fix(skill): update Parallel Search MCP endpoint

[georgeatparallel]

Type of Change

• Skill (dev) - adds a meta skill in .claude/skills/ (instructions for Claude Code)
• Skill (runtime) - adds/updates container/skills/ for the chat agent
• Fix - bug fix or security fix to source code
• Simplification - reduces or simplifies source code

Description

The existing add-parallel developer skill still points Search MCP at a retired host and names the old quick-search tool. This updates those two references to the current https://search.parallel.ai/mcp endpoint and web_search tool without changing the skill's setup flow or Task MCP guidance.

Validation:

• confirmed no retired Search MCP host or tool-name reference remains in the skill
• initialized the current endpoint without credentials and verified it exposes web_search and web_fetch
• ran git diff --check

The updated references were tested from a fresh checkout. The full setup skill was not run because it requires account credentials and mutates the local environment, container, and service configuration.

For Skills

• I have not made any changes to source code
• My skill contains instructions for Claude to follow (not pre-built code)
• I tested this skill on a fresh clone

Disclosure: I work at Parallel.ai, which operates this MCP endpoint.
