  1. Reject unsupported identity transform types (apache#3517) 

    <!--
Thanks for opening a pull request!
-->

# Rationale for this change

Per spec[1], the identity transform source type must be any primitive
except for geometry, geography, and variant. This PR rejects
GeographyType and GeometryType as source types for identity
transforms.(No VariantType yet)

  2. Prune dependency upper bounds (apache#3586) 

    This PR removes as many upperbounds restrictions as possible from our
dependencies.

Why remove unnecessary upper bounds:
- Makes PyIceberg easier to install alongside applications that already
use newer compatible dependency versions.
- Reduces resolver conflicts and forced downgrades for downstream users,
while keeping caps where there is a real compatibility boundary or known
bad version.

We already removed upperbound for pyarrow in apache#2258
And theres a request to remove upperbound for cachetools in apache#3214

Closes apache#3214

Changes:
- Removes upper bounds that passed local validation, while keeping the
remaining compatibility caps.
- Refreshes `uv.lock` with upgraded packages.
- Updates tests for newer Moto and PyArrow behavior exposed by the
lockfile refresh.

Validation:
- `make test PYTHON=3.12` (`3736 passed, 1534 deselected`)

  3. CI: Pass args through docker-compose (apache#3587) 

    # Rationale for this change

This way we pass in the MIRROR from docker-compose to the Dockerfile as
well. Also git-ignore the `.env` file to avoid checking in this file.

  4. Fix strip spec-mandated DV blob framing before deserializing (apache#… 

    …3576)

# Rationale for this change

Fix `_payload` storing `puffin[8:]` instead of `puffin` — blob offsets
in the footer are file-relative (from byte 0), not relative to byte 8.
The two bugs cancelled for single-blob files at offset 4; the fix was
only testable once PuffinFile supported multi-blob/compressed files.

Also widen `PuffinBlobMetadata.type` from
`Literal["deletion-vector-v1"]`
to `str` so `PuffinFile` can parse files containing non-DV blobs without
a Pydantic validation error.

## Are these changes tested?

Yes. Copied files from
https://github.com/apache/iceberg/tree/main/core/src/test/resources/org/apache/iceberg/puffin/v1
`sample-metric-data-compressed-zstd.bin` will be added separately in
apache#3575

No

  5. Bump to Java Iceberg 1.11.0 (apache#3389) 

    <!--
Thanks for opening a pull request!
-->

<!-- In the case this PR will resolve an issue, please replace
${GITHUB_ISSUE_ID} below with the actual Github issue id. -->
<!-- Closes #${GITHUB_ISSUE_ID} -->

# Rationale for this change

This reverts apache#3240 and we
now should be able to support custom `namespace-seperator`
