fix(tui): pin OpenTUI to 0.3.4 to match OpenCode 1.17.11 (#200)

OpenCode 1.17.11 reverted bundled OpenTUI 0.4.2 -> 0.3.4, but the plugin
pinned ^0.4.2 as a regular dependency, so npm installed a second OpenTUI
0.4.2 in the plugin tree. The sidebar then mounted 0.4.2 renderables into
the host's 0.3.4 renderer, which kept the TUI process burning CPU at idle
(additive per sidebar plugin). Pin @opentui/core + @opentui/solid to 0.3.4
to match the host so the sidebar shares a single, version-matched OpenTUI.

Peer-only deps are not viable: the OpenCode TUI loader does not resolve
host-provided @opentui/* for raw-TS tui.json plugins, so a peer-dep flip
re-breaks with MODULE_NOT_FOUND (the original 1.17.10 failure). A host-side
loader fix is being tracked upstream as the durable resolution.

+## Fixes

+- **High idle CPU in the TUI sidebar (#200).** OpenCode 1.17.11 reverted its bundled OpenTUI from 0.4.2 back to 0.3.4, but Magic Context had pinned OpenTUI 0.4.2. That version mismatch made the sidebar mount UI objects built against a different OpenTUI than the host renderer, which kept a TUI process burning CPU even when the session was idle. The cost was additive per sidebar plugin (the same mismatch affected other sidebar plugins too). OpenTUI is now pinned to 0.3.4 to match OpenCode 1.17.11, so the sidebar returns to baseline idle CPU. Thanks to @null-axiom for the report and the cross-plugin cross-check that pointed straight at the shared dependency.
+
+We're also working with the OpenCode team on a host-side fix so TUI plugins always share the host's OpenTUI runtime, which removes this class of version-mismatch entirely.
