<issue_title>[enhancement] Bundle GitHub Copilot CLI for Zero-Config Installation Experience</issue_title>
<issue_description>## Background

Recent work in the Copilot SDK has focused on bundling the GitHub Copilot CLI binary to simplify distribution and eliminate manual installation steps:

Go SDK bundling support: PR colindembovsky/planeteer#414 by Quim Muntal (merged Feb 12, 2026) introduces embedding the CLI binary directly in Go applications. The PR describes a mechanism for embedding, unpacking, versioning, file locking, and hash validation.

Python wheel fix: PR colindembovsky/planeteer#419 by Steve Sanderson (Feb 10, 2026) ensures the bundled CLI binary has executable permissions.

Cross-platform bundling: The v0.1.23 release notes highlight "Bundling" (PR colindembovsky/planeteer#382) as a key feature across SDKs.

Commit references:

f1d8cc1 - Go bundling implementation

4dc5629 - Python executable permissions

Proposal

Adopt the CLI bundling approach for Planeteer's Node.js/TypeScript distribution. This would eliminate the current requirement for users to separately install @github/copilot CLI and authenticate before using Planeteer.

Implementation approach:

Investigate if the TypeScript/JavaScript SDK supports bundling (or if it requires custom packaging)

If supported: Add bundling configuration to package.json build scripts

If not yet supported: Create a postinstall script that downloads the correct CLI binary for the user's platform (similar to Electron's approach)

Update src/services/copilot.ts to check for bundled CLI first, falling back to system-installed CLI

Handle auto-updates: Check CLI version on startup and download newer versions if available

Update README prerequisites to remove the manual CLI installation step

Benefit

Zero-config experience: Users can run npm install -g planeteer && planeteer without manual CLI setup

Version consistency: Bundling ensures Planeteer uses a CLI version that's been tested with the SDK version

Distribution simplicity: Single npm package contains everything needed

Reduced support burden: Eliminates "CLI not found" errors and authentication confusion

Onboarding speed: New users can start using Planeteer in seconds, not minutes

Acceptance Criteria

Bundled CLI binary included in npm package for Linux, macOS, and Windows

src/services/copilot.ts detects bundled CLI location and uses it by default

Fallback logic: if bundled CLI missing/corrupt, attempt to use system-installed CLI

Version check on startup compares bundled CLI version with latest available

Auto-update mechanism downloads newer CLI versions to user's home directory cache

File locking prevents concurrent update attempts (if multiple Planeteer instances run)

Hash validation ensures downloaded binaries aren't corrupted

README prerequisites section updated to reflect zero-config installation

Build script generates platform-specific packages or uses universal bundling approach

Integration test verifies bundled CLI works on fresh system without pre-installed CLI

Pull request overview

This PR aims to enable a zero-config Planeteer install by locating and using the GitHub Copilot CLI binary that is bundled via @github/copilot-sdk optional dependencies, while retaining a system-CLI fallback and surfacing CLI version/source in the UI.

Changes:

Added a CLI locator utility that searches for bundled Copilot CLI binaries and falls back to PATH lookup.
Updated Copilot SDK client initialization to pass an explicit cliPath (with improved troubleshooting errors).
Displayed CLI version/source on the home screen and updated README prerequisites/troubleshooting.

Reviewed changes

+        `Failed to start GitHub Copilot CLI.\n\n` +
+        `Error: ${message}\n\n` +

+        `  3. Proper permissions to execute the CLI binary`
+      );


The rethrown error from c.start() drops the original error object/stack, which makes diagnosing CLI startup failures harder. Consider preserving the original error as cause (or otherwise propagating the original stack) while still adding the extra troubleshooting context.

Fixed in eaa681b - now using { cause: err } to preserve the original error object and stack trace while adding troubleshooting context.

+    });
+    const path = result.trim().split('\n')[0];
+
+    if (path && existsSync(path)) {
+      return path;
+    }
+  } catch {
+    // Ignore errors - CLI not in PATH


findSystemCli() runs execFileSync(which/where, ...) without a timeout. If PATH lookup hangs (network-mounted PATH entries, misconfigured shell hooks, etc.), Planeteer can block indefinitely during startup. Consider adding a short timeout and handling timeout errors explicitly.

Suggested change

});

const path = result.trim().split('\n')[0];

if (path && existsSync(path)) {

return path;

}

} catch {

// Ignore errors - CLI not in PATH

// Prevent PATH lookups from hanging indefinitely

timeout: 2000,

});

const path = result.trim().split('\n')[0];

if (path && existsSync(path)) {

return path;

}

} catch (error) {

// On timeout or lookup errors, treat as "CLI not in PATH"

return null;

Fixed in eaa681b - added 2-second timeout to prevent indefinite blocking on PATH lookups from network-mounted entries or misconfigured shell hooks.

src/utils/cli-locator.test.ts

+  it('should locate a Copilot CLI binary', () => {
+    const location = locateCopilotCli();
+
+    // Should find either bundled or system CLI
+    expect(location).toBeTruthy();
+
+    if (location) {
+      expect(location.path).toBeTruthy();
+      expect(['bundled', 'system']).toContain(location.source);
+      expect(location.version).toBeTruthy();
+    }


These tests assume a Copilot CLI binary is present on the machine running the test (expect(location).toBeTruthy()), which makes CI and contributor runs brittle (e.g., when optional deps are omitted, unsupported platform/arch, or --ignore-scripts/--omit=optional). Prefer mocking existsSync/execFileSync to unit test the resolution logic, or relax the assertion to only validate the shape when location is non-null.

Fixed in eaa681b - tests now handle null returns gracefully and only validate structure when CLI is found, making them CI-friendly for --omit=optional scenarios.

src/screens/home.tsx

+    // Load CLI info asynchronously
+    setCliInfo(getCliInfo());


This comment says "Load CLI info asynchronously", but getCliInfo() is synchronous and can perform blocking work (process execution) under the hood. Either update the comment to match reality or move the CLI lookup off the render path (e.g., defer via setTimeout/Promise.resolve().then(...) and then setCliInfo).

Suggested change

// Load CLI info asynchronously

setCliInfo(getCliInfo());

// Load CLI info asynchronously (off the initial render path)

Promise.resolve().then(() => {

setCliInfo(getCliInfo());

});

Fixed in eaa681b - moved CLI lookup off the render path using Promise.resolve().then() to defer the blocking work asynchronously.
