fix: duplicated "the" in encoding/varint and crypto comments

[otjdiepluong]

Two one-line typo fixes for duplicated "the" in code comments:

• encoding/varint.ts — "written the the two's complement view" → "written the two's complement view"
• crypto/crypto.ts — "supported by the the runtime" → "supported by the runtime"

No code/behavior change.

Both comments had duplicated the — fix is correct. Comment-only, no test needed. CI green.

CLA shows pending — needs to clear before merge.

@bartlomieju this is ready to merge

Both edits are the obvious the the → the deletions in comments only, no behaviour change. CI is green; holding APPROVE until license/cla flips from PENDING (looks like the CLA signature hasn't registered yet).
