Adds pe1c (XF:28ID1-ES{Det:PE1}) and pe2c (XF:28ID1-ES{Det:PE2}) as ContAcqDetectors with proc_suffix="Proc1:", writing TIFF to J:\\proposals via a Windows NSLS2PathProvider — the hextools PE setup, with PDF's current file format and share.

• ophyd-async and nslsii now come from the same git commits hextools locks: ContAcqDetector(proc_suffix=...) (ophyd-async #1329) and NSLS2PathProvider(base_write_dir=...) (nslsii #231) are not in a release yet. Switch back to release pins once they are.
• #1329 renamed trigger_info_from_num_images → trigger_info_from_driver; the XSP (Lambda) driver is updated.
• nslsii main requires BEAMLINE_ACRONYM/ENDSTATION_ACRONYM; the profile now defaults BEAMLINE_ACRONYM=PDF.
• Both IOCs have CB1:, Proc1: and HDF1: plugins (checked with cainfo 2026-10-23).

Verified: mock tests only — a mock PE count with Proc filtering and TIFF on the Windows share (tests/test_detectors.py/test_perkin_elmer.py), and the profile booting in mock mode with pe1c/pe2c initialised. Not yet run on the TST or real beamline.

What changed in this PR

Adds Perkin Elmer PE1 and PE2 to the collection profile as continuous-acquisition detectors, using Proc1 frame summing and TIFF output on the Windows proposals share.

Changes:

• Configures both detectors and their Windows write-path provider.
• Pins dependencies to commits supporting the required APIs and updates the Lambda driver.
• Adds mock acquisition coverage and extends profile startup checks.

File	Description
tests/​test_utils.py	Checks that both PE detectors initialize in mock mode.
tests/​test_detectors.py/​test_perkin_elmer.py	Tests mock PE acquisition, filtering, TIFF paths, and metadata.
src/​pdftools/​profiles/​collection.py	Adds PE detectors, Windows write paths, and the beamline acronym default.
src/​pdftools/​detectors/​xspd.py	Adapts the Lambda driver to the renamed trigger helper.
pyproject.toml	Pins ophyd-async and nslsii to required Git commits.
pixi.toml	Aligns environment dependencies with those Git pins.

🔵 Needs a closer look

Validation is limited to mocks; live detector acquisition and Windows-share TIFF writing still require human review.
