release: v0.0.71 — MCP tool surface diet - #54

Also fixes negotiation.test.ts expectations, which hardcoded the old full-by-default browser tool counts and now regress under the core default.
Fold highlightElement/highlightText into browser_highlight and
readStorage/writeStorage into browser_storage, each resolving to the
right builtin via a new GeneratedTool.resolve hook that runs before
capability validation so tiers and dangerous accounting see the real
builtin. Drop navigateBack/navigateForward from the MCP surface in
favour of navigate({action}). Full mode now advertises 51 browser
tools (58 TOOL_DEFS - 3 blocked - 6 merged-away + 2 merged).
handleBrowserTool resolves before validateCall/hub.exec; BROWSER_BY_NAME
now indexes the full tool table so a merged or dropped tool can still be
looked up regardless of the advertised mode; buildToolList filters by
builtinTools.every(...) so a merged tool is only advertised when the
worker supports every underlying builtin.
browser_discoverTools could advertise and enable tools the connected worker cannot execute, since it only checked whether a name existed in the catalog. handleDiscover now takes an optional `supported` builtin set: catalog only lists runnable tools, and enable requests for a tool that exists but the worker can't run land in a new `unsupported` field instead of being silently advertised. dispatchCall wires this from the existing workerToolSupport(deps) (peek-only, never binds a port).
- README: name the legacy-extension fallback set instead of a bare "19" that collided with the "其余 19 个" line above, and state the actual consequence under the new default (9-tool intersection with core, browser_storage never listed since old extensions lack writeStorage). - SKILL.md: the 填表+提交 scenario now calls out that submitForm needs browser_discoverTools first, like the 翻页采集 scenario already does; replaced askUser/detachTab/attachTab flow instructions (not exposed over MCP) with in-reply confirmation and dropped the detach step. - tests/tool-gen.test.ts: renamed the "55 - 5 + 2" title, which no longer matched TOOL_DEFS' actual count, to spell out the real arithmetic (58 - 3 blocked - 6 merged-away + 2 merged).
