I got carried away with Gemini and basically rewrote CI and the release
process for the new LLM reality. This work was largely completed by
Gemini.
- Bump all SDK versions to the current beta (3.9.0-0)
- Run `flutter channel beta`
- Wrote `ci_script.dart` to replace the bash scripts
- Converted repository to pub workspace #2499
- Added llm.md and release.md
- Added redirect for deprecated Samples Index

No functional changes, just cleanup.
Updating the build_value build dependencies then regenerating allows us
to remove the analysis excludes in the `analysis_options.yaml` files due
to them now ignoring lints.
Change the deprecated use of `TextButton` to `HyperlinkButton` in
`fluent_ui` sample.
The error was:
```
Analyzing fluent_ui...
info - lib/src/widgets/photo_details.dart:40:45 - 'TextButton' is deprecated and shouldn't be used. Deprecated in 4.4.3. Use HypelinkButton instead. Try replacing the use of the deprecated member with the replacement. - deprecated_member_use
