fix(craft): use regex pattern for binary artifact matching (#230)

## Summary

Fixes the broken `curl` install (`curl https://cli.sentry.dev/install |
bash`) which 404s because 0.9.0 shipped without platform binaries.

## Root Cause

Craft's `patternToRegexp()` treats plain strings as **exact matches**,
escaping `*` to `\*`. The pattern `'sentry-*'` in `.craft.yml` became
`/^sentry\-\*$/` — matching only the literal string `"sentry-*"`, not
actual artifact names like `sentry-linux-x64`.

Only `gh-pages` and `npm-package` (exact name matches) were downloaded
and uploaded to the GitHub release. All 5 platform binaries were
silently skipped.

## Fix

Use Craft's regex syntax (`'/^sentry-.*$/'` with enclosing slashes) so
the pattern is parsed as an actual regex.

This was introduced in #215 when migrating from `requireNames` (which
used proper regex `/^sentry-.+$/`) to the new `artifactProvider` config.
