Remove unused dependencies obsidian-dataview, uuid, minimatch, and matcher

None of these packages are imported anywhere in the codebase. Dataview
support was added in 602d25f for DQL 'TABLE' queries but the code was
subsequently removed without dropping the dependency; uuid, minimatch,
and matcher have no remaining references at all. @types/uuid goes with
uuid.

Beyond the dead weight, these were the source of a disproportionate
share of the project's outstanding vulnerability advisories.
obsidian-dataview pulls in obsidian-calendar-ui, which pins svelte 3.35
(nine advisories, including the SSR XSS in GHSA-wv8q-r932-8hc7) and
preact 10.26.7 (JSON VNode injection). uuid 8.x carries a missing
buffer bounds check, and minimatch 5.x an old brace-expansion with four
ReDoS/OOM advisories. Removing the packages resolves all of these
outright rather than forcing a breaking upgrade of obsidian-dataview,
which npm audit's suggested fix would have downgraded to 0.4.21.
