Subject: [PATCH] ci: skip typecheck for refs and non-code file PRs (#3624)

Follow-up to #3615. The `code` filter currently fires typecheck for any
change outside `docs/`, `.changeset/`, `hosting/`, or `.github/` - so a
docs-only PR like #3623 (touching `references/ai-chat/.env.example` +
`README.md`) triggered the typecheck job. None of the `references/*`
packages declare a `typecheck` script either, so even when a real code
change lands there, `turbo run typecheck` skips them. Running the job is
pure cost.

Tightens the filter to also exclude:

- `references/**` - playground projects, none of them contribute to
`turbo run typecheck` today
- `**/*.md` - markdown anywhere
- `**/.env.example` - example env files anywhere

Two known gaps left open:

- references/ have no real CI typecheck coverage. Separate question -
either add `typecheck` scripts to each (or top-level `tsc -p`), or
accept playground status.
- `changes` job still runs (it's a path-filter step) but the dependent
jobs all skip on irrelevant PRs.
