This pull request primarily adds support for new "Think" agent message type.

Pull request overview

This PR appears to prepare the repo for a Fern SDK regeneration by “freezing” the current manually-patched versions of several generated files (as *.bak) and updating .fernignore to point at those backups.

Changes:

• Added *.bak copies of several previously patched Fern-generated files (socket clients, listen types, listen clients).
• Added *.bak copies of WireMock mappings and a Wire test file used in the wiremock-based suite.
• Updated .fernignore entries to ignore the .bak paths (temporarily freezing them during regeneration).

These newly added src/deepgram/**.py.bak files live inside the published deepgram package directory (see pyproject.toml package include config). With no packaging excludes configured, they are likely to be shipped in the wheel/sdist. If these backups are intended to be temporary for regeneration, consider keeping them outside src/ or adding an explicit packaging exclude for *.bak, and make sure they’re removed before merging/releasing.

PR description says this adds support for the new "Think" agent message type, but the only functional change here is swapping .fernignore entries to point at .bak backups (plus adding those backup files). If this PR is just the "prepare repo for regeneration" step, please update the PR description/title accordingly and ensure a follow-up commit in this PR restores .fernignore to the real paths and removes the .bak files before merging; otherwise this PR won’t actually deliver the stated feature support.
