LinxISA v0.4.0

Canonicalization

• Promoted v0.4 to the only live canonical ISA profile in this repository.
• Repointed generators, validators, regression defaults, and public docs to isa/v0.4/linxisa-v0.4.json.
• Kept v0.3 materials as archived history only.

Architecture

• Froze the v0.4 shader-kernel contract:
• structured MPAR/MSEQ kernel bodies
• p as 64-bit EXEC
• V.CMP.* ->p
• unified operand-derived l.* / v.* kernel domain
• l.*.brg and v.*.brg as canonical kernel memory forms
• Froze the first rendering profile:
• 4KB generic tile carriers
• 1024x1 row-major fragment-list profile
• SoA fragment/state tiles
• TAU tile-to-tile restriction

Spec Hygiene

• Converted contradictory legacy fragments from provisional canon into archived history plus reserved/illegal v0.4 behavior.
• Added active-content audit gating for stale v0.3, draft, forbidden-path, and incomplete-marker leaks.
• Updated the public manual, architecture contract, bring-up docs, and examples to the v0.4 baseline.
