Brennan Benson e04ca97dc2 fix(mobile): re-fit terminal PTY when the frame height settles (#8647)
* fix(mobile): re-fit terminal PTY when the frame height settles

A freshly-created agent terminal fits its PTY to rows = floor(frameHeight
/ cellHeight) before the accessory/live-input dock has laid out, so the
frame is briefly too tall and the PTY gets too many rows. Claude/Codex
pin their input box to the bottom of the grid, so those extra bottom rows
— the input box and status lines — render behind the dock and you can't
see what you're typing. Leaving and re-entering the workspace worked
around it by re-measuring against the settled layout.

The refit hook previously re-fit only on width changes and deliberately
ignored height-only changes, so the over-fit was never corrected. Track
the measured frame height and re-fit on its change too, mirroring the
width path. Safe because Expo SDK 55's edge-to-edge IME overlays instead
of resizing, so the frame height doesn't change on keyboard toggle and
the PTY is never reflowed while typing; the refit's row-count guard makes
sub-row jitter a no-op.

* fix(mobile): guard height refit against IME resize; test the decision

Address review on #8647:
- Extract shouldRefitOnFrameHeightChange (pure) and gate the height refit on
  keyboard-visible, so an IME that resizes the window (Android adjustResize)
  can never reflow the PTY while typing — no longer relies on the edge-to-edge
  no-resize assumption alone.
- Add a behavioral test for the decision helper (height transition, same-value
  no-op, keyboard-open skip) instead of only source-string assertions.
- Trim the added comments to 1-2 lines per AGENTS.md.
