l0ng-aiandClaude 9d4e778c7b feat(settings): HTTP Proxy settings for the IDE's outgoing connections (#194)
* feat(settings): HTTP Proxy settings for the IDE's outgoing connections

Add Appearance & Behavior › System Settings › HTTP Proxy with three modes:
No proxy, Auto-detect proxy settings (the default; environment proxy as
before) and Manual proxy configuration (HTTP or SOCKS, host and port, a
comma-separated "No proxy for" list with `*` wildcards, optional proxy
authentication). "Check connection…" GETs a URL with the settings as edited
and reports the status or the error.

- ide-core: `ProxySettings` plus routing (no-proxy globs, loopback always
  direct, credentials percent-encoded), the current proxy for the process,
  curl arguments and child-process variables.
- ide-http: `client::build` / `client::shared` is the one HTTP client
  constructor; the HTTP Client requests and the update check go through it.
- ide-tools: curl downloads (tools, JDKs, debug adapters, agent registry,
  remote server) follow the setting.
- A manual proxy reaches child processes (language servers, debug adapters,
  terminals, git) as HTTP_PROXY / HTTPS_PROXY / ALL_PROXY / NO_PROXY.
- The proxy password is kept in the owner-only saved passwords file
  (`proxy-password.json` in the app data directory), not in settings.toml.
