feat(cli): add dynamic shell completion for bash, zsh, and fish

Replaces the hardcoded completion stubs in profiles.py with a dynamic
generator that walks the live argparse parser tree at runtime.

- New hermes_cli/completion.py: _walk() recursively extracts all
  subcommands and flags; generate_bash/zsh/fish() produce complete
  scripts with nested subcommand support
- cmd_completion now accepts the parser via closure so completions
  always reflect the actual registered commands (including plugin-
  registered ones like honcho)
- completion subcommand now accepts bash | zsh | fish (fish requested
  in issue comments)
- Fix _SUBCOMMANDS set: add honcho, claw, plugins, acp, webhook,
  memory, dump, debug, backup, import, completion, logs so that
  multi-word session names after -c/-r are not broken by these commands
- Add tests/hermes_cli/test_completion.py: 17 tests covering parser
  extraction, alias deduplication, bash/zsh/fish output content,
  bash syntax validation, fish syntax validation, and subcommand
  drift prevention

Tested on Linux (Arch). bash and fish completion verified live.
zsh script passes syntax check (zsh not installed on test machine).
