- Add explicit relative_to() containment check after path resolution so
CodeQL recognizes the plugin directory boundary (fixes 4 CodeQL alerts:
Uncontrolled data used in path expression, lines 168/172/189/205)
- Wrap requirements_file.read_bytes() in try/except OSError — on Raspberry
Pi with flaky SD card storage this can fail; returns False with a clear log
- Wrap marker_path.read_text() in try/except OSError — a corrupted marker
falls through to a clean reinstall instead of crashing
- Wrap both marker_path.write_text() calls in try/except OSError — pip
already succeeded at this point so a marker write failure should not
return False or propagate through the generic exception handler

The .dependencies_installed marker was an empty file, so adding a new
package to requirements.txt (e.g. astral in ledmatrix-weather v2.3.0)
never triggered a pip re-install on existing installs — the file existed
so the check returned early.
The marker now stores a SHA-256 hash of requirements.txt. On every plugin
load, the loader compares the current hash to the stored one; a mismatch
(or missing marker) triggers pip install and writes the new hash.
store_manager._install_dependencies() also writes the hash marker after a
store install/update so the loader skips a redundant pip run on next boot.
