feat: Add registry for reservation rule classes

[tvk134]

Summary:

• Refactor reservation-generated resource-management rules into individual Rule subclasses.
• Add a ReservationRuleRegistry that maps reservation rule names to Rule constructors.
• Add a DefaultReservationRuleGenerator that uses the registry to construct rules for a reservation.
• Update ResourceManager.generate_load_rules to delegate rule construction while preserving rule scheduling, expiration, and memory-reset behavior.
• Expose ResourceManager.get_reservation_rule_registry() so users can disable or replace individual reservation rules without subclassing the generator.

Testing:

• uv run ruff check sequence/resource_management/resource_manager.py sequence/resource_management/reservation_rule_registry.py tests/resource_management/test_reservation_rule_registry.py
• uv run pytest tests/resource_management -vv
• uv run pytest tests/network_management -vv
• uv run pytest tests/topology -vv
• uv run pytest tests/app -vv
• uv run pytest tests/components -vv
• uv run pytest tests/entanglement_management -vv
• uv run pytest tests/kernel -vv
• uv run pytest tests/qkd -vv
• uv run pytest tests/qlan -vv
• uv run pytest tests/utils -vv

Note:

• Full uv run pytest -vv hangs locally during collection on Windows at 228 collected items, including after a restart and several minutes of waiting.
• Running each top-level test directory individually completes successfully.

Pushed the discussed updates.

Summary:

• Renamed DefaultReservationRuleGenerator to ReservationRuleGenerator.
• Removed the custom registry injection path; the generator now owns its registry initialized with the default reservation rule constructors.
• Kept ResourceManager.get_reservation_rule_registry() as the configuration hook for replacing/disabling individual reservation-generated rules.
• Made reservation rule priority an init parameter with the existing default value of 10.
• Added a generator-level test verifying that a registered replacement rule is actually produced by create_rules(...), not just stored in the registry.
• Cleaned up the reservation rule registry tests.

Validation:

• uv run pytest tests/resource_management/test_reservation_rule_registry.py
  • All 4 passed
• uv run pytest tests/resource_management
  • All 16 passed
