To archive the old beaviour add the --output-raw option to your cli call

- utils/generic.py: narrow the broad except in execute_exists() so it
  no longer swallows typer.Exit. Since typer.Exit subclasses
  RuntimeError/Exception, resolve_database()'s print_error_and_exit()
  call (e.g. for an unknown --database name) was being re-caught and
  produced a spurious extra "Exit:" line after the real error message.
- utils/generic.py: replace the attribute_name[:-1].capitalize()
  depluralization with an explicit SINGULAR_NAMES mapping, since
  stripping one character mangled "processes" into "Processe" instead
  of "Process".
- utils/generic.py: add the missing `# pylint: disable=redefined-builtin`
  on `from rich import print`, matching project convention and fixing
  the CI pylint failure.
- main.py, commands/process.py: switch `from typing_extensions import
  Annotated` to the stdlib `from typing import Annotated`, matching
  the other command modules. Newer typer releases (needed after
  loosening the typer version constraint on main) no longer pull in
  typing_extensions transitively, so the old import broke on a fresh
  install.
- tests: update test_cmd_cubes.py, test_cmd_subset.py and
  test_cmd_view.py assertions for the new pretty-printed output and
  add --output-raw coverage, mirroring the pattern already used in
  test_cmd_dimension.py. Closes the "Update all tests" item from the
  PR description.
- README.md: document the new --output-raw flag. Closes the "Update
  readme" item from the PR description.

Verified: full mocked test suite (19/19) and pylint (10.00/10) pass
on a fresh install of the branch's dependencies.
