This reverts commit 9e488a64668a3a25db9a09f4266cbdf2d4afdc6f.
What changed, and why it matters
This commit simply removes a developer-only experimental feature flag called 'dev_uniform_padding' from an internal message definition file. It is a clean revert of a previous commit that added the flag. There is no indication this change fixes or introduces a security vulnerability; it just undoes an unmerged or unwanted development experiment related to padding network messages for traffic-analysis defense.
No security action required. Treat as ordinary development cleanup. If the padding feature is desired, it should be reintroduced through normal design review rather than as a hidden dev flag.

No functional code changes or vulnerability indicators in the diff
Evidence from the diff
The diff removes two lines from connectd/connectd_wire.csv: a comment describing ‘dev_uniform_padding’ as padding outgoing messages to uniform 1460-byte segments for traffic-analysis defense, and the corresponding msgdata boolean field in connectd_init. This is a wire-protocol schema revert with no functional code changes shown. The feature was clearly marked ‘dev_’ (developer-only) and the commit message is a straightforward revert.
