Add MCP server table

Currently it is difficult to audit what mcp servers are in use (specifically as configured in popular IDEs) and what options (in general - redaction is in play to attempt to not make poor auth situations worse by letting the SIEM find out about it) are used for connecting to them. We were using an augeus lens to parse the specific known json locations, but that's a bit clunky. This is otherwise a blind spot to know what's being used/pointed where and how many of those connections are following 'best practices' vs leaving auth on disk in plaintext 😅
The redaction process is imperfect as a known issue, but the feature works and the people who worked on this before I came along iterated on it a few times to clean out just about all failure cases we saw. We've only pushed it out to Macs is why it's Darwin-only, but linux should be relatively low-effort to add. There's an 'inert' feature hinted at about user being a column you can constrain by, but there's other things currently under-optimized we can address along with that in a subsequent planned PR... it involves bumping the osquery-go for a big fix, the newer micromdm/plist also bundles better error handling/result retention when an issue is encountered
It's a fair amount of code - 30 files changed, ~2k lines (plus over 1k lines of tests) added, we're moving/promoting golang.org/x/sys from indirect to direct as a dependency, (and I also have some ideas for additional schema/usage docs and such,) just checking if sounds like a reasonable thing to contribute as-is?

No specific files, tests, or entry points are named. Start by reviewing the existing Darwin-only MCP server implementation and its tests, then confirm the proposed schema, IDE configuration locations, redaction behavior, and Linux scope with the maintainers. Done should include the table, coverage for its connection options, and passing tests.
