Drop redundant bun entry points and export conditions

[sroussey]

A src/bun.ts that is byte-identical to src/node.ts bought nothing: it
produced a third bundle and a third .d.ts to keep in sync, while the code
Bun loaded was the same either way. With no "bun" condition in exports,
Bun falls through to the default "import" and gets the node build.

Removed the duplicate entry files, their --target=bun build/watch scripts,
their tsconfig.json entries, and the "bun" export conditions across every
package that had them, including the ones whose "bun" condition already
pointed at the node build (indexeddb, aws, postgres, supabase, duckdb, and
util's ./media and ./compress) and the workglow meta-package's nine
*.bun.ts provider re-export shims plus worker-bun.ts.

Kept the two entries where the Bun code genuinely differs:
@workglow/util's "." (Worker.bun vs Worker.node) and @workglow/sqlite's
./storage (bun:sqlite vs the node driver).

Docs and CLAUDE.md updated to describe the two-target build and the rule for
when a third Bun target is warranted.

Pull request overview

This PR removes redundant Bun-specific entry points and conditional exports across the monorepo, standardizing most packages on a two-target build (browser + node) where Bun simply consumes the node build via the default "import" condition. It keeps Bun-only targets only where Bun code genuinely differs (notably @workglow/util and @workglow/sqlite’s ./storage).

Changes:

• Removed byte-identical src/bun.ts (and related *.bun.ts shims) plus corresponding --target=bun build/watch steps where Bun does not need distinct code.
• Dropped "bun" export conditions that just pointed at node artifacts, letting Bun fall through to the default node "import"/"types".
• Updated tsconfigs and technical docs/CLAUDE guidance to reflect the two-target default and the “only add bun when it differs” rule.
