Subject: [PATCH] build: add release build tasks with linker flags (#239)

* fix(container): prevent data race in State.Get and State.All

Return copies of Container structs instead of pointers to the map
entries. This prevents data races when containers are modified
concurrently by waitForExit and Stop.

Fixes #76

* fix(updater): resolve PkgVersion duplicate declaration

Remove var PkgVersion from updater.go since go generate creates
const PkgVersion in version.go. Track version.go in git to ensure
builds work without running go generate first.

* build: add release build tasks with linker flags for smaller binary

Add -s -w linker flags to strip debug info and symbol table:
- cli:build:release - release build to ./bin/core
- cli:install:release - release install to system PATH

Binary size reduced from 19MB to 14MB (26% reduction).

Fixes #226
