Subject: [PATCH 1/3] feat(deno): Export metrics API from Deno SDK

The metrics namespace is already exported from @sentry/core and re-exported
by @sentry/node, but was missing from the Deno SDK.

Subject: [PATCH 3/3] chore(deno): Ignore deno package in codecov and gitignore
 deno.lock

Deno tests run via Deno's native test runner, not vitest, so codecov
cannot see their coverage. Adding packages/deno/** to the codecov ignore
list prevents false coverage drops. Also gitignore deno.lock which is
generated when running deno test.
