Unblock the monorepo sync check: prompt registration and the browser-evidence skill

[miguelangaranocurrents]

User description

builds and passes in currents-mcp is red on every monorepo PR that touches
the shared MCP source. Both causes are host-only files, which that check says
can only be fixed here.

server.registerPrompt is not a function

currents-dev/currents#3780 registers each skill as a prompt as well as a
resource, so createMcpServer calls registerPrompt. src/host/readme.test.ts
builds a server only to read the registered tool names off it, and its
McpServer mock carries registerTool and registerResource alone — the
suite threw before an assertion ran.

skills missing from README: browser-evidence

getSkills reads skills/ at build time and the README skills table has no
generator, so a skill added upstream fails that test until the row is written
by hand. browser-evidence landed in currents-dev/currents#3779 and failed
the sync check there too. The directory comes with the row because the row is
invalid without it; the next sync writes the same bytes over it.

Verified

npm run verify passes here (704 tests), and passes again with
currents-dev/currents#3780's shared source applied the way
mcp-source-sync-check.yml applies it (814 tests). Without either commit the
corresponding failure comes back.

Left out

currents-dev/currents#3780 also makes the README sentence "The server
publishes every skill as an MCP resource" incomplete — prompts belong beside
it. That is a change to code this copy has not received yet, so it should go
on the sync PR that brings skills.ts.

Generated description

Below is a concise technical summary of the changes proposed in this PR:
Add the browser-evidence skill and document it in the skills table, including trace normalisation guidance for publishing browser recordings. Extend the McpServer test mock with registerPrompt so createMcpServer remains compatible with the shared monorepo source.

Priority: ⬇️ Low

Estimated code review effort: 2 (Simple) | ~10 minutes

Change: Bug fix

Suggested reviewers: twk3

Merge Risk: 🟡 Moderate · up to cd26d

The new evidence workflow can expose development-session credentials through public trace links and may publish misleading or corrupted browser evidence. Address these issues before merging.

In `@skills/browser-evidence/references/normalise-trace.md`:
- Around line 50-55: Update the screencast-frame normalization block to generate
a collision-safe resource name for each source path instead of using only
basename(event['file']). Copy the frame under that unique name in resources and
assign the identical name to event['sha1'], preserving consistent trace lookup
when different files share a basename.

In `@skills/browser-evidence/SKILL.md`:
- Line 26: Update the trace-upload guidance to prohibit publishing raw
authenticated traces: require sanitizing cookies, authorization headers, tokens,
request bodies, and other sensitive data before upload, or use a
non-authenticated seeded account. Preserve the existing requirement to use
development/test data and stop if access requires a live user account.
- Line 84: Update the digest-fetching curl invocation to use --fail --silent
--show-error --location, ensuring HTTP 4xx and 5xx responses cause validation to
fail before posting evidence.
