fix: TS2353 parameters property not in plugin type — blocks all dependabot PRs

[four-bytes-robby]

Bug

5 tool files use parameters property which no longer exists in the @opencode-ai/plugin type definitions:

• src/tools/blast-radius.ts:8
• src/tools/bus-factor.ts:8
• src/tools/curse-score.ts:8
• src/tools/implicit-coupling.ts:8
• src/tools/ownership.ts:8

This causes bun run typecheck → tsc --noEmit to fail on main, which blocks all 5 open dependabot PRs (#2, #3, #5, #6, #7).

Fix

Replace parameters: with the correct property name from the plugin SDK (likely args based on the tool type definition pattern). Verify with bun run typecheck after fix.

This was already fixed in commit b2229e6 (merge of git-tools analytics). All 5 tool files already use args: with the modern tool.schema.* syntax. Verified:

• rg 'parameters:' src/ --type ts → 0 results
• bun run typecheck → 0 errors

Closing as completed.
