v2.60.0

A community bug-fix bundle — three external contributions plus the three issues they filed, integrated with the contributors credited as co-authors.

Frame accuracy (edit_engine) — MediaPool.AppendToTimeline clipInfo endFrame is an exclusive bound (duration = endFrame - startFrame), but three plan builders wrote an inclusive end (round(t*fps) - 1) and execute_selects advanced its record cursor by end - start + 1. Result: plan_tighten kept ranges were one frame short per segment (~4.3s across 130 segments), plan_selects/plan_swap source ranges were one frame short, and execute_selects left a 1-frame gap between selects. Now half-open everywhere. (#82, thanks @chenyuxiaojin)
Timeline rename no longer archives (destructive_hook) — timeline.set_name was version-on-mutate, so renames spawned redundant _archived timelines (and renaming an archive archived the archive). A rename is content-preserving, so it's out of the destructive registry. (#83, thanks @chenyuxiaojin)
Windows startup (server) — initialize the Resolve scripting env (PYTHONHOME, PATH, os.add_dll_directory) before importing the fusionscript bridge, avoiding a native access violation that crashed network transports before bind. No-op off Windows. (#78, thanks @POLEPALLIANVESH)
Fixed a stale offline test that patched a refactored-away seam (project_manager delete routing), restoring a fully green baseline.

execute_tighten(..., include_details?) — the readback structural_diff is compact by default (counts + a small head/tail sample) instead of embedding every before/after item id (226 KB for a 130-segment tighten). The full per-item diff is persisted in the plan record (get_plan → execution_summary.structural_diff) and returned inline with include_details=true. (#84, thanks @chenyuxiaojin)
plan_tighten skip dedup — identical (item, reason) skip rows collapse into one entry with a count. (#81, thanks @chenyuxiaojin)

Recorded the AppendToTimeline endFrame exclusive-bound semantics in the api_truth ledger. (#80, thanks @chenyuxiaojin)

Full offline suite green (1343 tests). Static/drift guards pass.
Live Resolve validation on Studio 21.0 — 30/30 checks, including selects butt-joined, no 1-frame gaps and tighten keep-ranges frame-exact (planned=118 actual=118).
