Commit Message

v1.29.4: Drop redundant merges + defensive copy in observations + training (#177)

Two micro-optimizations on the observations / training-table hot paths:

1. **Single-column merges → .map()** in generate_observations_table.
   The pmid_meta_df merge contributes one column (quantification_method)
   and the _pmid_counts merge contributes one column
   (matched_sample_count). Replace both with .map() lookups to skip the
   pandas block-manager consolidation pass that dominated their cost.

2. **Drop second .copy() in generate_training_table**: the binding
   branch redundantly copies a fresh DataFrame returned by
   generate_binding_table. The earlier ms.copy() is kept since
   generate_observations_table can return a filtered view.

End-to-end on the built observations index (warm cache):
- generate_observations_table: 22.6s → 15.6s (~31% faster, ~7s saved)
- generate_training_table(both): 32.4s → 27.9s (~14% faster)

Combined with #174 / #175, the function has gone from 34.8s → 15.6s
across three PRs — a 2.2x speedup overall. Match-type distribution and
output schema are unchanged.

Build-pipeline profiling (peptide_mappings + observations builds, the
next 10s-of-seconds of wall-clock) is filed as #176 separately.
