Consolidate duplicate functions, bump to v1.0.1

- Remove duplicate log/error_exit/warning/success/info from hops and
  uninstall; remove validate_password, generate_secure_password,
  create_docker_networks, validate_timezone from install. Single
  canonical copies now live in lib/common.sh, lib/security.sh,
  lib/validation.sh, and lib/docker.sh (A5, Q1)
- Fix lib/docker.sh, lib/validation.sh, lib/security.sh to use LIB_DIR
  instead of SCRIPT_DIR so sourcing them inside a function does not
  clobber the caller's SCRIPT_DIR
- Move SCRIPT_VERSION to lib/common.sh as the single source of truth;
  remove local declarations from hops, install, and uninstall
- uninstall now sources lib/common.sh directly for standalone safety
- validate_timezone updated to warn-and-default instead of error_exit
- validate_password updated to handle empty input (return 3)
- Update CHANGELOG and TODO to reflect resolved items (B1-B6, A1, A3,
  A5, Q1) and bump version to 1.0.1

+## [1.0.1] - 2026-06-10

+Stabilization pass: bug fixes, security hardening, and codebase consolidation
+on the Path A install pipeline.

+### Fixed
+- Infinite recursion in get_timezone_mount() and get_gpu_devices() on Linux (B1)
+- ((x++)) abort under set -e across hops and install (B5)
+- Glob stored as string breaking multi-user directory detection (B3)
+- Missing hops_service_definitions.sh reference in firewall setup (B4)
+- Linux-only guard missing from hops entry point (B6)
+- eval echo "~$SUDO_USER" replaced with getent passwd in uninstall (B3/S5)
 
 ### Changed
-- Version reset to 1.0.0
