adrianbonpin 88e7e45818 feat(mysql): native SQL execution — fix #41 type decoding, in-process restore, .sql open-with (#42 )

Fixes #41.

MySQL columns now decode by their declared type instead of a blind try_get chain,
so every non-string type (integers, DECIMAL, BIT, YEAR, DATE/TIME/DATETIME/TIMESTAMP)
renders its value instead of NULL. MySQL restore runs in-process over the sqlx driver
(no bundled MariaDB client, so MySQL 8 caching_sha2_password works) and the Clean toggle
is implemented. .sql files can be opened with Gridline from the OS file manager.

Verified: cargo test --lib 442 passed / 0 failed; bun run test 133 files / 1151 tests
exit 0; tsc clean; both live MySQL 8 integration tests pass with the bundled CLI hidden.

Smoke checklist — native MySQL execution (0.8.2)

These flows cannot be automated on this machine: RunEvent::Opened only fires for a bundled .app registered with LaunchServices, and a real MySQL 8 restore needs a live server. Run every box before publishing a draft release.

Build first (both scripts exist — build in desktop/package.json, the Tauri CLI via the tauri script in desktop/package.json):

bun run --filter gridline-desktop build
bun run --filter gridline-desktop tauri build

A. Association and OS open

The built .app appears under Finder → right-click a .sql file → Open With.
The previous default handler for .sql is unchanged (rank is Alternate). Refresh LaunchServices if it is stale: /System/Library/Frameworks/CoreServices.framework/Frameworks/LaunchServices.framework/Support/lsregister -f /Applications/Gridline.app
With Gridline closed, double-click a .sql file → the app launches with a query tab named after the file, containing the file's text.
With Gridline running, open another .sql file → a second tab appears (no second app instance, and no duplicate of the first tab).
Open the same file twice → the existing tab is focused; edits in it are NOT reset.
With no connection open, open a .sql file → Home is shown with a banner naming the file; after connecting, the tab opens automatically and the banner clears.
Open a file larger than 5 MB → nothing opens and no freeze occurs (a file over MAX_SQL_FILE_BYTES is rejected by the buffer and must be routed to Tools → Restore, whose own cap is 100 MB).
Open a .txt file via Open With → Gridline ignores it (no tab, no error dialog).
The notarized Gridline_0.8.2_*.dmg still carries the association and still launches.

B. Cell decoding (issue #41)

Connect to a MySQL database and open a table with INT/BIGINT columns: the primary key renders its values, not NULL.
Columns of type DECIMAL, DATE, DATETIME, TIMESTAMP, FLOAT, TINYINT, BIT and YEAR all render values.
Run the reporter's exact statement and confirm the ids are values: SELECT id, uuid, first_name FROM users ORDER BY id;
A BIGINT column renders as a string and a DECIMAL renders with its exact digits (no float rounding).
A VARCHAR column still renders as before (no regression on the types that worked).

C. Native restore

Tools → Restore against a MySQL 8 server whose user authenticates with caching_sha2_password (the case the bundled MariaDB client cannot reach): the restore completes.
The MySQL restore form is usable even when no mariadb/mysql client is installed.
clean ON into a non-empty target: objects the dump defines are replaced; an unrelated table created beforehand survives.
clean OFF into a non-empty target: fails with table already exists, and the error names the statement position.
A dump containing a trigger or stored routine (with DELIMITER) restores without a syntax error.
Cancel a long restore → it stops and reports cancellation rather than running to completion.
The form states that a failed MySQL restore cannot be rolled back.

D. Suite

cd desktop/src-tauri && cargo test --lib → 0 failures.
cd desktop && bun run test → 0 failures.
cd desktop && bunx tsc --noEmit → clean.
