test(recording): add a script to schedule recording workflow (#3170)

See comment here:
https://github.com/llamastack/llama-stack/pull/3162#issuecomment-3192859097
-- TL;DR it is quite complex to invoke the recording workflow correctly
for an end developer writing tests. This script simplifies the work.

No more manual GitHub UI navigation!

## Script Functionality

  - Auto-detects your current branch and associated PR
  - Finds the right repository context (works from forks!)
  - Runs the workflow where it can actually commit back
  - Validates prerequisites and provides helpful error messages

## How to Use

First ensure you are on the branch which introduced a new test and want
it recorded. **Make sure you have pushed this branch remotely, easiest
is to create a PR.**

```
  # Record tests for current branch
  ./scripts/github/schedule-record-workflow.sh

  # Record specific test subdirectories
  ./scripts/github/schedule-record-workflow.sh --test-subdirs "agents,inference"

  # Record with vision tests enabled
  ./scripts/github/schedule-record-workflow.sh --run-vision-tests

  # Record tests matching a pattern
  ./scripts/github/schedule-record-workflow.sh --test-pattern "test_streaming"
```

## Test Plan

Ran `./scripts/github/schedule-record-workflow.sh -s inference -k
tool_choice` which started
4820409329
which successfully committed recorded outputs.
