fix linting warnings

[Vaivaswat2244]

Resolves partially: #9070

Changes:

Fixes all 143 oxlint warnings; npm run lint now exits clean. No lint config was changed. Every warning was resolved in code.

Mostly mechanical:

• unused imports, variables and orphaned functions removed
• bare catch {} for unused catch params
• == → ===
• // falls through on intentional switch fallthroughs
• { } around case bodies containing declarations
• dead if (0) blocks and unreachable post-throw code deleted

One behaviour change worth review: Renderer3D declared remove() twice. The first (canvas teardown, added in 2fa995a) was silently shadowed by a second added later in ef28cbc for _textCanvas, so wrappedElt cleanup has never run. I merged them, Renderer2D.remove() has the identical four lines, which is what it was meant to mirror. WebGL/WebGPU canvases are now actually detached on remove().

Two edits look behavioural but aren't: return FES.internalError(...) is unreachable (it always throws), and if (0) → if (debug) in textCore.js uses a param that arrives falsy.

Screenshots of the change:

PR Checklist

• npm run lint passes
• [Inline reference] is included / updated — N/A, no public API changes
• [Unit tests] are included / updated — N/A, no behaviour to cover; existing suites pass unchanged

Verification

• npm run lint -> 0 warnings (was 143)
• npm run build -> passes
• unit-tests -> 2098 passed, 0 failed
• webgpu p5.Shader + p5.Framebuffer -> 105 passed, 0 failed

WebGPU visual cases and p5.RendererWebGPU were not run locally cuz no software WebGPU adapter available :) leaving those to CI.
