chore(deps): bump phasetida_flutter to 0.2.0

[nofyso]

phasetida has updated, here are update notes:

• refactored the project, chart rendering is no longer using web page now

Changes in summary:

old:
wasm-core -> vite frontend -> local server -> webview

now (maybe a bit more faster than before):
core -> core shell in phasetida_flutter -> dart ffi -> render in flutter canvas

• added hit sound of notes
• fixed wrong creations of splash effects of hold notes when adjusting the time
• removed useless non-auto play mode
