/$USER/.galaxy/galaxy.sqlite"
 ```
 
 ## Reverting/redo-ing migrations
 As you are writing features and changing branches, you'll want to undo migrations to fix your database and make it compatible with older code. Redo-ing can also be helpful as you are iterating on your schema.
 ```
-diesel migration revert --database-url="/Users/$USER/.galaxy-local/galaxy.sqlite"
-diesel migration redo --database-url="/Users/$USER/.galaxy-local/galaxy.sqlite"
+diesel migration revert --database-url="/Users/$USER/.galaxy/galaxy.sqlite"
