kshitijk4poor 4816646109 feat(web): parallel plugin — first async-extract plugin
Migrates Parallel.ai from inline `_parallel_search()` / `_parallel_extract()`
in tools/web_tools.py to a bundled plugin at plugins/web/parallel/.

First plugin in the codebase to expose an async :meth:`extract`:

  - search() is sync — Parallel.beta.search
  - extract() is **async def** — AsyncParallel.beta.extract

The ABC's docstring on supports_extract() already permits sync-or-async;
this commit is the first to exercise the async path. The web_extract_tool
dispatcher (next commit) detects coroutines via
inspect.iscoroutinefunction and awaits accordingly.

Behavior preserved:
  - PARALLEL_API_KEY required (raises ValueError if missing → surfaced
    as {"success": False, "error": "..."} instead)
  - PARALLEL_SEARCH_MODE env var honored (agentic|fast|one-shot, default
    agentic), validated via _resolve_search_mode()
  - Limit capped at 20 server-side via min(limit, 20)
  - Per-URL failure mode preserved: response.errors[] each become a
    result dict with an "error" field rather than raising
  - Module-level _parallel_client / _async_parallel_client caches kept
    (mirrors legacy singleton pattern)

Adds "parallel" to _WEB_PLUGIN_SKIPLIST in hermes_cli/tools_config.py so
the picker doesn't double-list.

The legacy inline _parallel_search, _parallel_extract, _get_parallel_client,
_get_async_parallel_client in tools/web_tools.py are NOT deleted yet — the
dispatcher still calls them. They go away when the dispatcher cuts over.

E2E verified:
  - inspect.iscoroutinefunction(p.search) -> False
  - inspect.iscoroutinefunction(p.extract) -> True
  - extract() returns a coroutine (not a list)
  - 5 providers register correctly (brave-free, ddgs, exa, parallel, searxng)
