Copilot 241c6211d6 Fix build-and-report failure by removing unsupported default FStar HO-matching flag (#9748)
The `build-and-report` workflow failed in `build-and-report` because
FStar was invoked with a default `OTHERFLAGS` value containing
`--smt.ho_matching true`, which current FStar no longer recognizes. This
change removes that default while keeping the input configurable for
manual runs.

- **Root cause**
- Workflow default `fstar_otherflags` was set to `--smt.ho_matching
true`.
- During `make`, FStar exited with `error: unrecognized option
'--smt.ho_matching'` (job `79905082893`).

- **Workflow changes**
  - Updated `.github/workflows/fstar-master-build.yml`:
- `workflow_dispatch.inputs.fstar_otherflags.default` changed from
`--smt.ho_matching true` to `""`.
- Job env fallback `FSTAR_OTHERFLAGS` changed from `--smt.ho_matching
true` to `""`.
- Removed the outdated option example from the `fstar_otherflags` input
description.

- **Resulting behavior**
- Default scheduled/manual workflow runs no longer pass unsupported
FStar flags.
- Custom flags can still be provided via `fstar_otherflags` when needed.

```yaml
fstar_otherflags:
  description: "Extra FStar OTHERFLAGS"
  required: false
  default: ""

# ...
FSTAR_OTHERFLAGS: ${{ github.event.inputs.fstar_otherflags || '' }}
```
