Click and hold nukes

[Pesinario]

Add approved & assigned issue number here:
Resolves #5315

Description:

Current implementation:

• Adding click+hold functionality to launch multiple nukes via ConfirmGhostStructureEvent Instead of the prototype's mouse event approach.
• Behavior is restricted to mouse (via event.pointerType === "mouse") for the time being.

Potential additions/changes considered (Feedback desired):

Worth mentioning: This different PR (which also stems from the prototype, see Issue#5265) deals with a different approach to empowering the player.

Resulting behavior is that the interval would fire as many nukes as uiState.upgradeMultiplier has active. This might be relevant because in practice, the combination of both is often overkill. This will get addressed when/if either PR gets merged.

Note: PR is set to draft initially so that discussion about these changes can happen before committing to a final approach.

• Add a setting (defaults to true) under "Gameplay" to disable the behavior:

  • Pro: Give more power to the user to customize their experience.
  • Con: Settings bloated by one additional toggle.

• Add additional settings to control the HOLD_POINTER_WAIT_MS and HOLD_SECOND_ACTION_DELAY_MS variables:

  • Pro: Give more power to the user to customize their experience.
  • Con: Settings bloated by two additional sliders.

• Different approaches to input method (In comparison to current one):

  • Changing behavior to a key (such as Enter, which already confirms ghost events) instead of holding click:
    • Pro: Would make accidental triggering of the rapid-fire mechanic less common.
    • Con: A key only solution would be less intuitive than holding click.
  • Adding a key to trigger behavior:
    • Pro: Give more power to the user to customize their experience.
    • Con: It should be rebindable, and therefore would also bloat settings.
  • Requiring a key to be held down for the behavior to trigger.
    • Pro: Pretty much ensures no accidental triggering ever.
    • Con: Severely harms usefulness, as it would be cumbersome.

• Expanding behavior to structures that are not nukes

  • Con: Slightly outside the scope of this PR (I don't mind, but the reviewer might).
  • As expanding the existing AutoUpgradeEvent pipeline:
    • Pro: Would split behavior between offensive actions, could set a different (probably slower) interval.
  • As left click holding:
    • Pro: Would be potentially useful for upgrading structures.

Walkthrough

InputHandler now supports mouse click-and-hold actions for Atom Bomb and Hydrogen Bomb ghost structures. Holds confirm after a grace period and repeat at a fixed rate. Movement, release, blur, and destruction clean up the hold state. Tests cover timing and cancellation cases.

Changes

Ghost structure click-hold

Layer / File(s)	Summary
Hold confirmation and repeat behavior src/client/InputHandler.ts, tests/InputHandler.test.ts	Mouse pointer-down events start hold processing for valid bomb ghosts. The handler emits the initial confirmation, delays the second action, and emits repeated confirmations. Tests cover stationary and post-drag holds.
Hold cancellation and cleanup src/client/InputHandler.ts, tests/InputHandler.test.ts	Pointer movement before the grace period cancels the hold. Pointer release suppresses duplicate taps when required. Blur and destruction clear hold timers and intervals. Tests cover release and cancellation behavior.

Priority: ⬇️ Low

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: 🟡 Moderate · up to 39bc8

Releasing a completed mouse hold can launch an unintended extra bomb. This should be corrected before merge.

Inline comments:
In `@src/client/InputHandler.ts`:
- Around line 853-854: Update the mouse-release handling in InputHandler so it
consumes and clears suppressNextTap when a held valid ghost has already emitted
ConfirmGhostStructureEvent, preventing MouseUpEvent from launching another
action. Keep the existing touch behavior intact and ensure the flag cannot
remain set to suppress a later touch tap.

In `@tests/InputHandler.test.ts`:
- Around line 1002-1024: Replace the mocked GameView/InputHandler setup in the
affected tests with the shared setup() helper from Setup.ts, supplying map data
as needed. Exercise pointer interactions through the initialized game instance
and registered event path, including mouse release and confirmation handling,
rather than invoking private handlers or relying on mock objects.
- Line 1268: Update the timer advancement in the test around
clickHoldEnsureIntent to advance beyond HOLD_SECOND_ACTION_DELAY_MS, or flush
all pending timers, before asserting the delayed action was cleared.
