docs(adr): write ADR-165 (HOMECORE-MIGRATE), repoint migrate 134→165 — ADR-164 G3

homecore-migrate cited "ADR-134 (HOMECORE-MIGRATE)", but on-disk ADR-134 is
"First-Class CIR Support" — a different decision. The migrate crate was governed
by a phantom identity (ADR-164 Gap G3).

- New ADR-165-homecore-migrate-from-home-assistant.md (next free number),
  reverse-documented from the shipped P1 scaffold: HA .storage reader, versioned
  format gate (unknown minor_version = hard error), per-artifact parsers, inspect
  CLI, structured errors. Status: Accepted — P1 scaffold (full conversion P2).
  Trust-boundary rationale for the untrusted .storage import is the centerpiece.
- Repointed every ADR-134 governing reference in v2/crates/homecore-migrate/
  (Cargo.toml, README.md, src/lib.rs, src/config_entries.rs,
  src/storage_format/mod.rs) → ADR-165. Left the ADR-132 (recorder-feature)
  refs intact. Explanatory renumber notes retained.
- On-disk ADR-134 (CIR) untouched. ADR-126 series-map registry row owner-gated.

Docs/comments only — cargo build -p homecore-migrate --no-default-features
still compiles.
