beyondkmp 1161141d00 refactor(agents): replace postinstall patch with SDK's spawnClaudeCodeProcess option (#13886) ...

### What this PR does

Before this PR:
The Claude Agent SDK's minified `sdk.mjs` was patched at `postinstall`
time via regex-based replacements (`scripts/patch-claude-agent-sdk.ts`)
to convert `spawn` to `fork` with IPC stdio. This broke on every SDK
version bump when variable names changed.

After this PR:
Uses the SDK's built-in `spawnClaudeCodeProcess` option (available since
v0.2.81) to provide a custom `fork()`-based process spawner, eliminating
the need for any postinstall patching.

### Why we need it and why it was done in this way

The following tradeoffs were made:
- We handle stderr ourselves in the custom spawner because the SDK only
reads stderr inside its internal `spawnLocalProcess()`, not when
`spawnClaudeCodeProcess` is provided.

The following alternatives were considered:
- Keeping the postinstall patch: rejected because it's fragile and
breaks on SDK updates.
- Using `spawn` with explicit `node` path: rejected because `fork()`
automatically uses `process.execPath` which works reliably in both dev
and packaged Electron (where `node` may not be on PATH).

### Breaking changes

None.

### Special notes for your reviewer

- `fork()` with `ELECTRON_RUN_AS_NODE=1` makes the Electron binary act
as Node.js, which is the same behavior the postinstall patch achieved.
- The IPC channel (`'ipc'` in stdio) is added for safety/compatibility
but isn't actively used by the SDK protocol (confirmed by searching the
minified source for `.send()` and `on('message')` on the process object
— zero hits).
- Net deletion of ~600 lines.
