Cause: edit.copy handled text editing, selected keyframes, effects and shape
items, then fell back to copying the selected layers. Selecting a property
selects its keys, so an animated property copied, but an unanimated one (or
the Transform group, whose keys prop.select doesn't select) copied the whole
layer, and Paste added a duplicate layer instead of setting the property.
Fix: with properties (or the Transform group) selected, Edit > Copy copies, as
After Effects does, each animated property's keys (the selected ones, else all
of them, through keys.copy) and each unanimated property's value into a new
value clipboard keyed by match path. Edit > Paste sets those values on the
same properties of the selected layers (a key at the CTI where the target is
animated) and pastes the keys at the CTI, as one undo step (keys.paste now
honours `merge`). Keys alone still answer with their count, as before.
Test: copy_a_selected_property_pastes_onto_the_same_property (static
Position, then the Transform group with animated Opacity: values and keys
land on layer B, no layer is added, one undo step each).

(cherry picked from commit 8267519ebe20e889196e538de23b85b04a1fa76a)
- J / K (Go to Previous / Next Keyframe) and Ctrl+Alt+A (Select All Keyframes) act on what the
Timeline shows, as in After Effects: the keys of its revealed properties, layer and comp
markers and the work area (they used every property of the selected or all layers, revealed
or not). The commands take `visible: [{layer, prop}]`, which the Timeline fills in; agents
calling them without it keep the previous behaviour.
- Graph Editor ▸ Auto-Select Graph Type (an "Auto" button, on by default as in After Effects):
the speed graph when every property shown is spatial (Position, Anchor Point…), else the
value graph; choosing Value or Speed turns it off.
- Docs: parity, agents.

- Keys copied from several layers and pasted onto as many selected layers go first to first,
second to second, as in After Effects; every target used to receive every copied property
(the later ones overwriting the earlier).
- Edit ▸ Paste Reversed Keyframes mirrors the clipboard over its span and pastes it through
`keys.paste`, so it now follows the same rules as Paste: the layer's time stretch, the
selected target property, Hold-only properties, value conversion and roving keys (its own
simplified paste ignored them and kept existing keys' easing on a time collision).

- Double-clicking a keyframe of a numeric property (or its context menu ▸ Edit Value…) opens
the property's value dialog for that key, as in After Effects (it only moved the current
time); other keys still move the current time to them.
- The keyframe context menu has Select Equal Keyframes, Select Previous Keyframes and Select
Following Keyframes (`keys.selectEqual` / `selectPrevious` / `selectFollowing`).
- Roving keys draw as small dots in the Timeline, like After Effects.

- A drag (keys.move steps sharing a merge key) applies its total offset to the keys as they
were before it (`Session::key_move`, `prop::shift_keys`): dragging over another key of the
property no longer deletes it; only the drop position replaces a key, as in After Effects.
- Keys of time-stretched layers move with the pointer: offsets are applied in comp time and
snapped to comp frames (drags and Alt+Arrow nudges; they moved by the layer-time distance).
- Shift+click toggles a key in or out of the selection (`keys.select {toggle}`); Ctrl+click
switches Linear ↔ Auto Bezier and Ctrl+Alt+click toggles Hold.
- Keys of locked layers can't be selected (clicks, marquee, Select All Keyframes), so nothing
edits them.
- Toggle Hold off returns an eased key to Bezier (it always restored Linear).
- Shift-dragging a key snaps to everything the current time snaps to — other keys, layer in /
out points, layer and comp markers, the work area — and a tooltip shows the key's time and how
many frames it moved.

- Integrate main (render queue, timeline/keys, time remap, masks/pen, 3D, MCP/CLI).
- Menu tree now runs renderQueue.add, layer.enableTimeRemap, layer.timeReverse,
layer.freezeFrame/OnLastFrame, prop.separateDimensions, mask.setClosed,
layer.cameraSettings, view.3d.* / view.3d.last / view.reset3DView, main's
layer.autoOrient and keyframe velocity/interpolation/time-stretch dialogs;
matching stubs deleted (view.3d.default stays disabled).
- Keyframe clipboard is main's (keys.copy/paste); Paste Reversed Keyframes
reuses it. Animation-menu commands moved to commands/animation.rs.
- Main's spec menu paths/labels aligned with AE (Camera Settings under
Layer > Camera, "..." labels, Freeze On Last Frame).

Engine (all commands with undo/redo + tests in engine/src/tests_timeline.rs):
- keys.copy/paste (Edit Copy/Cut/Paste route to keys when keys are selected;
relative timing kept, paste at CTI, cross-property paste of same type),
keys.selectAll (Cmd+Alt+A), keys.nudge* (Alt+Arrow, Alt+Shift+Arrow),
keys.set / keys.setEase (graph editor drags), keys.info (dialog data),
keys.timeReverse; keys.interpolation gains continuous/auto Bezier, spatial
interpolation and roving; keys.velocity takes per-dimension values and
Continuous.
- Roving keys (keyframe::retime_roving): constant speed along the motion path.
- Layer > Time: layer.timeStretch (percent|duration, hold in/current/out),
layer.timeReverse (Cmd+Alt+R), layer.enableTimeRemap (Cmd+Alt+T),
layer.freezeFrame, layer.freezeOnLastFrame; render uses Time Remap as the
source time for precomp/footage layers.
- prop.separateDimensions (X/Y/Z Position; prop.set on Position writes them).
- layer.setParent compensates so the layer stays in place (compensate:false
to opt out).
- prop.pickWhip writes AE-style reference expressions (thisComp.layer(..),
effect(..)(..), mask(..).maskFeather, temp=…;[temp,temp], …[0]).
- prop.setExpression: syntax errors keep the text but disable the expression.
- expr: arrays of properties returned by an expression are resolved.
UI: Keyframe Velocity, Keyframe Interpolation and Time Stretch dialogs;
Graph Editor (value + speed graphs, draggable keys and Bezier/influence
handles, auto-zoom, fit, show selected, separate dimensions, hold/linear/
auto Bezier/Easy Ease buttons); key + layer context menus. Clears the
workspace clippy -D warnings failures.
