Fuzz targets covering all input-processing functions:
- terminalstate: FuzzTrackerFeed, FuzzTrackerFeedIncremental
- normalize: FuzzNormalizeC1Controls, FuzzFilterDASequences
- slugify: FuzzSlugify (with unit tests)
- identity: FuzzGenerateID (with unit tests)
- replay: FuzzReplayBuffer, FuzzReplayBufferRapid
- svg_exporter: FuzzColorToHex, FuzzIsHex, FuzzRenderTerminalSVG
- shellsplit: FuzzShlexSplit (with unit test)
- twoway: FuzzTwoWayMap (with unit test)

All 14 targets validated with -fuzztime=3s, no panics found.
All unit tests pass with -race.
