lrSv/srSv: human-readable SV type filter labels, script cleanups

Add human-readable labels to the supertrack-level svType filter on
both the lrSv and srSv supertracks using the "CODE|CODE (Long name)"
filterValues syntax: DEL -> "DEL (Deletion)", INS -> "INS (Insertion)",
etc. Labels keep the short code up front so users can match what
hgTracks shows next to each feature.

Also sweep in the in-progress converter/as-file cleanups under
scripts/lrSv/ and scripts/srSv/ (introduction of lrSvCommon.py
helpers, consistent insLen / svLen / AC column naming, tightened
field-description text) that had been piling up as an unstaged
working tree.

 <h2>Description</h2>
 <p>
 This track shows structural variants (SVs) derived from the Human Pangenome
 Reference Consortium (HPRC) release-2 pangenome graph. The graph was built
 with minigraph-cactus from PacBio HiFi haplotype-resolved assemblies of 233
 samples (including T2T-CHM13 and the diverse 1000 Genomes Project sample
 set). HPRC releases one VCF per reference path (GRCh38 and T2T-CHM13);
 we display both natively on the corresponding UCSC assembly (hg38 and hs1).
 Variants were extracted from the graph with <tt>vg deconstruct</tt> and
 decomposed into atomic alleles with <tt>vcfwave</tt> (WFA2-lib).
 </p>
 <p>
 The hg38 track contains 1,483,114 SV-sized alleles (length &ge; 50 bp) split
 by type: 1,106,190 insertions, 192,597 deletions, 178,178 complex alleles
 and 6,149 inversions. The hs1 track is built from the parallel T2T-CHM13
 wave VCF. Each row carries the allele count, allele frequency, number of
 samples with data and the snarl-nesting level of the variant in the
 pangenome decomposition tree.
 </p>
 
 <h2>Display Conventions and Configuration</h2>
 <p>
 Items are colored by SV type:
 <ul>
 <li><span style="color: rgb(0,0,200);">Insertions (INS)</span> - blue</li>
 <li><span style="color: rgb(200,0,0);">Deletions (DEL)</span> - red</li>
 <li><span style="color: rgb(140,0,200);">Complex alleles (COMPLEX)</span> - purple</li>
 <li><span style="color: rgb(230,140,0);">Inversions (INV)</span> - orange</li>
 </ul>
 </p>
 <p>
 Insertions are placed at the insertion site with a width of 1 bp; deletions,
 complex alleles and inversions span the affected reference interval.
 Filters are available for SV type, SV length, allele frequency and snarl
 level (0 = top-level bubble; higher values are nested within parent
 bubbles).

 <h2>Methods</h2>
 <p>
-The HPRC v2.0 minigraph-cactus pangenome was downloaded from the HPRC S3
-release bucket:
-<ul>
-<li>hg38:
-<a href="https://s3-us-west-2.amazonaws.com/human-pangenomics/pangenomes/freeze/release2/minigraph-cactus/hprc-v2.0-mc-grch38.sv.gfa.gz" target="_blank"><tt>hprc-v2.0-mc-grch38.sv.gfa.gz</tt></a> (graph) and
-<a href="https://s3-us-west-2.amazonaws.com/human-pangenomics/pangenomes/freeze/release2/minigraph-cactus/hprc-v2.0-mc-grch38.wave.vcf.gz" target="_blank"><tt>hprc-v2.0-mc-grch38.wave.vcf.gz</tt></a> (wave-decomposed VCF)</li>
-<li>hs1:
-<a href="https://s3-us-west-2.amazonaws.com/human-pangenomics/pangenomes/freeze/release2/minigraph-cactus/hprc-v2.0-mc-chm13.wave.vcf.gz" target="_blank"><tt>hprc-v2.0-mc-chm13.wave.vcf.gz</tt></a></li>
-</ul>
-The VCF is the result of running <tt>vg deconstruct</tt> on the graph with
-the corresponding reference path (GRCh38 or T2T-CHM13) and then
-<tt>vcfwave</tt> / WFA2-lib to split complex multi-allelic records into
-atomic alleles with per-allele TYPE and LEN fields.
+HPRC release-2 is an open data release (not yet accompanied by a formal
+peer-reviewed publication) built from PacBio HiFi haplotype-resolved
+assemblies of 233 samples, including T2T-CHM13 and a diverse 1000 Genomes
+Project panel. The pangenome graph was built with Minigraph-Cactus against
+both GRCh38 and T2T-CHM13 reference paths; variants were extracted from
+the graph with <tt>vg deconstruct</tt> and then decomposed into atomic
+alleles with <tt>vcfwave</tt> / WFA2-lib, yielding per-allele TYPE and LEN
+fields. For this track, each ALT in the wave VCF was emitted as its own
+BED row, retaining alleles with |LEN| &ge; 50 bp or the <tt>INV</tt> flag;
+allele counts, frequencies, sample counts and snarl levels are taken
+directly from the per-allele INFO fields. On hg38 this yields 1,483,114
+SV-sized alleles (1,106,190 insertions, 192,597 deletions, 178,178 complex
+alleles and 6,149 inversions); the hs1 track is built from the parallel
+T2T-CHM13 wave VCF. Sample-list and assembly provenance for the graph are
+maintained at HPRC in
+<a href="https://github.com/human-pangenomics/hprc_intermediate_assembly/blob/main/data_tables/pangenomes/alignments_v2.0.csv" target="_blank">
+hprc_intermediate_assembly/<tt>alignments_v2.0.csv</tt></a>.
 </p>
 <p>
-For display here, the wave VCF was streamed and each ALT was emitted as
-its own BED row. Alleles were retained if their absolute length was
-&ge; 50 bp or if the record carried the <tt>INV</tt> flag (inversions may
-be shorter). Allele counts, frequencies, and sample counts are taken
-directly from the per-allele INFO fields.
+The HPRC v2.0 Minigraph-Cactus graph and wave-decomposed VCFs were
+downloaded from the HPRC S3 release bucket:
