Bump mlir-air to dfa6d08, drop mlir-aie-hash.txt

[erwei-xilinx]

Summary

• Bump utils/mlir-air-hash.txt to dfa6d08 / 2026050805 (latest mlir-air no-rtti wheel).
• Delete utils/mlir-aie-hash.txt. The new mlir-air wheel exposes a [aie] extra that pins the matching mlir_aie commit and requires llvm-aie, so we no longer need to maintain a separate aie hash file by hand.
• Collapse the two-step pip install mlir_aie==... && pip install mlir_air==... flow in env_setup.sh, env_setup.ps1, setup.py's get_install_requires, and .github/workflows/build.yml into a single pip install "mlir_air[aie]==<ver>".

The new air wheel's METADATA contains:

Provides-Extra: aie
Requires-Dist: mlir_aie==0.0.1.2026050723+52dd9bc.no.rtti; extra == "aie"
Requires-Dist: llvm-aie; extra == "aie"

So mlir-air[aie]==0.0.1.2026050805+dfa6d08.no.rtti resolves the whole MLIR-AIE/AIR/LLVM-AIE stack with a guaranteed-compatible mlir-aie. The mlir-aie commit can never drift out of sync with mlir-air anymore.

The .ps1 script also previously referenced mlir-aie-hash-windows.txt, llvm-aie-hash-windows.txt, and mlir-air-hash-windows.txt -- none of which exist in utils/. The new single-install path uses the existing mlir-air-hash.txt so it actually works.

Test plan

• pip install "mlir_air[aie]==0.0.1.2026050805+dfa6d08.no.rtti" in a fresh venv resolved mlir-air dfa6d08, the air-pinned mlir-aie 52dd9bc, and llvm-aie 21.0.0.2026050801+783f8625 in one shot.
• setup.py:get_install_requires() returns ['mlir-air[aie]==0.0.1.2026050805+dfa6d08.no.rtti'].
• CI build (build.yml) passes on the bumped versions.
• NPU hardware tests (small.yml) pass.

Pull request overview

This PR updates Triton-XDNA’s MLIR dependency management by bumping the pinned mlir-air wheel version and switching to mlir_air[aie] so that mlir-aie and llvm-aie are resolved transitively, eliminating the need to maintain a separate mlir-aie hash file.

Changes:

• Bump utils/mlir-air-hash.txt to commit dfa6d08 / timestamp 2026050805.
• Delete utils/mlir-aie-hash.txt and collapse installs to a single pip install "mlir_air[aie]==..." flow.
• Update setup scripts and CI to use the [aie] extra and adjust documentation accordingly.

utils/mlir-air-hash.txt	Updates pinned mlir-air commit/timestamp used for installs.
utils/mlir-aie-hash.txt	Removes now-unneeded separate mlir-aie pin file.
utils/env_setup.sh	Switches to single-shot install via mlir_air[aie] and derives MLIR_AIE_INSTALL_DIR from the installed wheel.
utils/env_setup.ps1	Same as bash setup: single-shot [aie] install and working hash file reference.
setup.py	Updates install_requires to depend on mlir-air[aie] only.
README.md	Documents new pinning approach and transitive resolution behavior.
.github/workflows/build.yml	Updates CI install step to use mlir_air[aie] instead of separate installs.

• In this step you compute MLIR_AIE_INSTALL_DIR_STR and write MLIR_AIE_INSTALL_DIR=... to $GITHUB_ENV, but the subsequent path exports use ${MLIR_AIE_INSTALL_DIR} (not set in the current shell), which will expand to empty and add incorrect /bin, PYTHONPATH, and LD_LIBRARY_PATH entries. Assign MLIR_AIE_INSTALL_DIR="$MLIR_AIE_INSTALL_DIR_STR" before using it (or consistently use *_STR for the path writes).

      # Set environmental variable "MLIR_AIE_INSTALL_DIR"
      MLIR_AIE_INSTALL_DIR_STR="$(python3 -m pip show mlir_aie | grep ^Location: | awk '{print $2}')/mlir_aie"
      echo "MLIR_AIE_INSTALL_DIR=$MLIR_AIE_INSTALL_DIR_STR" >> $GITHUB_ENV
      # Update paths in environmental variables
      echo "${MLIR_AIE_INSTALL_DIR}/bin" >> $GITHUB_PATH
      echo "PYTHONPATH=${MLIR_AIE_INSTALL_DIR}/python:$PYTHONPATH" >> $GITHUB_ENV
      echo "LD_LIBRARY_PATH=${MLIR_AIE_INSTALL_DIR}/lib:$LD_LIBRARY_PATH" >> $GITHUB_ENV

Addressed Copilot review comments in dc69e79:

• llvm-aie not upgraded (comment 1, comment 2): the [aie] extra requires llvm-aie without a version pin, so an existing installation silently satisfies it. Added an explicit pip install --upgrade llvm-aie -f .../nightly step in env_setup.sh, env_setup.ps1, and .github/workflows/build.yml (in CI also --force-reinstall). This matches the prior script behavior of always tracking the nightly llvm-aie wheel.
• Unquoted ${SCRIPT_PATH} in dirname (comment 3): quoted it, plus also quoted the PATH/PYTHONPATH/LD_LIBRARY_PATH exports for consistency.
