Prepare v1.0.4 release

[T313C0mun1s7]

Summary

Prepare package metadata for publishing sm-logtool v1.0.4.

What changed

• Bump pyproject.toml project version from 1.0.3 to 1.0.4.
• Bump sm_logtool.version from 1.0.3 to 1.0.4.
• Confirm no remaining tracked 1.0.3, 1.0.2, 1.0.1, or 1.0.0 references exist in searched code/docs paths.

Why

This aligns tracked package version metadata before publishing the keyboard activation hotfix from PR #107.

Expected result

Builds and --version metadata report 1.0.4 once this release-prep branch is merged.

Scope

Release preparation only. Includes the already-merged Delivery lookup keyboard activation fix from PR #107 in the upcoming v1.0.4 release.
