fix: strip leading whitespace from sanitizeUserFacingText output (#16158)

* fix: strip leading whitespace from sanitizeUserFacingText output

LLM responses frequently begin with \n\n, which survives through
sanitizeUserFacingText and reaches the channel as visible blank lines.

Root cause: the function used trimmed text for empty-checks but returned
the untrimmed 'stripped' variable. Two one-line fixes:
1. Return empty string (not whitespace-only 'stripped') for blank input
2. Apply trimStart() to the final return value

Fixes the same issue as #8052 and #10612 but at the root cause
(sanitizeUserFacingText) rather than scattering trimStart across
multiple delivery paths.

* Changelog: note sanitizeUserFacingText whitespace normalization

- Security/Audit: warn when `gateway.tools.allow` re-enables default-denied tools over HTTP `POST /tools/invoke`, since this can increase RCE blast radius if the gateway is reachable.
- Security/Plugins/Hooks: harden npm-based installs by restricting specs to registry packages only, passing `--ignore-scripts` to `npm pack`, and cleaning up temp install directories.
- Feishu: stop persistent Typing reaction on NO_REPLY/suppressed runs by wiring reply-dispatcher cleanup to remove typing indicators. (#15464) Thanks @arosstale.
- Agents: strip leading whitespace/newlines from `sanitizeUserFacingText` output and normalize whitespace-only outputs to empty text. (#16158) Thanks @mcinteerj.
- BlueBubbles: gracefully degrade when Private API is disabled by filtering private-only actions, skipping private-only reactions/reply effects, and avoiding private reply markers so non-private flows remain usable. (#16002) Thanks @L-U-C-K-Y.
- Outbound: add a write-ahead delivery queue with crash-recovery retries to prevent lost outbound messages after gateway restarts. (#15636) Thanks @nabbilkhan, @thewilloftheshadow.
- Auto-reply/Threading: auto-inject implicit reply threading so `replyToMode` works without requiring model-emitted `[[reply_to_current]]`, while preserving `replyToMode: "off"` behavior for implicit Slack replies and keeping block-streaming chunk coalescing stable under `replyToMode: "first"`. (#14976) Thanks @Diaspar4u.
