af855e3394 refactor: Linus-style code quality improvements across Elisp and C modules 
- Extract shared binary search from duplicate ekp--hyphenate-p/ekp--flagged-p
- Remove duplicate ekp-root-dir definition (shadowed ekp-utils.el version)
- Remove dead ekp-clear-caches from ekp-utils.el (cleared non-existent var)
- Replace hardcoded 'zsh' with shell-file-name for portability
- Deduplicate module reload: shared ekp--module-reload for Rust/C
- Add NULL guard for ekp_global in ekp_paragraph.c (crash prevention)
- Track actual thread count in pool to fix destroy joining wrong count
- Normalize line endings (CRLF→LF) in ekp-utils.el

32021fbe35 Implement Looseness, Threshold Pruning, and Flagged Penalties 
Feature 1: Looseness (Complete Implementation)
- Added alt-paths hash table to track alternative paths by (position, line-count)
- Modified DP loop to track all paths reaching each position
- ekp--dp-trace-breaks-with-looseness uses alt-paths to find closest match
- Added ekp--dp-trace-alt-path helper with safety limit

Feature 2: Threshold Pruning
- Added ekp-threshold-factor variable (default 0 = disabled)
- Paths with demerits > best × (1 + factor) are skipped
- Tracks best-end-demerits during DP for pruning decisions

Feature 3: Flagged Penalties (Forced Breaks)
- Added flagged-positions field to ekp-para struct
- Added ekp-flagged-penalty variable (negative = preferred)
- Added ekp--flagged-p with O(log n) binary search
- Modified DP to always accept flagged breaks

Tests:
- ekp-test-unit--hyphenate-p-binary-search
- ekp-test-unit--flagged-p-binary-search
- ekp-test-unit--alt-paths-hash
- ekp-test-unit--threshold-factor
- ekp-test-unit--flagged-penalty
- Updated ekp-test-unit--struct-access for new fields

b70affb9ef Optimize hyphen position lookup O(n)->O(log n) and add named constants 
Performance:
- ekp--hyphenate-p: O(n) cl-find -> O(log n) binary search
- is_hyphen_break: O(n) linear -> O(log n) binary search
- is_hyphen_pos: O(n) linear -> O(log n) binary search

In O(n²) DP loop, this reduces worst-case complexity from O(n³) to O(n² log n)

Code quality:
- Add ekp-consecutive-hyphen-penalty (was hardcoded 100)
- Add ekp-forced-break-penalty (was hardcoded 10000)
- Add ekp-last-line-short-penalty (was hardcoded 50)
- Update ekp-looseness docstring noting partial implementation

fb58a9b19a Fix remaining global glue param usages in DP and glue distribution functions 
Code review found additional functions using global glue params instead
of para's stored params:
- ekp--compute-stretch-capacity: now takes para param
- ekp--compute-shrink-capacity: now takes para param
- ekp--line-badness-and-fitness: now takes para param
- ekp--dp-compute-line-demerits: now takes para param
- ekp--distribute-gap-adjustment: now takes para param

All capacity/distribution calculations now use para's stored glue params
for full consistency across multi-font paragraphs.

333618bb57 Fix glue parameter caching inconsistency for multi-font paragraphs 
When multiple paragraphs with different fonts were processed, subsequent
executions would use wrong glue parameters from the cache. This caused
misalignment because different fonts have different spacing values.

Changes:
- Add glue-params field to ekp-para struct to store params at creation
- Add helper functions: ekp--para-glue-ideal/shrink/stretch/min/max
- Update all C module interface functions to use para's stored params
- Update all glue computation functions for consistency
