Lataa TermCanvas 0.38.4

Changed
- Pin capture guidance is now issue-like: the injected agent instructions now tell agents to record high-density pins with Background, Observed / Request, Expected / Goal, Evidence / References, Next action, Why pinned, and Unknowns when the item is more than a lightweight memo. Thin context should be resolved by cheap local inspection or a concise user question before recording.
- Bottom toolbar no longer shows the canvas tool picker: removed the Move / Hand dropdown from the bottom toolbar while keeping keyboard-driven canvas navigation.
Fixed
- Literal \n leaked into pin detail views: pin bodies now normalize agent-style escaped line breaks at the store boundary while preserving single literal newline-escape mentions.
- Terminal cursor stayed as a grab hand in default hand mode: the canvas still defaults to Hand, but terminal tiles opt out of the inherited pan cursor and xterm text areas keep the text-selection cursor.
- Terminal tile window controls were hidden until hover: minimize and close controls now stay visible while hover-only state marks still use the existing reveal behavior.
