Extract the post-tool text-block selection logic into a small pure
helper (`findLatestPinnableText`) so the regression scenario can be
covered without standing up the full interactive controller harness.
The new test pins the bug from #4120: when content blocks are
`[text1, tool1, text2_streaming]`, the helper must return `text1`
(not `text2`), because `text2` is still streaming live into the chat
container and mirroring it would render the same tokens twice.

The pinned `Working · Latest Output` border above the editor mirrors
the assistant's latest text block while tools run, so prose stays
visible after a tool's output scrolls it off-screen. The mirror walked
content blocks from the end and picked the last text block — but when
the assistant streams a *new* text block after a tool call (sequence
`[text1, tool1, text2_streaming]`), it picked `text2`, which was also
being streamed live into the chat container. Result: identical tokens
rendered in two places at once.
Restrict the search to text blocks whose index is strictly less than
the index of the most recent tool call. Text after the last tool call
stays in the chat container only; earlier prose (e.g. `text1`) remains
mirrored the entire time the new text streams, so context isn't lost
and the loading-animation handoff is undisturbed.

PR #3564 narrowed the internal overlay to @gsd* prefixes only, which
dropped non-hoisted optional deps like @anthropic-ai/claude-agent-sdk
from the merged ~/.gsd/agent/node_modules directory. Revert to overlaying
all non-dotfile internal entries so optional deps resolve correctly.
- Use content fingerprint (packageRoot + sorted entry names from both
dirs) in .gsd-merged marker so pnpm add/remove triggers rebuild
- Restrict overlay loop to @gsd* scopes only, preventing accidental
shadowing of hoisted deps with internal versions
- Guard marker write behind linkedCount > 0 to avoid stamping success
on a broken/empty merged directory
- Log warnings when readdirSync fails on hoisted/internal roots

pnpm's virtual-store layout doesn't hoist @gsd/* workspace scopes to
the parent node_modules, so the simple symlink-to-hoisted approach from
the original fix (#3529) left workspace packages unresolvable.
Detect when workspace scopes are missing from the hoisted root and
create a real node_modules directory with symlinks from both the hoisted
root (external deps) and internal root (workspace packages). A .gsd-merged
marker file skips rebuild on subsequent startups.
Restores behavioral tests deleted in the original PR and adds unit tests
for the pnpm merge path and scope detection logic.

The pinned "Latest Output" zone was only cleared at agent_end, but during
flows with form elicitation (e.g. discuss-phase), there is a gap between
message_end and agent_end where the agent waits for user input. During this
gap, the same content was visible in both the chat history and the pinned
zone. Clear the pinned zone at message_end when the assistant message is
finalized in the chat container.
