Publish canonical lens database release asset

[partyplatter08-lab]

Scope

This companion PR supports gyroflow/gyroflow#742 by publishing the canonical camera/lens database as a release asset next to profiles.cbor.gz.

What changed

• Added canonical_lenses.json at the repository root.
  • Current generated contents: version 37, 258 brands, 52 mounts, 2,638 cameras, 7,111 lenses, and 6,517 observed setup rows.
  • Sources recorded in the file:
    • gyroflow/lens_profiles commit bf0976d039d27a64b54517adfa941443865a492e
    • lensfun/lensfun commit 01e64b74507d9b818478f0e02f338fada8dd5680
• Updated compress.rs so canonical_lenses.json is not packed into profiles.cbor.gz as a legacy lens profile.
• Updated .github/workflows/release.yml so releases include both:
  • profiles.cbor.gz
  • canonical_lenses.json

Why

The app-side gyroflow/gyroflow change downloads canonical_lenses.json through the existing lens profile update path. Keeping this file as a separate release asset avoids changing the existing profile bundle format while giving the app a canonical identity/index database for later selector and compatibility work.

Validation

• git -c core.whitespace=blank-at-eol,blank-at-eof,space-before-tab,cr-at-eol diff --check
  • Passes in gyroflow/lens_profiles.
• The same canonical_lenses.json is present in both repos:
  • gyroflow/resources/camera_presets/canonical_lenses.json
  • lens_profiles/canonical_lenses.json
