feat(sentry): add Sentry provider with configurable API base URL

[artile]

Adds a Sentry provider with a Project resource. The API base URL is part of the credentials, so one provider drives both Sentry SaaS and a self-hosted instance — the v1 provider hardcoded https://sentry.io/api/0.

const project = yield* Sentry.Project("api", {
  organization: "my-org",
  team: "backend",
  name: "API",
  platform: "node",
});

SENTRY_AUTH_TOKEN=...                                   # required
SENTRY_API_BASE_URL=https://sentry.example.com/api/0    # self-hosted, defaults to sentry.io

Follows #1001. Requests go through HttpClient directly because distilled has no sentry package. If you would rather see @distilled.cloud/sentry generated from Sentry's OpenAPI schema first, I will rebuild this on top of it.

This should be a distilled SDK: https://github.com/alchemy-run/distilled

cc @Mkassabov can you help?

Requested distilled SDK from this review comment:

alchemy-run/distilled#524 — @distilled.cloud/sentry generated from Sentry's first-party OpenAPI (getsentry/sentry-api-schema).
