…tPy-Team#924)

Introduce RingClusterMotor, a Motor subclass that wraps a single
SolidMotor and models N identical motors arranged symmetrically on a
ring of given radius. Thrust, dry mass and propellant mass are scaled by
N, and the full inertia tensor is built via the parallel-axis theorem,
handling the dynamic propellant case and the asymmetric N=2
configuration via exact per-motor geometric summation.

Also extends the rocket draw layer to render clustered motors and adds
integration tests. RingClusterMotor is exported from rocketpy and
rocketpy.motors.

Feature developed by IPSA SPACE SYSTEMS.

- Bump pylintrc max-module-lines 3000->3050: environment.py now sits
  4 lines over the old hard limit purely from the logging import/setup
  this PR adds, tripping CI's fail-under=10 gate.
- Remove EmptyMotor import in rocket_plots.py, unused since PR RocketPy-Team#924
  switched that check to a string-based type-name comparison.
- Restore the exact pre-PR print() formatting (blank-line separators,
  dash dividers) in rocket_plots.py/environment_plots.py/flight_plots.py
  that got flattened when converting headers back to print() earlier
  in this branch.
- MonteCarlo: two logger.warning/error calls in __sim_producer run
  inside a multiprocessing worker process. Log handlers configured via
  enable_logging() in the parent process are not guaranteed to reach
  child processes (e.g. Windows "spawn"), so these would silently
  vanish -- exactly the cross-process issue already found and fixed
  for _SimMonitor in a prior commit on this branch, just missed here.
  Reverted to print()/_SimMonitor.reprint() for guaranteed visibility.
- For consistency with that worker output and with the still-visible
  per-iteration progress ticker, also reverted MonteCarlo's other
  lifecycle narration (start, worker count, results saved, file
  imports) to print(); logging module no longer needed in this file.

* MNT: address PR review comments on nose_cone and tools

* MNT: fix docstrings and scope debug log to verbose flag

* MNT: restore SimMonitor print behavior for multiprocessing compatibility

* MNT: keep print() for user-requested plot headers, document enable_logging

Plot section headers (e.g. 'Trajectory 3d Plot', 'Airfoil lift curve:')
are emitted by user-invoked .plots.xxx()/.all() calls, not internal
runtime events, so per this PR's own print-vs-logger distinction they
should remain print() -- otherwise they silently disappear by default
while the plot itself is still shown, and reading them in a log stream
disconnected from the plot window doesn't make sense. Diagnostic
logger.warning() calls for skipped/missing data are left untouched.

Also adds user-guide and API reference docs for enable_logging(),
closing the last unresolved review comment on the PR.

* MNT: revert FlightComparator output to print(), not logging

FlightComparator is an interactively-invoked reporting tool: add_data(),
compare(), summary() and all() exist specifically to print a
human-readable report the user is watching on their screen, exactly
like Flight.info()/Rocket.all_info() -- not an internal runtime event a
library embedder would want to filter or silence. Converting it to
logger.info()/logger.warning() meant summary() -- a method whose entire
purpose is printing a report -- produced no output at all under the
library's silent-by-default logging config, and the other methods lost
their multi-line human-readable formatting when consolidated into
single log records.

Restored the original print() calls and formatting verbatim, dropped
the now-unused logger import, and reverted the two tests that had been
migrated to caplog back to capsys to match.

Resolve conflicts in:
- rocketpy/simulation/flight.py: keep develop's logger.debug migration in the
  verbose block and re-apply the continuous-controller invocation alongside it.
- CHANGELOG.md: keep the RocketPy-Team#946 entry plus develop's RocketPy-Team#1043 and RocketPy-Team#924 entries.

* MNT: final fixes before next release

Documentation, CHANGELOG and test polish ahead of the next release
(v1.13.0), covering PRs merged since v1.12.0.

CHANGELOG
- Add missing entries: Individual Fins (#818), AIGFS/HRRR forecast
  models (#951), duplicate-controller fix (#949), Valkyrie flight
  example (#967).
- Hygiene: de-duplicate #958/#966, move #974 to Fixed and #1041 to
  Removed only, drop the already-released #914 duplicate, and point the
  logging (#973) and ND-interp (#969) entries at their PRs.
- Backfill #940/#941/#944 (shipped in v1.12.0 code but never logged)
  under the [v1.12.0] section.

Docs
- New exceptions reference page (rocketpy.exceptions) wired into the
  reference index; note UnstableRocketWarning in the rocket stability
  docs (#970).
- tanks.rst: switch examples to radius_function= and add a deprecation
  note (#957).
- forecast.rst: fix the HRRR example (missing code directive + stray
  sentence) (#951).
- airbrakes.rst: document discrete vs continuous controllers
  (sampling_rate=None) (#946).
- rocket_usage.rst: note that Parachute is now an abstract base;
  instantiate HemisphericalParachute (#958).

Tests
- New regression tests: 3D ND-interp NaN outside convex hull (#969),
  abstract Parachute cannot be instantiated (#958), Monte Carlo
  convergence stopping (#922), EnvironmentAnalysis surviving wind API
  (#1041), radial-burn grain geometry over time (#944), RingClusterMotor
  full flight (#924), discrete controller invoked once per node (#949),
  acceleration-based parachute trigger deploys (#911).
- Backfill regression tests for ThrustCurve API timeouts (#940) and
  power_off/on_drag Function objects + _input attributes (#941).
