Remove TaprootChannelSigner

We plan to have a single channel signer type going forward, so this is
unnecessary.

The short version

What changed, and why it matters

This commit removes an unfinished Taproot-specific signer type from the Lightning Dev Kit codebase. The removed code was behind a special compile-time flag ('taproot') and consisted almost entirely of placeholder 'todo!()' stubs that did not actually sign anything. The change is a cleanup/refactoring step toward having one unified channel signer type, not a security fix.

Recommended action

No security action required. Treat as a normal API-cleanup commit. Downstream users building with the non-default 'taproot' feature should expect compile-time breakage and should migrate to the unified EcdsaSigner/InMemorySigner channel signer interface.

Security signals we found

01

No security-relevant code paths are altered: all removed Taproot branches were todo!() stubs unreachable in normal builds.

02

No bug fixes, bounds checks, input validation, or cryptographic hardening are present in the diff.

03

The commit message frames the change as architectural simplification, not a vulnerability remediation.
