fix: resolve npm audit vulnerabilities in browser tools and whatsapp bridge (#8745)

* fix(telegram): use UTF-16 code units for message length splitting

Port from nearai/ironclaw#2304: Telegram's 4096 character limit is
measured in UTF-16 code units, not Unicode codepoints. Characters
outside the Basic Multilingual Plane (emoji like 😀, CJK Extension B,
musical symbols) are surrogate pairs: 1 Python char but 2 UTF-16 units.

Previously, truncate_message() used Python's len() which counts
codepoints. This could produce chunks exceeding Telegram's actual limit
when messages contain many astral-plane characters.

Changes:
- Add utf16_len() helper and _prefix_within_utf16_limit() for
  UTF-16-aware string measurement and truncation
- Add _custom_unit_to_cp() binary-search helper that maps a custom-unit
  budget to the largest safe codepoint slice position
- Update truncate_message() to accept optional len_fn parameter
- Telegram adapter now passes len_fn=utf16_len when splitting messages
- Fix fallback truncation in Telegram error handler to use
  _prefix_within_utf16_limit instead of codepoint slicing
- Update send_message_tool.py to use utf16_len for Telegram platform
- Add comprehensive tests: utf16_len, _prefix_within_utf16_limit,
  truncate_message with len_fn (emoji splitting, content preservation,
  code block handling)
- Update mock lambdas in reply_mode tests to accept **kw for len_fn

* fix: resolve npm audit vulnerabilities in browser tools and whatsapp bridge

Browser tools (agent-browser):
- Override lodash to 4.18.1 (fixes prototype pollution CVEs in transitive
  dep via node-simctl → @appium/logger). Not reachable in Hermes's code
  path but cleans the audit report.
- basic-ftp and brace-expansion updated via npm audit fix.

WhatsApp bridge:
- file-type updated (fixes infinite loop in ASF parser + ZIP bomb DoS)
- music-metadata updated (fixes infinite loop in ASF parser)
- path-to-regexp updated (fixes ReDoS, mitigated by localhost binding)

Both components now report 0 npm vulnerabilities.
