refactor: rename debug-wttrin-* commands to wttrin-debug-* with obsolete aliases

The four interactive commands in `wttrin-debug.el` used `debug-wttrin-` as their prefix instead of the package's `wttrin-debug-` prefix. package-lint flags this as a convention violation, and it makes M-x discovery slightly less consistent for users.

Renamed:
- `debug-wttrin-show-raw`   -> `wttrin-debug-show-raw`
- `debug-wttrin-enable`     -> `wttrin-debug-enable`
- `debug-wttrin-disable`    -> `wttrin-debug-disable`
- `debug-wttrin-mode-line`  -> `wttrin-debug-mode-line`

The old names stay available as `define-obsolete-function-alias` entries marked since 0.4.0, so anyone with a keybinding or `(call-interactively 'debug-wttrin-enable)` in their config keeps working. The byte-compiler will emit an obsolescence warning to nudge migration. Aliases will be removed in a future release.

Internal caller `wttrin--debug-mode-line-info` now invokes the new name. Test files renamed to match (`test-debug-wttrin-*.el` -> `test-wttrin-debug-*.el`); inside each, ert-deftest names and function calls were updated.

Added `tests/test-wttrin-debug-aliases.el` to verify each old name resolves via `indirect-function` to the new name and carries `byte-obsolete-info` with the expected target and "0.4.0" version.

+;; The four `debug-wttrin-*' names were renamed to `wttrin-debug-*' in
+;; 0.4.0 to follow the package-prefix convention.  The old names remain
