Develop Icod.DCurses 1.4.0 interaction routing

[uniblab]

Develops Icod.DCurses 1.4.0 interaction routing from the published v1.3.0 baseline.

Objective

Add deterministic, application-owned interaction routing over the existing semantic input, geometry, panel, and Terminal ownership foundations: bounded interaction regions, deterministic hit testing, logical focus/traversal/repair, semantic key gestures and command identities, panel-aware precedence, and curses-shaped pointer preferences/leases.

The release deliberately does not become a widget framework, hidden event loop, automatic layout owner, callback dispatcher, or raw terminal protocol layer.

Stable-source 1.4.0 then passed workflow #808 / 34774590867; the final release-facing documentation head 267f633e323f732ed041735210a86eda608a4697 passed workflow #810 / 34774819745 across all seven jobs.

T1405 adds the immutable CursesKeyGesture identity and terminal-independent matching semantics. T1406 adds CursesCommand, bounded local/global gesture registries, immutable CursesInteractionResult, and deterministic Text/Key/Paste/Mouse routing without application callbacks. T1407 adds the 30-value DCurses pointer-shape vocabulary, region/hit pointer preferences, and a DCurses lease wrapper which delegates reversible state ownership to Icod.Terminal without exposing Terminal pointer types publicly. T1408 proves resize/panel/lifecycle coherence. T1409 adds the public-DCurses-only interaction acceptance sample. T1410 freezes hot-path allocation/performance ceilings, maximum-capacity churn, deterministic replay, failure atomicity, and the no-callback/no-hidden-I/O boundary. T1411 completes the stable-API/package/docs/licensing regret review and refreshed dependency qualification without an API correction. T1412 promotes the accepted implementation/API through RC and stable-source identity and finishes exact-head release qualification.

During RC qualification, Windows ARM64 exposed a nondeterministic acceptance-test timeout: one rich-input test reused a single five-second cancellation token across seven sequential event reads. The unchanged RC job passed on rerun, confirming no production regression; the test was then hardened to use one bounded timeout per read. No production implementation or public API changed as part of that correction, and the hardened final RC and stable-source matrices are fully green.
