Goober5000andClaude Opus 5 e2be023f84 Replace the Cockpit_active global with computed predicates
Cockpit_active was latched inside ship_render_player_ship(), which only
runs when Viewer_obj is non-null.  External, chase, warp-chase, topdown,
free-camera and dead views all null Viewer_obj, so the flag froze at its
last cockpit-view value and cockpitinactive HUD gauges vanished.  It was
also read before being written each frame (by the show-ship check and the
shadow helpers), so those decisions lagged a frame on any transition.

Replace it with three functions computed on demand:
- ship_cockpit_enabled(sip): the ship has a cockpit model and cockpits
  aren't disabled; used by the Show_ship_only_if_cockpits_enabled checks
- ship_render_player_cockpit(sip): the above, outside topdown view;
  replaces three duplicated copies of that expression
- ship_render_player_cockpit_active(): whether the viewer's cockpit is
  being rendered this frame; used by the HUD cockpit-view-choice checks

With the predicate correct, the VM_CHASE special cases added for #4804
are no longer needed and are removed.  In chase view, cockpitinactive
gauges now also respect pop-up state, No_ets, and setRenderOverride,
which the early return in HudGauge::canRender() used to bypass.

Goober5000andClaude Fable 5 7b241812ed make ship move-correct
Ship's implicit move operations compiled but were semantically broken in
two ways: moving copied the subsys_list sentinel's links verbatim,
leaving the bookend nodes of the intrusive subsystem list pointing at
the old sentinel address; and the raw owning warpin_effect /
warpout_effect pointers were copied without nulling the source, so a
vacated Ships[] slot aliased live WarpEffects that ship::clear() (on
slot reuse) or ship_close() (which walks every slot) would delete out
from under the destination ship.

Fix both at the member level so the compiler-generated moves are
correct by composition:

- Add ship_subsys_sentinel, derived from ship_subsys, whose move
  operations re-link the bookend nodes (handling the null-linked,
  self-referential-empty, and populated source states) and leave the
  moved-from sentinel as an initialized empty list.  Copying is
  deleted.  Public inheritance keeps &ship::subsys_list convertible to
  ship_subsys*, so list_init, GET_FIRST, and every other call site is
  unchanged.

- Convert warpin_effect and warpout_effect to std::unique_ptr.  The
  delete-and-null blocks in ship::clear(), ship_close(), and
  ship_set_warp_effects() collapse into reset(); call sites that borrow
  the pointer into a raw local now use get().

With the members handling themselves, declare ship's special member
functions: defaulted default constructor and moves, deleted copies
(previously implicit via the unique_ptr members, now stated intent).
The moves are deliberately not declared noexcept because members like
SCP_map and std::deque do not have standard-guaranteed nothrow moves;
the computed exception specification is used instead.

Goober5000andClaude Opus 4.8 bed228d264 avoid undefined behavior from UNREACHABLE on reachable code paths (#7555)
* avoid undefined behavior from UNREACHABLE on reachable code paths

UNREACHABLE expands to __assume(false) / __builtin_unreachable() in
release builds, which is undefined behavior if the code is ever actually
reached. Many UNREACHABLE sites only guard against unexpected-but-
possible runtime states (values from tables, mission/save files, network
packets, scripting, or user input), so reaching them should degrade
gracefully rather than invoke UB.

Replace UNREACHABLE with Assertion(false, ...) at all such sites. It
still pops an error in debug builds, but in release it is a harmless
no-op that simply falls through to the following code. Sites that are
genuinely unreachable by local invariants (e.g. a switch over a bounded
random number) are left as UNREACHABLE.

A few converted sites had no safe fall-through -- an uninitialized read,
null dereference, or null call would have followed -- so they also get a
minimal recovery: initialize the value, guard the dereference, return
early, or skip the offending item.

Where the converted site was a simple guard of the form
    if (x) { Assertion(false, ...); return; }
hoist the check onto the invariant instead:
    Assertion(!x, ...);
    if (x) { return; }
This states the expectation directly and shows the offending value in
the debug popup, while keeping the same graceful runtime degradation.

* addendum

After consultation with Lafiel, use UNREACHABLE in situations that are effectively impossible even if not provably impossible.  UNREACHABLE = "this shouldn't ever happen"; Assertion = "if this ever happens, it's a coding error".  Also fix a few other sites and change a couple to Warnings.

wookieejedi 7eff7900a6 Allow mods to tune generic debris generation (#7027)
* Allow 'No Impact Debris' to also apply to explosions

The ship/subsystem flag `no impact debris` prevents the default debris shards from spawning, which is very valuable especially now that impact effects can be completely customized via the -particles table. Now that particle effects are also an option for ship and subsystems explosions, it is also invaluable to have the ability to turn off the spawning of shards when either of those explosions happen.

This PR uses the same flag of `no impact debris` and simply does not spawn the default shards for ship explosions or subsystem explosions of that flag is enabled. I thought about adding two new flags, but that would add to the flag clutter, and most folks who use these flags to turn off impacts I would estimate also want them off for actual explosions. Also, a new flag called `no explosion debris` would likely be confusing, so if a new flag were to be added it should be called something like `no default explosion debris shards` or something. Overall I've opted with the simpler and cleaner solution to just have it all under the impact flags. If two new flags are desired though I can easily add them.

Tested and works as expected.

wookieejedi 2576515040 Allow Trigger Radius curve input to work with muzzle effects (#6706)
The Input of `Trigger Radius` for curves within new particle effects was never hooked up for muzzle flashes, so this PR adds in the necessary lines to get it working. This allows modders to make a muzzle effect that can scale to the weapon radius through curves, and thus modders can simply make one curve scaled muzzle flash and avoid making a many muzzle flashes for each sized weapon that uses the same base effect.

Tested and works as expected.

Goober5000 d31f0a1b79 several fixes to ship sparks
1. Refactor `num_hits` to `num_sparks` and `MAX_SHIP_HITS` to `MAX_SHIP_SPARKS` to be consistent with their current (since FS1 pre-release) usage.
2. Remove the unused `HP_SCALE`.
3. Always initialize at least one spark pair.  If `choose_next_spark()` was entered when `num_sparks` was 1, `num_spark_pairs` would be 0 and none of the spark pairs would be initialized.  Consequently, accessing the pair at index 0 would return garbage data.
4. Iterate through `num_spark_pairs` when counting the indexes, rather than the hardcoded (and incorrect) magic number 6.

Fixes a crash discovered by Dawnesya that can only occur when a ship has both the "fighter" and "cruiser" flags.  Normally, fighters never enter the `choose_next_spark()` function and 'big' ships always have at least 3 sparks.

wookieejedi 7a07c995ca Add Mod Option to Limit 'Show Ship' when Toggling Cockpits (#6513)
* Add Mod Option to Limit 'Show Ship' when Toggling Cockpits

FotG uses cockpits and 'show ship', and also provides a way for players to toggle off cockpits. Unfortunately, if the player disables cockpits, 'show ship' still appears and looks very odd (since it appears the player is flying a ship with a hole in the center where the cockpit would be). Other mods have made entire ships with their cockpits, but FotG needs to use 'show ship' to match team colors and moving external ship animations.

This PR adds a game_settings option that allows mods to set to only use 'show ship' if cockpits are enabled.

Tested and works as expected.

Goober5000 dfbf4da3fb fix engine wash
An idiosyncrasy of the original implementation of `timestamp_until()` is that "immediate" timestamps that expired would be negative.  Only one remaining spot in the codebase relied on this: engine wash.  When #6258 fixed `timestamp_until()` to return 0 for immediate timestamps, engine wash broke.  Changing the comparison from `<` to `<=` fixes it.  I searched the code and there are no similar uses of `timestamp_until()` or `timestamp_since()`.

In the process of searching, though, I found two uses of `timestamp_since()` that were converted from `timestamp_until()` in PR #4286.  These particular conversions more properly include the 0 rather than exclude it, so I changed these as well.
