ambientops: port emergency-room to Zig; move V sources to donation
Ports emergency-room/src/ (11 .v files ~2762 LOC) to src/zig/ per V-lang ban (2026-04-10). zig build exit 0. Panic-safe intake, offline-first, non-destructive semantics preserved via error unions and defer/errdefer — no @Panic as error handling. V sources moved to developer-ecosystem/v-ecosystem/v-api-interfaces/ v-ambientops-emergency-room/ for donation to the V community per the V→v-ecosystem move policy (see feedback_v_sources_move_not_delete). - emergency-room/src/zig/{main,utils,incident,capture,handoff,backup, boot_guardian,shutdown_marshal}.zig + _test.zig files - emergency-room/build.zig - emergency-room/MIGRATION.adoc (V→Zig mapping table) - emergency-room/src/*.v deleted (moved to v-ecosystem donation) - emergency-room/v.mod deleted (moved alongside) Recovery/emergency-room symlink wrapper untouched; its .v symlinks point at emergency-button/src/ (a different canonical source) and remain valid until that .v tree also leaves.

= Emergency Room — V-lang Deprecated (2026-04-12); Zig Port Complete (2026-04-17)

== Status
77

88
The V-lang implementation in `src/` is *deprecated* as of 2026-04-12
99
following the estate-wide V-lang ban (2026-04-10).

== Migration Target: Rust
11+
A Zig port is *complete* as of 2026-04-17 at `src/zig/`.
12+
The binary name is `emergency-button` (unchanged).
13+
Both the Rust crate and the Zig port are maintained until one is designated canonical.
14+
15+
== Migration Target: Zig (Preferred — 2026-04-17)
16+
17+
The Zig port is at `src/zig/` in this directory, built via `build.zig` at the repo root.
