fix: add error logging to empty catch blocks in test helpers (#1334)

* fix: add error logging to empty catch blocks in test helpers

Previously, test helper functions had 14 empty catch blocks that
silently swallowed all errors during cleanup operations (reading and
deleting temporary stderr files).

This change adds error logging that:
- Allows expected errors (ENOENT for missing files, exit code 1 for cat)
- Logs unexpected errors to console for debugging

This improves test reliability by surfacing unexpected filesystem or
permission errors that could indicate real problems, while still
allowing the intended best-effort cleanup behavior.

Fixes: Empty catch blocks in 6 test files
Impact: Better test debugging and error visibility

* fix: improve error handling in Python fallback and directory deletion

1. Python arithmetic fallback (shared/common.sh:713):
   - Changed from: || echo "$((elapsed + 1))"
   - Changed to: explicit if/else with error detection
   - Impact: Python errors are now properly caught instead of masked by ||

2. Unvalidated directory deletion (cli/install.sh:142):
   - Added path validation before rm -rf
   - Checks: path is within dest directory AND directory exists
   - Impact: Prevents accidental deletion if variables are malformed

Both changes improve safety and error visibility without breaking
existing functionality.
