v0.8.32 — install leaves servers reachable; call flags order-insensitive

Fixed

• mcptoon install now makes the server reachable (issue #36). install answered
  {"status": "installed", …} and then the server was nowhere: it did not appear in
  mcptoon list, and mcptoon call <server> <tool> returned UNKNOWN_SERVER. The
  command only wrote a generated handler module into the state dir plus a record in
  ~/.mcp-cli/pro_installed.json. Nothing ever imported that module — the package
  contains no loader — so router._HANDLERS stayed empty, and the config, the
  only store list and call read, was never touched. install now registers the
  server in the user's config (transport: http for URL installs, stdio with
  command/args otherwise), so the server shows up in list and is callable.
  install --remove takes the config entry back out and reports it as
  config_removed. Every property above has a regression test. Reported by @examosa,
  who traced it into router.py instead of only reporting the symptom.
• mcptoon call --destructive works before the positionals (issue #37).
  mcptoon call --destructive <server> <tool> fed the flag in as the server name
  and failed with UNKNOWN_SERVER, while the identical flag placed after the
  positionals worked. --destructive was the one call-level option not stripped
  before the positionals were read (--envelope, --stdin, --input-responses,
  --request-state and --auto already were). It is now stripped with the others,
  so option order no longer changes the outcome, and call --destructive <server>
  reports usage instead of reading the server name as the tool. inspect and list
  were never affected. Reported by @examosa, with a reproduction in both orders.

Removed

• The generated-handler subsystem. With install registering into the config, the
  per-server handler modules were dead weight — written by install and update,
  imported by nobody. They are no longer generated, and mcptoon install --remove
  still deletes a file left by ≤ 0.8.31 so an upgraded machine does not keep stale
  modules. This removes a code-generation primitive instead of mitigating it: the
  0.8.29 hardening of those modules defended files that never executed. An install
  writes no Python to disk at all now.
