fix: add browser_console to browser toolset and core tools list (#1084)

browser_console was registered in the tool registry but missing from
all toolset definitions (TOOLSETS, _HERMES_CORE_TOOLS, _LEGACY_TOOLSET_MAP),
so the agent could never discover or use it.

Added to all 4 locations + 4 wiring tests.

Cherry-picked from PR #1084 by @0xbyt4 (authorship preserved in tests).
