feat: add TokenProvider seam for per-request GitHub tokens (#1)

Replace construction-time github.WithAuthToken(cfg.Token) with a
per-request token resolution so callers can inject rotating credentials
(e.g. short-lived GitHub App installation tokens minted on demand by the
sneat-go backend) without rebuilding the adapter.

- Add TokenProvider interface { Token(ctx) (string, error) },
  TokenProviderFunc adapter and StaticTokenProvider(token).
- Add Config.TokenProvider field; an explicit provider wins over
  Config.Token, and a bare non-empty Config.Token is auto-wrapped in
  StaticTokenProvider, so existing callers keep working unchanged.
- Inject the token via a tokenProviderTransport RoundTripper that asks
  the provider on every request; provider errors abort the request and
  surface as regular operation errors. Caller-supplied http.Clients are
  copied, never mutated.
- Deduplicate the identical go-github client construction in
  NewGitHubFileReader and NewTreeWriter into newGitHubAPIClient.
- go.sum: add missing entries for dalgo v0.62.2 and golang.org/x/sys.

Design: sneat-co/backstage docs/roadmaps/ovdb-access-tokens-grants.md
(Decision 3.4, sequencing item 3).
