remove: deprecated show command from CLI

The `show` command (`lore show issue 42` / `lore show mr 99`) was
deprecated in favor of the unified entity commands (`lore issues 42` /
`lore mrs 99`). This commit fully removes the command entry point:

- Remove `Commands::Show` variant from clap CLI definition
- Remove `Commands::Show` match arm and deprecation warning in main.rs
- Remove `handle_show_compat()` forwarding function from robot_docs.rs
- Remove "show" from autocorrect known-commands and flags tables
- Rename response schema keys from "show" to "detail" in robot-docs
- Update command descriptions from "List or show" to "List ... or
  view detail with <IID>"

The underlying detail-view module (`src/cli/commands/show/`) is
preserved — its types (IssueDetail, MrDetail) and query/render
functions are still used by `handle_issues` and `handle_mrs` when
an IID argument is provided.
