## Summary
Follow-up to #4244's payload work: nukes were the last per-tick movers
flooding the worker → main update stream.
- **Core**: nuke trajectories are fully determined at launch
(precomputed parabola), so `NukeExecution` now records a `GridPathPlan`
when the nuke is built — same mechanism trade ships use — and the client
derives the position each tick. Per-tick `UnitUpdate`s for nukes in
flight are suppressed; only targetable flips and deletion
(interception/detonation) still emit. This covers atom bombs, hydrogen
bombs, and MIRV warheads (dozens of per-tick movers per MIRV
separation).
- The plan path replays a separate pathfinder rather than reusing the
stored trajectory array: the curve's cached points don't advance exactly
one index per tick, and the plan must match the movement pathfinder's
exact per-tick tile sequence.
- `startTick` accounts for MIRV warheads' staggered `waitTicks`.
- **Render**: `UnitPass.drawMissiles` now lerps each nuke's instance
position `lastPos→pos` by wall-clock progress through the current tick,
so nukes glide along their arc at render framerate instead of jumping
once per 100ms tick. Both endpoints are real simulated positions — the
rendered nuke trails the sim by at most one tick and settles exactly on
it when ticks stop. Plan-driven units sync `lastPos` on path-stall ticks
so the lerp never replays a segment. Shells keep their existing
two-instance trail; SAM missiles are unchanged.
## Test plan
- New `tests/nukes/NukeMotionPlan.test.ts`: tick-exact alignment between
the recorded plan and core nuke position over the whole flight
(mirroring `GameView.advanceMotionPlannedUnits` math), `waitTicks`
offset, and that no per-tick unit updates are emitted in flight except
targetable flips and deletion.
- Full suite passes (1452 + 65), tsc/eslint/prettier clean.
- Verified in-game (headless Chromium, real WebGL): atom bomb arcs from
silo to target with the client position driven by the plan, missile
sprite renders intact while the smoothing rewrites the instance buffer
every frame, detonation FX land at the target.

The blast-radius warning circle was always red, so players couldn't
tell who launched an incoming nuke. Now it's green for your own
nukes, yellow for ally/teammate nukes, and red for everyone else's.
Each telegraph carries a relation (0=self, 1=friendly, 2=enemy),
classified from the per-tick relation matrix — the same friend/foe
logic alt-view uses — and passed to the shader as a per-instance
attribute. Replay/spectator mode (no local player) stays all red.
Colors are tunable via the nukeTelegraph slice in render-settings.json.
When an alliance is within the renewal-prompt window, the alliance
icon above the player's name now pulses, ramping from 2 Hz to 5 Hz
as expiry approaches (same effect as the traitor flash).
The flash window is driven by allianceExtensionPromptOffset() — the
same Config value that triggers the "renew alliance" prompt in the
actionable events display — so the two always stay in sync.
The shader only knew the alliance fraction, not absolute time, so
computePlayerStatus now also emits allianceRemainingTicks, packed
into the free pd7.w slot of the player-data texture.
## Description:
Show nuke icons during replay too (when there's no localPlayer).
Show alliance request envelope icon, and duration in alliance icon
(weren't calculated yet).
Show ally and team mates' targets too (weren't calculated yet).
Remove unnecessary allocations. Nukes loop allocated two new sets,
transitive targets was a new set and now uses predicate with fallback to
localPlayer.targets, localPlayer.allies and localPlayer.embargoes were
both put in new set instead of using .includes directly.

and I've added it to the en.json file
- [x] I have added relevant tests to the test directory

The render/ tree was the only place in the client still using kebab-case
filenames. Brings ~80 files in line with the rest of src/client/
(BuildPreviewController, TransformHandler, etc.). Directories kept as
they were (name-pass/, fx-pass/, passes/, utils/, debug/) since the
codebase already mixes those.
Two collisions surfaced and got resolved: render/types/ is a directory,
not a file, so its imports kept the lowercase form; and the sed pass
incidentally normalized core/pathfinding imports, which had to be
reverted since that file is actually lowercase on disk despite some
imports having referenced it as ./Types under macOS case-insensitive
resolution.
The replay-path computePlayerStatus left alliance/target/embargo/
nukeTargetsMe at false, which meant the WebGL NamePass had no data
for those status icons after we switched names off canvas2D — they
just stopped appearing.
Add an opts param taking localPlayerID + tileState. When localPlayerID
is set, fill the relative flags by checking the local player's
allies/targets/embargoes against each other player's smallID;
embargo is bilateral (either side). nukeTargetsMe walks active nukes
and checks their targetTile's owner via the tileState buffer.
Plumb localPlayerID = myPlayer?.smallID() and tileState from
populateFrame so the live path uses the new mode. Emit an entry when
only a relative flag is true (previously could be dropped if no base
flag was set).
allianceReq and allianceFraction stay deferred (need local PlayerID
string for outgoing requests and current tick for fraction).
18 new tests covering both modes — replay (relative flags forced
false), and live (alliance one-way, target one-way, embargo bilateral,
self-flags suppressed, nukeTargetsMe with/without tileState,
relative-flag-alone emits, localPlayerID=0 falls back to replay,
allianceReq/allianceFraction stay deferred).
