refactor(core): list which extension calls show under execute

[rekram1-node]

Extension calls only get a row under execute when they are listed. Today that list is fetch; the filesystem extension will add its entries here, and helpers like path.join will stay off the list.

 progressHooks  packages/core/src/codemode/tool.ts
-    "extension.before": (call) =>
-      start(call, { tool: call.name, status: "running", ...(call.name === "fetch" ? { input: display(call.args) } : {}) }),
+    "extension.before": (call) => {
+      switch (call.name) {
+        case "fetch":
+          return start(call, { tool: call.name, status: "running", input: CodeModeWeb.display(call.args) })
+        default:
+          return Effect.void
+      }
+    },

settle now returns Effect.void when a call has no row instead of re-recording the unchanged list, so unlisted calls emit no progress at all.

Verified against a local server: a fetch row still appears as running and settles to completed. bun run check 35/35; packages/core test/tool-execute.test.ts + test/codemode 27 pass.
