fix: remove duplicate-word typos across SDK error, run-engine docs, and schemaTask doc

[devteamaegis]

Summary

Four small duplicated-word typos:

File:line	Fix
`packages/trigger-sdk/src/v3/ai.ts:861`	`Cannot convert this task to to a tool` → `Cannot convert this task to a tool` (user-facing error message thrown by `assertTaskUsableAsTool`)
`internal-packages/run-engine/src/engine/index.ts:1587`	JSDoc: `Send a heartbeat to signal the the run is still executing.` → `...the run is still executing.`
`internal-packages/run-engine/README.md:192`	`created with the the global scope` → `created with the global scope`
`docs/tasks/schemaTask.mdx:27`	`a schema parser function from a schema library or or a custom parser function` → `...or a custom parser function`

Diff is exactly 4 lines + 1 changeset entry (patch for `@trigger.dev/sdk` since `ai.ts` is in a public package).

Novelty

`gh pr list --search` for each phrase across the repo returned no open PRs touching these lines. No open typo PR at all.

Test plan

• All edits are JSDoc/comment/error-string/doc-only — no runtime/type behaviour change.
• `grep -rn 'the the \|to to a tool\|or or a custom'` across the changed files returns no matches after the fix.

This PR corrects five separate typos and documentation inconsistencies across the trigger.dev SDK. The changes include fixing a duplicated "to" in an error message for assertTaskUsableAsTool, correcting a "the the" typo in a JSDoc comment for heartbeatRun, refining wording in schemaTask documentation, clarifying guidance in run-engine README about idempotencyKey usage, and documenting the patch release via changeset.
