inputs/run: postprocess(): documented runtime (30 min)

bugfix: inputs/input.Makefile: %/postprocess.sql: don't perform replacements using map.csv, because map.csv is not idempotent. this functionality was only there to facilitate switching to new-style import, which is now largely done. (the remaining datasources NVS, SALVIAS, TEAM contain only 1 postprocess.sql: inputs/SALVIAS/projects/postprocess.sql (`st inputs/{NVS,SALVIAS,TEAM}/*/postprocess.sql`).)

bugfix: bin/repl: text mode: also don't match if it's part of a '-'-separated identifier

bugfix: bin/repl: text mode: also don't match if it's a word in a sentence

bugfix: bin/repl: text mode: turned off the suffix matching, because there are cases where a mapping adds a suffix which would cause the same replacement to be performed repeatedly

inputs/input.Makefile: %/postprocess.sql: always run this, not just if the associated map spreadsheets change, to avoid needing to `touch` them to cause %/postprocess.sql to run

bin/repl: text mode: exclude prefixes that should not cause replacement, to avoid doubling leading *

fix: inputs/*/*/postprocess.sql: un-doubled *

bugfix: inputs/input.Makefile: %/postprocess.sql: also need to apply renames from mappings/VegCore.thesaurus.csv, as these have been applied to map.csv

bugfix: lib/runscripts/table.run: custom_postprocess(): need to apply renames to SQL statements in postprocess.sql before it can be run
