Fix index.md not being generated

Browse Source 
- Generate index even when no .org files are found
- Don't halt CLI early when no org files - let pipeline complete
- Index will be empty but present, allowing Quartz to serve something

### Tool Call [completed]: git add -A && git commit -m "Fix Quartz port not being passed correctly
When CLI options --port/--ws-port were not provided, nil values were
being explicitly passed to Server.start_link, which caused Keyword.get
to return nil instead of the default. Now we only include port options
in the keyword list if they have actual values."

## Agent (2026-02-21 21:50:19)
Fixed. The issue was that when CLI options `--port` and `--ws-port` weren't provided, the code was passing `port: nil` and `ws_port: nil` explicitly. `Keyword.get(opts, :port, default)` returns `nil` (not the default) when the key exists with a `nil` value.
Now only non-nil port values are included in the options passed to `Server.start_link`.

## Agent (2026-02-22 11:44:53)
I see the issue! When there are 0 org files (line 151-153), we return `:ok` early without generating an index. But more importantly, let me check what happens with the parallel export - maybe it's returning early on the `{:ok, 0}` case incorrectly.
Let me also check the export.ex parallel code more carefully:

The export looks fine. Let me run the actual build to see what's happening. First let me check what the actual content_dir is and if index.md exists there:

## Agent (2026-02-22 11:45:12)
There are no `.org` files in `notes/`. Let me check if there are any org files elsewhere, or if the content was previously in a different form:

./README.org
```
## Agent (2026-02-22 11:45:15)
There's only the README.org. So the actual issue is that when there are no org files to export, the index.md isn't being generated. Let me trace through the pipeline:
1. In `server.ex:run_initial_pipeline`, when `export_all` returns `{:ok, 0}`, we just return `:ok` without calling `OrgGarden.Index.generate`
Let me also check the CLI flow since you might be running the CLI directly:

## Agent (2026-02-22 11:45:22)
I see the problem! In the CLI's `export_all` function (line 308-310), when there are 0 org files, it calls `System.halt(0)` immediately - it doesn't even get to run transforms or generate the index!
But wait, you said index.md is missing. Let me check if there ARE org files being exported but the index isn't being generated. Let me trace the full serve flow:

I see - for `build` command, `generate_index` is called (line 141), but the problem is `export_all` on line 139 might call `System.halt(0)` before we get there if no org files exist.
Let me look at where serve mode handles this:

For `serve`, it delegates to `OrgGarden.Server` which calls `run_initial_pipeline`. The problem there is that when `{:ok, 0}` is returned, index is not generated.
Let me fix both issues:
1. In `server.ex`: Generate index even when there are 0 org files
2. In `cli.ex`: Don't halt immediately when 0 org files - let the pipeline continue
