routes: convert manual dispatch to @route + fix latent Bool/String crashes

Convert routes.el from ~89 hand-written dispatch branches to 75 @route-decorated
handlers with VBD roles (@manager/@accessor/@utility), driven by the modular
compiler's native @route dispatch. routes.elh updated to match.

Fix four latent bugs that the modular compiler surfaces (unlike the old inlining
compiler, it faithfully emits every source statement, so per-module compilation
no longer silently drops code):
  - safety.el: malformed soft-phrases literal (extra unescaped quote)
  - sessions.el: str_replace quote arg + topic_tags JSON escaping
  - memory.el mem_save and neuron-api.el consolidate: engram_save returns a Bool,
    not a String; str_eq(result, "") dereferenced the Bool value (0x1) as a char*,
    segfaulting the awareness loop on boot and POST /api/neuron/consolidate.
    Check it as a Bool (if !save_result). The old compiler dropped these checks,
    masking the bug in the shipped dist/soul.c.

Regenerate dist/soul.c through the bounded per-module path (modular elc per module
plus amalgamation that embeds dist/elp-c-decls.h), never by folding soul.el through
elc (27GB OOM). Verified on a throwaway snapshot and port: boots with the awareness
loop active and no segfault, @route dispatch matches the manual dispatcher across
all sampled routes and the four shadowing-hazard pairs, and consolidate returns 200.
