When a Descend segment is followed by another Descend (or Traverse/
Diagonal) with a different heading, PathSegmentBuilder.Classify
correctly assigned ExitTransition=LandingRecovery, but BuildHints fell
into the `if (turning)` branch first and returned hints with
RequireStableFooting=true. That gate forces GroundedSegmentController to
wait for IsSettledOnTargetBlock (footprint inside, won't leave next tick,
horizontal speed^2 <= 0.0016), so a multi-block diagonal Descend that
landed inside the target block while still carrying ~0.02 m/tick of
residual jump momentum oscillated in place for ~60 ticks (3 seconds)
until the speed decayed.
Move the LandingRecovery branch ahead of the turning branch so the
Descend-carry handoff uses RequireStableFooting=false and the
ShouldComplete shortcut (LandingRecovery + footprint inside target on
the ground) fires the moment the bot reaches the landing column.
Adds two regression tests covering the Descend->turning-Descend handoff
and a sanity guard that ordinary Traverse->turning-Traverse still uses
the turning branch.
Also lifts DiagnosticsTailSize from 64 to 200 and emits an automatic
"slow segment" tick dump from PathSegmentManager whenever a segment
takes >=25 ticks, which is what surfaced this stall.

Fix a cluster of execution-layer issues that caused replans and void
falls when traversing narrow ledges and multi-block descents between
(251.5,141,210.5) and (252.5,138,220.5):
- WalkTemplate / GroundedSegmentController: suppress the pre-rotation
bias toward the next segment's exit heading on stable-footing Turn
exits where the next segment is not a jump. The next template
snaps yaw on its first tick anyway, and pre-rotating mid-stride on
a 1-block walkway pushes sprint drift perpendicular to the path and
walks the bot off the edge. Turn exits into a jump still get the
bias so the takeoff direction stays aligned.
- GroundedSegmentController.ShouldComplete: relax the headingReady
gate for Turn exits with stable footing so the segment can complete
once yaw is aligned with either the current or the next segment
heading (within 25/15 deg). Without this the removed bias would
leave the bot stuck at the end of a walkway waiting for a rotation
that never happens.
- DescendTemplate: restrict the airborne exit-heading bias so it only
kicks in when the footprint is inside the landing block, or on
single-step drops where the fall is too short for lateral drift to
miss the landing column. On 2+ block drops the bot now keeps yaw
pointed at the landing center for the whole fall.
- DescendTemplate: add a multi-block overshoot guard on PrepareJump
exits. Once airborne and past the landing end-plane on a 2+ Y
drop, release forward/sprint and press back briefly so air drag
pulls the bot back into the 1x1 landing column instead of sailing
one block past it into the neighbouring void.
Live round-trip between the two goal coordinates now completes with
zero replans in three consecutive runs in each direction. Full unit
test suite is unchanged from the pre-existing baseline (22 failing
tests, all orthogonal to this change).

Move PathSegmentManager's Replan to Task.Run so the main tick only reads
results and swaps executors, and introduce a _nextExecutor pre-planning
slot so upcoming segments can prepare while the current one finishes.
Relax per-tick yaw/pitch rate limiting: allow instantaneous snapping
before jump ticks (Baritone does this and servers do not kick for it).
Align jump-template success/failure contracts with Baritone:
- Success key shifts from "speed squared" to "feet-on-target block".
- Failure window widened to the ~200 tick range.
- AscendTemplate gets a headBonkClear + edge/side proximity
precondition so launches only happen from a safe takeoff.
Expose an initialMomentumTicks option on TemplateSimulationRunner so
follow-up sidewall scenarios can warm up physics before a template
starts.

Phase 2.2: MoveParkour for sprint-jump across 1-2 block gaps (distance 2-3)
and ascending parkour (distance 2, +1Y). Registered in BuildDefaultMoves
with CalculationContext.AllowParkour gating.
Phase 3.1-3.2: Template execution engine replacing the waypoint queue system.
- IActionTemplate interface with per-tick state machine pattern
- Templates: Walk, Ascend, Descend, Climb, Fall, SprintJump
- ActionTemplateFactory maps MoveType to the correct template
- PathExecutor drives sequential template execution with logging
- PathSegmentManager handles replanning on failure (up to 5 retries)
- McClient integration: MoveToAStar now creates PathSegmentManager,
UpdatePathfindingInput delegates to it, CancelMovement/ClientIsMoving
updated for both old and new systems.
Tested on 1.21.11: straight walk, zigzag maze, stair ascent,
1-gap and 2-gap sprint jumps all pass.
