task: migrate infrahubctl CLI from Typer to Cyclopts

[dgarros]

Component

• infrahubctl CLI

Need

The infrahubctl CLI is built on Typer, which has
no native support for async command handlers. To work around this we maintain our own
AsyncTyper subclass (infrahub_sdk/async_typer.py) that wraps every async command in
asyncio.run. This is a local shim we have to keep working across Typer releases, and
Typer itself has seen limited maintenance activity.

The ask is to migrate the CLI to Cyclopts so
that:

• The locally-maintained AsyncTyper shim can be removed — Cyclopts supports async
  command handlers natively.
• The project depends on a more actively maintained CLI framework for better long-term
  support.
• Startup can benefit from Cyclopts' lazy import of subcommands, reducing CLI overhead.

Context

• The local shim lives in infrahub_sdk/async_typer.py (AsyncTyper(Typer)).
• Typer / AsyncTyper is used broadly across the CLI — roughly two dozen modules under
  infrahub_sdk/ctl/ import typer or AsyncTyper (commands, parameters, parsers,
  and the object/ subcommands), so this is a wide surface, not a single entry point.
• typer>=0.15.0 is currently pinned in pyproject.toml (declared in two dependency
  groups).
• Ruff carve-outs exist specifically for Typer patterns (B008 for typer.Option in
  defaults, DOC501 for typer.Exit/Abort as control flow) — these will need
  revisiting as part of the migration.
