Problem

The ASAN job in PR #369 failed during the regular parallel test phase before the sharded NP/LR tests ran:

• Failed run/job: https://github.com/Wire-Network/wire-sysio/actions/runs/27022195099/job/79758140462
• Symptom: multiple harness tests failed while importing wallet keys.
• ASAN signature from the job log:

ERROR: AddressSanitizer: stack-use-after-scope
...
CLI::App::add_option<std::string>(...)
...
clio wallet import --name ignition --private-key ...

clio registered CLI11 options backed by strings declared inside short wallet subcommand setup blocks. CLI11 keeps references to those option targets and invokes parse/callback logic after those blocks have exited, so ASAN correctly reports use-after-scope when wallet import writes to wallet_key_str.

Fix

Hoist the wallet subcommand option storage to the lifetime of the wallet command setup in main, covering:

• wallet import
• wallet remove_key
• wallet remove_name
• wallet create_key
• wallet set_key_name

This keeps the existing CLI behavior while ensuring CLI11 option targets outlive parse and callback execution.

Verification

• Configured a local build in build/clio-asan-fix.
• Built clio successfully:

cmake --build build/clio-asan-fix --target clio -- -j6

• Checked the affected command still parses help:

./build/clio-asan-fix/programs/clio/clio wallet import --help
