chore(deps): redis 8, tiktoken 0.14, openapi3-parser 2, daytona 0.211, reportlab 5

Major bumps whose ceilings had to move. redis 8.1.0, tiktoken 0.14.0 and
daytona 0.211.2 needed no code change (the Daytona client, filesystem and
process signatures the sandbox calls are unchanged; redis 8 was checked
against a live server through the app's own sync and async clients).
reportlab 5.0.1 is test-only.

openapi-parser 2.0.0 is a rewrite onto pydantic spec models: `paths` is now
a dict keyed by URL rather than a list of objects carrying their own `url`,
and a path item exposes one field per HTTP method instead of an `operations`
list. `OpenAPI3Parser` reads both accordingly, iterating methods in the
order the spec declares them, and its rendered output is byte-identical to
before. The rewrite also drops prance, openapi-spec-validator and five more
transitive packages.

tokenizers stays at 0.22.2: transformers 5.8.1 caps it at <=0.23.0 and no
such release exists, so it moves with the transformers cap or not at all.
