zeekayandHanzo Dev 9a8b4b5c46 fix(cli): pip install hanzo shipped a 10-command CLI, not the 56-command one
`hanzo` depends on `hanzo-cli`, and BOTH declared `[project.scripts] hanzo`.
Entry-point resolution is install-order dependent, so which CLI a user got was
a coin flip — and hanzo-cli kept winning. The result:

  $ hanzo auth login
  Error: No such command 'auth'.

So the "auth login is broken by Cloudflare 1010" story was real but unreachable:
users never got as far as the HTTP call, because the binary they had did not
have an `auth` command at all. Publishing that fix would have changed nothing.

One command, one owner:
- hanzo-cli drops its console script. `hanzo` is the ONE command.
- `paas` and `bot` are mounted into it — the only two groups with no equivalent.
  `kms` is NOT mounted: `hanzo secrets` is a strict superset (audit/grant/
  revoke/rollback/rotate/versions on top of the same get/list/set/delete), and
  two commands for one concern is what we are removing.
- hanzo_cli grows a __main__ so it stays invocable as `python -m hanzo_cli`,
  and its e2e suite targets that instead of whatever `hanzo` resolves to.

Endpoints, one definition:
- models.IAMConfig (the class the package EXPORTS) gains the HIP-0111 endpoint
  properties. config.IAMConfig had them, but nothing imports that one — a
  second same-named class nobody uses is how the legacy path survived.
- config.py + fastapi.py stop hand-assembling paths and read the constants.
- password_login posted to `/oauth/token`, which is not a 404: IAM serves a
  200 text/html SPA catch-all for unregistered paths, so it received a login
  PAGE and json() blew up on HTML. Verified: legacy 200 text/html vs canonical
  401 application/json.

PKCE, because this is a public client:
- browser_login ships no client_secret, so the authorization code was the only
  secret in the flow and it arrives over a plaintext loopback redirect. The SDK
  already accepted code_challenge/code_verifier; the CLI simply never passed
  them. RFC 8252 §8.1 / RFC 7636 S256.

Version, one source:
- pyproject said 0.4.4, __init__ said 0.3.47, cli.py said 0.3.48, and the
  installed binary reported 0.1.0 — four answers, none right. Now resolved
  from the installed distribution.

Verified on a clean venv: entry-point providers 2 -> 1, commands 10 -> 58,
`hanzo --version` 0.1.0 -> 0.4.4, all four endpoints canonical. hanzo-iam
19/19 pass; hanzo-cli's 20 failures are unchanged before and after and are all
live-service auth (no stored token in this environment).

])

Memory Management

from hanzo.memory_manager import MemoryManager

memory = MemoryManager()
memory.add_to_context("user", "What is Python?")
memory.add_to_context("assistant", "Python is...")
context = memory.get_context()

Fallback Handling

from hanzo.fallback_handler import FallbackHandler

handler = FallbackHandler()
result = await handler.handle_with_fallback(
    primary_fn=api_call,
    fallback_fn=local_inference
)
