[AUTOMATON] Make rusty-bubbletea Windows-safe for release dependency validation

[coderbants]

mutate-work-id:AUTOMATON-WIN-BUBBLETEA

Bonobo PR #39 cannot reach its native Windows gate because the current rusty-bubbletea terminal and TTY implementation imports Unix-only descriptor and libc APIs. Implement the portability remediation in rusty-bubbletea, keep Unix behavior intact, add deterministic Windows regression coverage, and document any intentionally unsupported native terminal operations. Do not modify Bonobo or Panache from this owner ticket.

Acceptance criteria

• AC-AUTOMATON-WIN-BUBBLETEA-A: Make the owning rusty-bubbletea terminal and TTY implementation compile on Windows without Unix-only descriptor imports or libc calls.
• AC-AUTOMATON-WIN-BUBBLETEA-B: Add deterministic Windows regression coverage for unsupported terminal operations and preserve Unix terminal behavior and exact public API contracts.
• AC-AUTOMATON-WIN-BUBBLETEA-C: Document the Windows compile-safe behavior and intentionally deferred native functionality in the owning repository mapping.
• AC-AUTOMATON-WIN-BUBBLETEA-D: An independent reviewer confirms the owner-only portability change, public surface, tests, documentation, and dependency scope at the exact protected head.

Acceptance criteria

Criterion	Status	Definition of done	Evidence
AC-AUTOMATON-WIN-BUBBLETEA-A	met	Make the owning rusty-bubbletea terminal and TTY implementation compile on Windows without Unix-only descriptor imports or libc calls.	The terminal and optimized-movement Unix dependencies are cfg-gated and Windows exposes deterministic compile-safe lifecycle fallbacks.
AC-AUTOMATON-WIN-BUBBLETEA-B	met	Add deterministic Windows regression coverage for unsupported terminal operations and preserve Unix terminal behavior and exact public API contracts.	Windows tests verify raw-mode and terminal lifecycle fallbacks while the Unix implementation remains unchanged behind Unix cfg boundaries.
AC-AUTOMATON-WIN-BUBBLETEA-C	met	Document the Windows compile-safe behavior and intentionally deferred native functionality in the owning repository mapping.	UPSTREAM_MAPPING.md records the Windows terminal boundary, deferred native adapter behavior, and exact regression targets.
AC-AUTOMATON-WIN-BUBBLETEA-D	pending	An independent reviewer confirms the owner-only portability change, public surface, tests, documentation, and dependency scope at the exact protected head.	—
