Cld 1267/global hook reg

[bytesizedroll]

Summary

• Adds AddGlobalPreHooks(...PreHook) and AddGlobalPostHooks(...PostHook) methods to ChangesetsRegistry
• Global hooks run on every changeset in the registry (wired into Apply() in Story 4)
• Thread-safe via the existing sync.Mutex pattern
• Multiple calls are additive; no global hooks = identical behavior to today

Test plan

• Package compiles cleanly
• 0 lint issues (golangci-lint)
• All existing changeset tests pass unchanged

Please add tests for these

[bytesizedroll]

@jkongie I have these three Jiras to completely test all teh new code:

https://smartcontract-it.atlassian.net/browse/CLD-1269
https://smartcontract-it.atlassian.net/browse/CLD-1270
https://smartcontract-it.atlassian.net/browse/CLD-1271

Am trying to keep the implementation PRs focused and the test PRs thorough rather than adding minimal tests as an afterthought on each story.
