Add a muted flag to Keyframe. Muted keys stay in the Timeline and Graph Editor (dimmed, selectable and movable) but evaluation skips them, so the active neighbours interpolate as if they were not there; auto-Bezier and eases use the active neighbours. When every key is muted the property falls back to its static value.\n\nkeys.setMuted {muted} mutes or unmutes the selected keys in one undo step. The Timeline context menu offers Mute/Unmute Keyframes and the Animation menu has Mute Keyframes. Muted keys have no Bezier handles and motion-path points are dimmed.\n\nLottie export omits muted keys (with a warning) because Lottie has no mute state; scripting keeps seeing them in numKeys/key().\n\nTests: keyframe evaluation (linear, auto-Bezier spatial, all muted), serialization and value replacement, engine command + undo, Lottie export.
A few kilobytes of internal entities expanded to millions of nodes (each top-level
reference stays under roxmltree's per-reference cap), so a 1 MB file exhausted memory.
SVG keeps DTDs, which Illustrator's exports use for entities, but caps the expanded
document at 4 million nodes. Final Cut Pro XML and FCPXML, which FilmCraft parses
without a node limit, are refused when they declare an entity; real exports never do.

FCP 7 XML / FCPXML nested about 1 000 elements deep overflowed an 8 MiB stack in the XML
parser (aborting the app). Import now scans XML and OTIO JSON nesting first and returns
Error::TooDeep beyond 256 levels.

Removes the six expect() calls from timeline export/import and denies the panic lints in the
crate. A precomp layer whose source item is not a composition (a damaged project, or an item
that was deleted) made export panic in Exporter::sequence; it now leaves that layer out.
Exporter::sequence and track_item return Option, the Motion/Opacity/Volume effect defaults
come from effect_or_new (None if FilmCraft's registry lacks one), and import's motion() skips
a layer without a transform group.
