Description

Refactor CLI documentation GIF tapes to reduce duplication and keep recording settings consistent.

• Add shared VHS snippets under docs/images/shared/ (base.tape for shell/theme/typing setup, git_init.tape, cleanup.tape).
• Update bump.tape, commit.tape, init.tape, shortcut_custom.tape, and shortcut_default.tape to Source those snippets instead of repeating the same preamble.
• Remove unused docs/images/bump.yml and docs/images/commit.yml.
