Multi-day accumulated fixes: tag dispatch, session/pooling correctness, SPA rollout, jetc compiler
JetCore engine (Tag.cpp/.h, Global.cpp/.h, __*.cpp tag classes): - Numerous __mysql.cpp connection-pooling correctness fixes (stale result sets, double-indirection sessionid bugs, field caching, pool keying) and a session-registration-before-connection-confirmed ordering fix (dangling pointer on a failed connect) - Tag.cpp: large body of fixes to the tag-dispatch/container-scanning logic (bare-name fallback, database aliasing, single-quote handling, @-prefix session variable resolution, TAGDEF caching, nested split-tag scanning for if/while/until/ifrow so an inner one doesn't corrupt an outer one's own boundary scan) plus the process-first rendering order fix (a <process> now runs before <checksession>/page resolution, fixing a real "blank page after successful login" bug) - Global.h/.cpp: added imapSessions (parallel to the existing __mysql* session map) for the new <imap> tag family - __whiledir.cpp/__include.cpp: caching and directory-name-aliasing fixes - __call.cpp/.h: fixed a dangling-pointer bug - __write.cpp: fixed an O_WRONLY-only open that couldn't create a new file - __ifrow.cpp/__sql.cpp: fixed the same sessionid double-indirection bug __mysql.cpp had (resolveKeyword's result was being used as a map key lookup instead of the resolved value itself) jetc compiler (jetc/JetParser.cpp/.h, JetCodegen.cpp/.h, JetAST.h, jetc.cpp, build-shared.sh, build-compiled.sh): - Parser fixes: inline <include>, nested-quote handling, void-tag recognition - Codegen fixes and expanded AST support - build-shared.sh: atomic rename into place for a freshly-built .jtc (a live server dlopen()ing the same path mid-rebuild was corrupting its own already-mapped view of the old file) and a staleness check so a cached JetCore .o doesn't silently keep serving yesterday's fixes forever - Added -lssl to both build scripts' link lines (needed once the new <imap> tag's client-side TLS code existed - previously nothing in this codebase used OpenSSL's SSL/TLS client API, only libcrypto) Site content (jetc/barant-site/): SPA (fetch-and-swap navigation) rollout across essentially every .page/.jet/.section/.tag/.proc/.method file - dynamic-content fixes, fragment-mode stripping, native $[@name] session variables replacing older mechanisms, and this session's own checkout.page redesign, login start-param redirect fix, and per-page side-menu (menu.bar/$[PAGE].menu) refresh support. Completed the earlier main.css/control.css move from assets/ to assets/images/ (git still showed the old paths as tracked-but-deleted until now). Deliberately left out of this commit: dozens of .pre-<description>- <date> manual backup files (this session's and earlier ones' own before/after snapshots, not meant for permanent history), compiled .jtc build outputs, ad hoc test binaries and scripts under jetc/ (login_asan, wcwc_test, optest2_bin, etc.), and jetc/__pycache__/ - none of these are meant to be tracked; a .gitignore covering them would be worth adding separately. |

Add jetc: a prototype JET-to-C++ compiler, plus the Tag API it needed
jetc (JetCore/jetc/) compiles a subset of JET template syntax - literal text, $[...]/#[...] variable output, <set>, <if>/<else>, <for>, <while> - into a standalone C++ program that links against CoreUtils and the same JetCore tag-class library jet-2.0 itself uses. The static tag/text structure becomes real C++ control flow (if/for/while), resolved once at build time instead of being re-scanned character-by-character from raw source on every request and, for loop bodies, on every single iteration (confirmed by reading Tag::parseContainer - it re-tokenizes its container text from scratch every time it runs, since a tag's parse and its execution are the same pass in this codebase). Anything genuinely dynamic - variable values, expr/value comparisons, loop bounds - still calls into the existing runtime (Tag::getVariable/resolveKeyword, jet::Operand) exactly as the interpreter does; compiling doesn't try to eliminate that; only the repeated re-parsing of the template's own shape. A <if type="..."> or <while type="..."> comparison type is resolved to its C++ operator once at compile time (type is a literal attribute value in practice, not runtime data) instead of being re-checked against six string constants on every evaluation. Any tag jetc doesn't have a codegen rule for (mysql, sql, call, include, a <set> with a container body, etc.) is captured as its exact raw source span and handed to the existing interpreter at compiled-program runtime via the new Tag::interpretSpan(), so an unsupported construct degrades gracefully instead of failing to compile - a real, if narrower, program rather than requiring full tag coverage up front. Tag.h/.cpp: made assignVariable public (parallel to the already-public getVariable - generated code needs a write path without being a Tag subclass) and added interpretSpan() as the fallback's entry point into parseContainer. Verified live: two representative templates (jetc/demo.jet, an if/for/set walkthrough; jetc/demo2.jet, a nested <if> inside a <for>, a <while> that mutates and rereads its own condition variable across iterations, and a fallback-interpreted <comment> tag) both compile, link, run standalone, and produce byte-identical output to jet-2.0 running the same source. Building and running jetc/demo2.jet's <while> loop surfaced a real, previously-unknown MString bug (fixed separately, see CoreUtils commit 6e4e463) along with a separate, already-existing bug in __while.cpp's value1/value2/type form (unrelated to this compiler, not fixed here - see project memory). jetc/build-compiled.sh builds the compiler and a given .jet file's compiled binary in one step; jetc/demo.jet and demo2.jet are kept as worked examples. Known limitations: <set> with a container body isn't modeled (falls back to interpretation); a fallback-interpreted tag nested inside compiled control flow uses the template's single top-level scope for parent/local context rather than a faithful per-level chain, which only matters for legacy tags that rely on nested "local" scoping.
