pub fn install_bundled_cli() -> Option<PathBuf>Expand description
Returns the path to the bundled Copilot CLI, extracting it from the embedded archive on first call.
This is the same path Client::start resolves to when
ClientOptions::program is CliProgram::Resolve, no
COPILOT_CLI_PATH override is set, and no
ClientOptions::bundled_cli_extract_dir is configured — exposing
it directly so callers (health checks, diagnostics, version probes)
can reach the bundled binary without spinning up a full Client.
Subsequent calls return the cached result. Extraction is skipped when the target file already exists.
Returns None when the bundled-cli feature is off, the target
platform isn’t supported by build.rs, or extraction failed (the
failure is logged via tracing::warn!). When None is returned for
the “feature off” reason, HAS_BUNDLED_CLI is also false.
This deliberately does not fall back to the build-time-extracted
dev-cache path used when bundled-cli is off — callers that want
that resolution should continue to use CliProgram::Resolve.
