fix(platform): search mise shims dir so mise-installed CLIs are detected (#3319)

* fix(platform): search mise shims dir so mise-installed CLIs are detected

- Add ~/.local/share/mise/shims (and MISE_DATA_DIR override + legacy ~/.mise/shims) to wellKnownUserToolchainBins.
- This makes Pi, Kimi, and other mise-managed coding agents visible to the daemon even when launched from GUI contexts with stripped PATH.
- Added tests for default and MISE_DATA_DIR cases.
- Also pinned pnpm@10.33.2 in root mise.toml for better mise ergonomics.

Before/after: more local CLIs now appear in the runtime picker (Kimi, Pi, Antigravity, Kilo, etc.).

Refs: discussion in session around improving detection for common mise users.

* fix(platform): address Copilot review on mise shims logic

- Generalize the shims comment (no hard-coded CLI examples).
- Make per-version Node toolchain scanning respect MISE_DATA_DIR
  (use the same mise root for installs as for shims).
- Avoid duplicate shims entries when MISE_DATA_DIR makes legacy path
  identical to the primary one.

Addresses the three inline comments from copilot-pull-request-reviewer
on PR #3319.

* test(platform): extend MISE_DATA_DIR test to cover installs scanning

Addresses non-blocking review feedback from @nettee on PR #3319.

The previous test only asserted shims behavior under a custom
MISE_DATA_DIR. This extends it to also create fixture trees under
customMise/installs/node/... and customMise/installs/npm-openai-codex/...
and assert that the install paths are discovered while default-root
paths are excluded.

This makes the test robust against regressions in the installs
scanning logic (existingMiseNpmPackageBinDirs + node version dirs).

* fix(platform): only fall back to ~/.mise/shims when no MISE_DATA_DIR is set

Addresses the remaining non-blocking review comment from @nettee on PR #3319.

When an explicit MISE_DATA_DIR is provided, we no longer inject the
legacy ~/.mise/shims path. This prevents stale shims from a previous
mise layout from being re-introduced into detection.

Also added a regression assertion in the MISE_DATA_DIR test.

* fix(daemon): make claude-stream dedup robust when final assistant wrapper lacks msgId

Prevents duplicated text and thinking output (especially visible during
design system generation with AMR/Vela).

Root cause: the textStreamed guard fell back to  whenever the
final  message arrived without a string uid=501(ramarivera) gid=20(staff) groups=20(staff),12(everyone),61(localaccounts),79(_appserverusr),80(admin),81(_appserveradm),399(com.apple.access_ssh),33(_appstore),98(_lpadmin),100(_lpoperator),204(_developer),250(_analyticsusers),395(com.apple.access_ftp),398(com.apple.access_screensharing),400(com.apple.access_remote_ae) (common in some
AMR flows and design system tasks), causing the full content to be
re-emitted even if it had already been delivered via streaming deltas.

Fix: track whether any text or thinking was streamed via deltas for the
current message and use that as a reliable fallback for the final wrapper
instead of only trusting  presence.

* revert: remove dedup from claude-stream (PR #3319 should stay clean)
