discussed that fixers are broken, hard to get right, and low value even if fixed, feeding errors to agents is more flexible

🟢 Approval recommended
The narrowly scoped export removals disable unsafe fixes without changing diagnostic behavior, and the discovery regression covers the intended contract.
No open issues 🎉
What changed in this PR
Disables automatic TaskAnalyzer code fixes for the 18.13 release to avoid unsafe transformations, while preserving diagnostics and the existing fixer implementations and tests.
Changes:
- Removes discovery exports from both code-fix providers.
- Adds a regression test verifying that no code fixes are exported and all expected analyzers remain discoverable.
- Removes code-fix availability claims and documentation.

Context
The current fixes can produce uncompilable code, change path/parsing behavior, or break callers when retyping public properties. Disable them for the first release rather than ship unsafe transformations.
Changes Made
Remove both providers’ MEF exports and code-fix documentation. Keep implementations/tests and add a discovery regression.
Testing
Unit tests
