Add Neon, Linear, Sentry, and PostHog MCP servers

[saddlepaddle]

Summary

• Adds 4 MCP server configs to .mcp.json so all team members get access in Claude Code
• Neon, Linear, Sentry: native HTTP transport with OAuth (authenticate via /mcp in Claude Code)
• PostHog: uses mcp-remote bridge with Bearer token auth (requires POSTHOG_API_KEY env var)

Test plan

• Run Claude Code and verify /mcp shows all new servers
• Authenticate with each OAuth-based server (Neon, Linear, Sentry)
• Set POSTHOG_API_KEY in .env and verify PostHog connects

Summary by CodeRabbit

• New Features
  • Added integrations with Neon, Linear, and Sentry services for improved connectivity.
  • Added PostHog analytics integration with authenticated remote connector to enable secure event reporting and configurable API-key based auth.

🐰 I nibble on configs bright,
Four new servers in my sight—
Neon, Linear, Sentry hum,
PostHog answers with a drum.
Hoppity-hop, the MCPs unite!

In @.mcp.json:
- Line 15: The JSON key "Neon" is incorrectly cased and should be "neon" to
match the lowercase convention used by other server keys; rename the key "Neon"
to "neon" in .mcp.json and update any references/usages in the codebase that
access this key (search for "Neon" in config loaders, consumers, or tests) so
consumers of the config use the new lowercase symbol and avoid runtime lookup
failures.

27-38: Consider pinning mcp-remote to a specific version.

Using mcp-remote@latest means any breaking change in a new release could silently break the PostHog integration for the team. Pinning to a known-good version (e.g., mcp-remote@0.1.1) improves reproducibility.
