The type of this PR is: Refactor

Description

Migrates lodash imports from whole-library style (import { compact } from "lodash") to per-method style (import compact from "lodash/compact") across the codebase, enabling tree-shaking of unused lodash utilities.

https://claude.ai/code/session_01EHt5dM7Rts48s8HzcCaZCz

Import individual lodash methods (e.g., `import compact from "lodash/compact"`)
across ~170 files instead of importing the entire library, reducing bundle size
by tree-shaking unused methods.

Also adds a `yarn check:lodash` script and documents the rule in AGENTS.md to
prevent regressions.

The throttle mock targeted "lodash" but the source now imports from
"lodash/throttle", so jest.mock("lodash/throttle", ...) is needed.

Upgrade Biome from 1.9.4 to 2.4.2 to enable the noRestrictedImports
lint rule, which bans whole-library lodash imports (e.g.
`import { debounce } from "lodash"`) while allowing per-method deep
imports (e.g. `import debounce from "lodash/debounce"`).

New v2 rules that would flag pre-existing code are disabled to keep
this upgrade non-breaking. These can be enabled incrementally.

Hmm, Claude didn't just revert the change as asked — but is actually trying to delete this now?

Are all the new rules in this file already passing? Wondering how to make sense of these additions.

Ah I see, they were all set to "off" thus effectively disabled. Makes sense.

…s types

Now that Biome v2 has been upgraded and several rules disabled globally,
the corresponding biome-ignore suppression comments are unused and cause
lint errors. Remove them all.

Also fix type errors in countChangedFilters.ts introduced by the switch
from named to per-method lodash imports, which changed the type signature
of `transform`.

The curly typographic quotes were mangled during a previous restore.
Reset from main to ensure no unintended changes.

Enable the biome correctness/useExhaustiveDependencies lint rule (was
previously "off"). All existing violations are suppressed with
biome-ignore comments added via `biome lint --suppress`.

…ents

Re-enable rules that were disabled in the Biome v2 upgrade but had
existing biome-ignore suppressions on main:

- correctness/useExhaustiveDependencies (warn)
- correctness/useHookAtTopLevel (warn)
- suspicious/noAssignInExpressions (warn)
- suspicious/noThenProperty (warn)
- a11y/useKeyWithClickEvents (warn)
- a11y/useValidAnchor (warn)

Restore original biome-ignore comments (with their original reasons
rather than the generic "ignored using --suppress" text). Add
biome-ignore suppression for new violations introduced by the Biome
v2.4.2 upgrade detecting additional cases.
