Addressed the same-repository issue requirement: I created #297 and updated this PR to link it with Closes #297, while retaining warpdotdev/warp#12321 as the upstream request.

Issue #297 is now undergoing Oz triage and awaiting the maintainer-applied ready-to-implement label. I will re-trigger /oz-review once that readiness gate is satisfied.

Overview

This PR adds a git read-tree command signature with options and a variadic tree-ish argument generator.

Concerns

• The option list does not cover all valid documented git read-tree forms: --recurse-submodules is missing its optional =<checkout> value, and --exclude-per-directory <gitignore> is omitted entirely.
• No security concerns found in this JSON-only command-signature change.
• No approved spec context was provided for additional implementation-vs-spec validation.

⚠️ [IMPORTANT] git read-tree accepts --recurse-submodules[=<checkout>]; add an optional argument for the =<checkout> form so valid submodule-control completions are not omitted.

[oz-for-oss]

⚠️ [IMPORTANT] The documented --exclude-per-directory <gitignore> option is missing from this options array, so the new signature does not cover the available read-tree flags.
