07439f5f - shell: expand tildes in backtick commands with REPL completion support

shell: expand tildes in backtick commands with REPL completion support Implement `~` and `~username` expansion in backtick command literals, matching the behavior of POSIX shells. Tilde at the start of a word is expanded via `expanduser` at parse time; mid-word or quoted tildes are left as-is. Add REPL tab-completion for tilde paths in backtick and shell mode contexts: bare `~` completes to `~/` plus `~name/` for real local users, while `~/prefix` completes paths in the home directory keeping the contracted tilde form. Refactor `parse_dollar_interp` as a local function taking `st` as an explicit argument to avoid closure boxing of outer variables. Remove the now-redundant `expanduser` call in `repl_cmd`, since `shell_parse` handles tilde expansion at parse time. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
