This PR refactors the test workflow by consolidating individual test entries into comma-separated groups to streamline test execution in workflows and scripts.  
- Merges separate test items into grouped strings for float conversion tests  
- Consolidates test cases for float and integer conversions, as well as arithmetic and comparison operations

`14-22`: **Loop over tests with clear patterns.**
The new `for` loop correctly iterates through each test name. The regex branches maintain the original behavior. Consider refactoring the conditional chains into a `case` statement for enhanced readability and maintainability:
```bash
case "$TEST_NAME" in
  *_to_[iu]64)
    "$ROOT/bin/testfloat_gen" -level 2 -seed "$SEED" -rminMag "$TEST_NAME" | \
      go run ./internal/cmd/float_test "$TEST_NAME"
    ;;
  f?(16|32|64|128)_to_f?(16|32|64|128))
    "$ROOT/bin/testfloat_gen" -level 2 -seed "$SEED" "$TEST_NAME" | \
      go run ./internal/cmd/float_test "$TEST_NAME"
    ;;
  *)
    "$ROOT/bin/testfloat_gen" -seed "$SEED" "$TEST_NAME" | \
      go run ./internal/cmd/float_test "$TEST_NAME"
    ;;
esac
```
This keeps behavior identical while improving clarity.

**Correct test matrix entry typo.**
The first test group is missing the leading `f` in `f16_to_f64`, causing the runner to receive `16_to_f64` instead of `f16_to_f64`.  

Apply this diff to fix the typo:

<summary>🧩 Analysis chain</summary>

**Verify grouping aligns with script splitting logic.**
You've consolidated multiple tests into comma-separated strings. Ensure that `scripts/run_test.sh` correctly splits on *all* commas so each test is executed individually. Otherwise, only the first comma is handled, and subsequent tests will be lumped together.  

To reproduce the current behavior and its limitation, you can run:

Expect 3 elements (`a`, `b`, `c`), but current code yields only 2 (`a`, `b,c`).  
Please confirm or adjust the script accordingly.

---

🏁 Script executed:

```shell
#!/bin/bash
# Demonstrate splitting on only the first comma
arg="a,b,c"
arr=(${arg/,/ })
printf "Count: %d\n" "${#arr[@]}"
printf "%s\n" "${arr[@]}"
```

Length of output: 92

---

🏁 Script executed:

```shell
#!/bin/bash
set -e

echo "Listing contents of scripts directory:"
ls scripts || echo "scripts directory not found"
echo

if [[ -f scripts/run_test.sh ]]; then
  echo "Found scripts/run_test.sh, displaying first 200 lines:"
  sed -n '1,200p' scripts/run_test.sh
  echo
  echo "Searching for comma-splitting logic (IFS or /,/) in scripts/run_test.sh:"
  grep -nE 'IFS|/,/' scripts/run_test.sh || echo "No IFS or /,/ patterns found"
else
  echo "Error: scripts/run_test.sh not found"
  exit 1
fi
```

Length of output: 1258

---



</details>

**Fix comma-splitting in scripts/run_test.sh**  
The current line  
```bash
TEST_NAMES=(${1/,/ })
```  
only replaces the *first* comma, so an argument like  
```
"f16_to_f32,f32_to_f64,f64_to_f128"
```  
yields two items (`f16_to_f32` and `f32_to_f64,f64_to_f128`) instead of three.  

Please update the splitting logic so *all* commas become delimiters. For example:  
```diff
--- a/scripts/run_test.sh
+++ b/scripts/run_test.sh
@@ -6,7 +6,8 @@ set -eux
 
 SEED=${GITHUB_RUN_ID:-$(date +%s)}
 echo "$SEED"
-# shellcheck disable=SC2206

+
+# Option B: more robust with IFS
+# IFS=',' read -ra TEST_NAMES <<< "$1"
 
 ROOT=$(cd "$(dirname "$0")"; cd ..; pwd)
 cd "$ROOT"
```  
With this change, each comma‐separated test name in the workflow will be executed individually.

**Fix splitting of comma-separated test names.**
Using `${1/,/ }` replaces only the first comma, so multi-test groups with more than two entries won’t split correctly. Replace with global substitution or use `IFS` for full splitting. For example:
```diff
-# shellcheck disable=SC2206
-TEST_NAMES=(${1/,/ })
+# shellcheck disable=SC2206
+TEST_NAMES=(${1//,/ })
```
Or alternatively:
```bash
IFS=',' read -r -a TEST_NAMES <<< "$1"
```
This ensures each comma is converted to a separator, yielding one array element per test name.

## Walkthrough

The updates consolidate the GitHub Actions test matrix by grouping related test names into comma-separated strings, reducing the number of matrix entries. Correspondingly, the test execution script is modified to accept and process multiple test names separated by commas, iterating over each and applying the existing logic for running tests. No changes were made to public or exported interfaces, and only internal script variables and control flow are affected.

## Changes

| .github/workflows/test.yaml               | Consolidated individual test matrix entries into grouped, comma-separated test name strings for efficiency.     |
| scripts/run_test.sh                       | Updated to parse and process multiple test names from a comma-separated string, iterating over each test name.  |

## Poem

> In the warren, tests once hopped alone,  
> Now they leap together, as a group they’ve grown.  
> Scripts now handle a bunny parade,  
> Each test name in turn, no rabbit afraid!  
> With commas to guide them, they run down the trail—  
> A warren of tests, swift and never frail.  
> 🐇✨

### Chat

There are 3 ways to chat with [CodeRabbit](https://coderabbit.ai?utm_source=oss&utm_medium=github&utm_campaign=shogo82148/floats&utm_content=74):

- Review comments: Directly reply to a review comment made by CodeRabbit. Example:
  - `I pushed a fix in commit <commit_id>, please review it.`
  - `Generate unit testing code for this file.`
  - `Open a follow-up GitHub issue for this discussion.`
- Files and specific lines of code (under the "Files changed" tab): Tag `@coderabbitai` in a new review comment at the desired location with your query. Examples:
  - `@coderabbitai generate unit testing code for this file.`
  -	`@coderabbitai modularize this function.`
- PR comments: Tag `@coderabbitai` in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  - `@coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.`
  - `@coderabbitai read src/utils.ts and generate unit testing code.`
  - `@coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.`
  - `@coderabbitai help me debug CodeRabbit configuration file.`

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.

### CodeRabbit Commands (Invoked using PR comments)

- `@coderabbitai pause` to pause the reviews on a PR.
- `@coderabbitai resume` to resume the paused reviews.
- `@coderabbitai review` to trigger an incremental review. This is useful when automatic reviews are disabled for the repository.
- `@coderabbitai full review` to do a full review from scratch and review all the files again.
- `@coderabbitai summary` to regenerate the summary of the PR.
- `@coderabbitai generate docstrings` to [generate docstrings](https://docs.coderabbit.ai/finishing-touches/docstrings) for this PR.
- `@coderabbitai generate sequence diagram` to generate a sequence diagram of the changes in this PR.
- `@coderabbitai resolve` resolve all the CodeRabbit review comments.
- `@coderabbitai configuration` to show the current CodeRabbit configuration for the repository.
- `@coderabbitai help` to get help.

### Other keywords and placeholders

- Add `@coderabbitai ignore` anywhere in the PR description to prevent this PR from being reviewed.
- Add `@coderabbitai summary` to generate the high-level summary at a specific location in the PR description.
- Add `@coderabbitai` anywhere in the PR title to generate the title automatically.
