Fixes #11249

Overrides Input._watch_value in a _PromptTextInput subclass to skip self.virtual_size = Size(...) — a Reactive(layout=True) that kept Textual's WriterThread queue non-empty during typing, preventing stdout from flushing and characters from appearing on screen.

Closes #11249

Fixes #11249 Overrides `Input._watch_value` in a `_PromptTextInput` subclass to skip `self.virtual_size = Size(...)` — a `Reactive(layout=True)` that kept Textual's `WriterThread` queue non-empty during typing, preventing stdout from flushing and characters from appearing on screen. Closes #11249

Input._watch_value sets self.virtual_size (Reactive layout=True) on every
keystroke, keeping Textual's WriterThread write queue permanently non-empty.
The queue never reaches qsize()==0 so flush() is never called and typed
characters are invisible until Enter drains the queue via conversation.update().

_PromptTextInput subclasses Input and overrides _watch_value to skip the
virtual_size update while preserving Changed event, _suggestion reset and
initial cursor positioning. The prompt is single-line and never scrolls
horizontally so omitting virtual_size is safe.

Input._watch_value sets self.virtual_size (Reactive layout=True) on every
keystroke, keeping Textual's WriterThread write queue permanently non-empty.
The queue never reaches qsize()==0 so flush() is never called and typed
characters are invisible until Enter drains the queue.

Two fixes applied:

1. _PromptTextInput subclasses textual.widgets.Input and overrides
   virtual_size with Reactive(layout=False). Setting virtual_size in
   _watch_value no longer triggers refresh(layout=True). Zero type:ignore
   suppressions — uses proper Textual reactive types.

2. CSS #prompt and #prompt > Input changed from height:auto to fixed
   heights (3 and 1). This prevents the auto_dimensions guard in
   _watch_value from adding a second refresh(layout=True) per keystroke.

3 BDD regression scenarios added covering: virtual_size layout=False,
_PromptInputBase usage in _TextualPromptInput, and fixed CSS height.

The typecheck session was installing only the base package (-e .)
without the tui optional dependency, so pyright could not resolve
the textual.geometry, textual.reactive, and textual.widgets imports
that prompt.py conditionally loads when _TEXTUAL_AVAILABLE is True.

Changing to -e .[tui] ensures textual is present in the typecheck
venv so pyright reports no reportMissingImports errors.

Pyright evaluates `if _TEXTUAL_AVAILABLE:` blocks statically and raises
reportMissingImports for textual.geometry, textual.reactive, and
textual.widgets. Add `# type: ignore[import]` to the three conditional
imports so typecheck passes when textual is not installed in the
check environment.

📋 Estimate: tier 1.

Single-file security fix (+7/-1) replacing startswith() path matching with os.path.relpath-based containment. The change itself is small and focused, but tier 1 is warranted because: (1) security fixes require cross-file context to confirm the fix is complete and correctly applied at all relevant call sites; (2) CI is failing on unit_tests (errored scenarios in actor_run_signature, plan_service_coverage, tdd_memory_service_entity_persistence — all unrelated to path containment) and integration_tests (job ran 1h26m of testing but was cut at 3m15s elapsed — consistent with the known CI runner reaper pattern); the implementer needs to assess whether these failures are pre-existing/infrastructure noise or introduced by the PR. Tier 0 was considered but rejected given the security context and the need to triage CI failures.

📋 Estimate: tier 1.

Core change is focused: subclass Textual's Input widget in tui/widgets/prompt.py to override _watch_value and skip the layout=True reactive. Typecheck failure is directly caused by the PR — textual imports (textual.geometry, textual.reactive, textual.widgets) are unresolvable in the CI pyright environment, requiring a dependency/pyproject.toml fix alongside the widget subclassing. Unit and integration test failures (actor_run_signature, plan_service_coverage, tdd_memory_service_entity_persistence) are entirely unrelated to TUI changes and are likely pre-existing or CI flakes. The fix itself is multi-file (+193/-3 across 4 files) with cross-cutting concerns between the widget implementation and the dependency configuration — standard tier-1 engineering work.
