Devansh Patel b8bd073f05 python3-cbor2: Fix CVE-2026-26209
Scarthgap already contains 4810cd8c5b [3], which backports
fb4ee161 and e61a5f36 for read-ahead/read-size handling. The
associated submission [4] labels that work as CVE-2026-26209, but
it does not add the max_depth protection required for uncontrolled
recursion [2].

Complete the existing backport with the 5.9.0 max-depth chain:
- bcb6cea4: add the C decoder depth limit [1]
- 94e0d212: add the security-essential pure-Python depth limit
- 53521e7c: apply the required type correction
- a7ac10d5: raise the default depth limit to 400
- d903d62c: synchronize the C function signature default

The 5.9.0 upgrade description [5] also identifies max_depth as the
CVE fix. Full upstream commit links are recorded in the embedded
patch headers.
