listing: F5/Tab decompiles the function under the cursor (IDA-style) — step 2

In the continuous listing, F5 (or Tab) decompiles the defined function the
cursor is inside; F5/Tab again returns to the linear listing exactly where you
left. Not-in-a-function -> a message; decompile failure falls back to the
listing (not the bounded disasm). Listing position is snapshotted so the
round-trip is lossless.

Verified: continuous_view F5 round-trip + view_toggle/disasm_nav/follow_xrefs/
region_define/listing_view 45/0.
