feat(cli): display custom profile alias names in profile list/show (#40371)

profile list and profile show assumed the wrapper script is always named
after the profile (wrapper_dir / name). When a custom alias exists — e.g.
`hermes profile alias steve --name qiaobusi` creates ~/.local/bin/qiaobusi
pointing at `hermes -p steve` — the display silently showed the profile
name (or nothing) instead of the alias the user actually typed.

The custom-alias *creation* path (create_wrapper_script(name, target)) was
added later; the *display* path was never updated to match.

Add find_alias_for_profile() — a reverse lookup that scans the wrapper dir
for our own wrappers (alias-named file containing 'hermes -p <profile>'),
prefers a custom alias over the profile-named one, strips .bat on Windows,
and sorts for deterministic output. Populate ProfileInfo.alias_name and wire
it into the three display sites (profile describe, list, show).

Credit: salvages the intent of #11506 by wss434631143, reimplemented on
current main against the post-#11506 custom-alias (--name/target) mechanism.

Tests: 6 new (profile-named, custom-name, none, unrelated-file rejection,
windows .bat strip, list_profiles surfacing). All 123 in test_profiles pass.
E2E verified against the real CLI for both custom and profile-named aliases.
