The --type filter was concatenated into ImmutableKeywords in
SearchQueryBuild, which bypassed search.Query's quoting and let values
that contained quotes (or extra qualifiers) corrupt the final query.
Per babakks's suggestion in the review thread, model it as a regular
qualifier instead.
Add an IssueType field to Qualifiers tagged `qualifier:"type"` so it
shares a key with the existing Type field, and rework Qualifiers.Map
to honour the tag and concatenate values when multiple fields share
the same key. SearchQueryBuild now drops its bespoke type:X
formatting and just sets Qualifiers.IssueType, leaving the
keyword/qualifier escaping to pkg/search.

Enables Copilot to be requested as a pull request reviewer, supporting both interactive and non-interactive flows. Introduces new reviewer search functionality, updates reviewer partitioning to distinguish users, bots, and teams, and adds a GraphQL mutation for reviewer management on github.com. Updates help text, tests, and internal APIs to support Copilot reviewer login and display names, while maintaining compatibility with GitHub Enterprise Server.
Thanks to @bagtoad, this commit refactors the argument to `NewCopilotReplacer(bool)` from being where this is used to what it effect is has.
Because there is already precedence for display name being `<login> (<name>)`, I worried there would be confusion for `Copilot (AI)` being display name for assignees and reviewers but `Copilot` when going to GitHub.com UI. Instead, I renamed the argument based on whether the login is returned / replaced.
This commit is primarily focused on fixing the existing `gh issue create` tests with the changes to the underlying queries retrieving the data for resolving metadata.
Additionally, a new test case for `gh issue create --web --assignee @copilot` was added to mirror existing tests. While exercising this capability, I found out the web UI apparently wants `copilot` instead of the `copilot-swe-agent` login, so changes to address that were a part of this commit.
