apl: glyph audit — ⍉ ⊢ ⊣ ⍕ wired (+6 tests, Phase 9 complete)

Glyph parser saw these but runtime had no mapping:
- ⍉ monadic + dyadic transpose (apl-transpose, apl-transpose-dyadic)
- ⊢ monadic identity / dyadic right (returns ⍵)
- ⊣ monadic identity / dyadic left (returns ⍺)
- ⍕ alias for ⎕FMT

Pipeline 99/99.  All Phase 9 items ticked.

Remaining gaps (next phase): ⊆ partition, ∪ unique, ∩ intersection,
⍸ where, ⊥ decode, ⊤ encode, ⍎ execute — parser recognises
them but runtime not yet implemented.
