## Summary
Fixes #19782.
The `?` operator in `std/uri` was silently overwriting any query string
already present in the URI. This PR makes it append instead — which
matches the docstring ("Concatenates the query parameters") and the
natural expectation when chaining operations.
**Before:**
```nim
let u = parseUri("https://example.com/foo?existing=1") ? {"bar": "qux"}
echo $u # https://example.com/foo?bar=qux (existing=1 lost)
```
**After:**
```nim
let u = parseUri("https://example.com/foo?existing=1") ? {"bar": "qux"}
echo $u # https://example.com/foo?existing=1&bar=qux
```
## Changes
- `lib/pure/uri.nim`: fix `?` to append with `&` when a query string
already exists; add example to `runnableExamples`
- `tests/stdlib/turi.nim`: two new test cases (append to existing query,
empty params preserve existing)
- `changelog.md`: entry under Standard library changes
## Notes
I work with Claude as a co-processor. I'm 56, came to programming late,
and this is genuinely how I learn and contribute. I understand what I'm
submitting, but I didn't write it alone. If your project prefers
human-only contributions, just say so and I'll close without friction.

(cherry picked from commit b6842c144d)
This directory contains the test cases.
Each test must have a filename of the form: t*.nim
Note: Testament is only aware of tests under a directory (eg tests/foo/) and will ignore
top-level tests like tests/tbar.nim.
Specs
Each test can contain a spec in a discard """ ... """ block.
Check out the parseSpec procedure in the specs module for a full and reliable reference
action
Specifies what action this test should take.
Default: run
Options:
compile- compiles the module and fails the test if compilations fails.run- compiles and runs the module, fails the test if compilation or execution of test code fails.reject- compiles the module and fails the test if compilation succeeds.
There are certain spec keys that imply run, including output and
outputsub.
Categories
Each folder under this directory represents a test category, which can be
tested by running koch tests pcat <category> (or cat to avoid parallel
testing, which is slower).
The folder dll contains simple DLL tests.
The folder realtimeGC contains a test for validating that the realtime GC
can run properly without linking against the nimrtl.dll/so.
