Restore executable bit on edited scripts

[wnstfy]

Summary

Follow-up to the dead-code cleanup PRs (#12, #13, #14). Those edits rewrote several files through a temp file (sed ... > tmp && mv tmp file), which silently dropped the executable bit (755 → 644) on files that were originally executable.

This restores the original mode on the five affected files:

• install.sh
• lib/core.sh
• lib/crypto.sh
• lib/generators.sh
• lib/schedule.sh

Details

• Mode-only change — zero content diff.
• Functionally cosmetic: the lib/*.sh modules are sourced, not executed, and install.sh is run via curl … | bash. But the inconsistency with the rest of the tree (e.g. backup.sh, verify.sh, setup.sh are 755) is unintended, so this puts them back.
• Files that were already 644 before the cleanup (history.sh, jobs.sh, migration.sh, restic.sh) are left as-is.

Testing

No code change. git diff shows only mode change 100644 => 100755 for the five files.

Greptile Summary

This is a mode-only follow-up to the dead-code cleanup PRs (#12–#14), restoring the executable bit (755) on five shell scripts whose permissions were silently dropped to 644 by the sed … > tmp && mv tmp file pattern used in those PRs.

• install.sh, lib/core.sh, lib/crypto.sh, lib/generators.sh, and lib/schedule.sh each have their mode restored from 100644 to 100755; zero bytes of content changed.
• The lib/*.sh files are sourced rather than executed directly, so the permission drop had no runtime impact, but this restoration brings them back in line with the rest of the tree (backup.sh, verify.sh, setup.sh).

Confidence Score: 5/5

Pure mode restoration with no content changes — safe to merge immediately.

Every changed file shows only a 100644 → 100755 mode flip; git diff contains no content changes at all. The fix is narrowly scoped to restoring permissions that were unintentionally dropped by the temp-file rewrite pattern, and the five files selected match the description precisely.

No files require special attention.
