fix(ios,macos): address PR #26 review findings

- ios/Runner.xcodeproj/project.pbxproj: Update RunnerTests TEST_HOST
  paths from Runner.app/Runner to Chanora.app/Chanora (target was
  renamed in prior commit but test config still pointed at old paths,
  breaking xcodebuild test).
- Cargo.toml: Move release DWARF flags from workspace [profile.release]
  into Apple-only podspec CARGO_PROFILE_RELEASE_* env vars so Android,
  Linux, Windows release builds stay lean (~10MB DWARF avoided).
- ios/Runner/Info.plist + macos/Runner/Info.plist: Flip
  ITSAppUsesNonExemptEncryption from false to true (Chanora ships
  ChaCha20-Poly1305 local storage + tsclientlib ECDH/AES-EAX voice
  channel encryption, not exempt under Apple export-compliance rules).
- scripts/verify_silero_exports.sh: Make slice-aware via lipo -archs
  loop + per-arch nm -arch invocation so universal macOS builds
  verify every architecture slice, not just whichever slice nm picks.
- .gitignore: Drop .omo/ and .playwright-mcp/ entries (scope leak;
  unrelated tooling state, not part of PR #26 archive-symbol concern).

-# Emit DWARF debug info in release builds.
+# Apple-only DWARF emission for archive validation lives in the iOS and
+# macOS chanora_bridge podspecs (apps/chanora_flutter/{ios,macos}/
+# chanora_bridge.podspec) as per-build environment overrides:
 #
-# Apple's archive validator (and App Store Connect upload) require a
-# matching `.dSYM` for every embedded framework, keyed by the framework
-# binary's LC_UUID. The CocoaPods bridge podspecs copy the cargo-built
-# `libchanora_bridge.dylib` into `chanora_bridge.framework/chanora_bridge`
-# and then run `dsymutil` on it (see apps/chanora_flutter/ios and
-# apps/chanora_flutter/macos podspecs). `dsymutil` needs DWARF in the
-# input binary to produce a useful dSYM with symbol records; without
-# `debug = true` here we'd ship a stripped binary and an empty/unusable
-# dSYM and TestFlight crash reports would be unsymbolicated.
+#   CARGO_PROFILE_RELEASE_DEBUG=true
+#   CARGO_PROFILE_RELEASE_SPLIT_DEBUGINFO=off
+#   CARGO_PROFILE_RELEASE_STRIP=false
 #
-# `split-debuginfo = "off"` keeps DWARF inside the dylib so install_name_tool
-# rewriting and the dsymutil pass both work without chasing per-object
-# `.o` files cargo would otherwise scatter under target/<triple>/release/deps.
-#
-# `strip = false` ensures cargo does not pre-strip the dylib before
-# dsymutil sees it. We strip the in-framework binary ourselves after the
-# dSYM is produced (handled in the podspec script phases).
-[profile.release]
-debug = true
-split-debuginfo = "off"
-strip = false
+# This keeps Android, Linux, and Windows release binaries on the cargo
+# default release profile (no DWARF, no extra ~10MB symbol payload).
+# Apple builds need the DWARF so dsymutil can emit a usable
+# chanora_bridge.framework.dSYM that the archive validator accepts.
